Electrical Panel Upgrades & Breaker Box Replacement

Your electrical panel is the central hub of your home's entire power distribution system. Every circuit, every outlet, every appliance depends on a panel that can safely deliver adequate amperage without overheating or failing. Older panels — especially Federal Pacific StabLok, Zinsco, Pushmatic, Challenger, Sylvania, and outdated fuse box models — are documented safety hazards linked to thousands of electrical fires annually. These panels can fail to trip during overloads and short circuits, leaving your home unprotected. If your property still runs on 60-amp or 100-amp service, it almost certainly cannot support today's electrical demands — air conditioning, electric ranges, EV chargers, home offices, hot tubs, pool equipment, and modern appliance loads. Our panel upgrade services include: 100A to 200A panel upgrades, 200A to 400A service upgrades for larger homes and dual-unit properties, sub-panel installations for garages, workshops, ADUs, pool equipment, and detached structures, main breaker replacement, meter base and weatherhead upgrades, bus bar repair and replacement, double-tap corrections, and complete breaker box replacements. We handle all permit applications, city inspections, and utility coordination with SCE (Southern California Edison) and SDG&E. Warning signs you need a panel upgrade: frequent breaker trips, flickering or dimming lights when appliances turn on, a burning or acrid smell near the panel, warm or discolored breakers, scorch marks inside the panel cover, reliance on power strips and extension cords, buzzing or crackling sounds from the breaker box, a panel with fewer than 20 spaces, or plans to add an EV charger, hot tub, solar system, generator, or workshop equipment.

Whole-House Rewiring & Electrical Repair

Homes built before the mid-1980s may contain hazardous wiring that presents serious fire and electrocution risks. Common dangerous wiring types found in Temecula-area homes include knob-and-tube wiring (pre-1940s homes), aluminum branch circuit wiring (1960s–1970s construction), cloth-wrapped wiring (1950s–1960s), backstabbed outlets and switches, undersized conductors that overheat under modern loads, deteriorated rubber and cloth insulation, and ungrounded two-prong outlet systems. Rewiring services: complete whole-house rewiring with modern copper NM-B (Romex) conductors, partial rewiring targeting the most hazardous circuits, aluminum wiring remediation using approved COPALUM crimps or AlumiConn connectors at every connection point, knob-and-tube replacement, grounding and bonding system upgrades, installation of GFCI outlets in kitchens, bathrooms, garages, laundry rooms, basements, crawl spaces, and outdoor locations, AFCI breakers for bedrooms, living areas, hallways, and closets, tamper-resistant receptacles throughout the home, and weather-resistant receptacles for all exterior locations. General electrical repairs: dead outlets, flickering lights, tripping breakers, buzzing switches, warm cover plates, sparking receptacles, intermittent power loss, loose connections, backstab failures, damaged wiring in walls and attics, melted wire insulation, open junction boxes, and improper splices. Our electricians perform thorough electrical troubleshooting and diagnostics to identify root causes — not just symptoms — using professional testing equipment including thermal imaging, circuit tracers, and megohm testers.

Interior Lighting Design and Installation

Professional lighting installation transforms the look, comfort, functionality, and energy efficiency of any home. Lock and Alert Electrical designs and installs complete interior lighting systems including recessed lighting (can lights / downlights) in standard, slim profile, and gimbal versions, LED retrofit kits for existing recessed housings, pendant lights, chandeliers, track lighting, monorail lighting, linear LED strip lighting, under-cabinet kitchen lighting (hardwired LED puck lights, tape lights, and light bars), vanity and bath bar lighting, sconce installation, cove and tray ceiling lighting, toe-kick lighting, closet lighting, pantry lighting, stairway and hallway illumination, and accent lighting for artwork, shelving, and architectural features. Lighting controls: dimmer switch installation (single-pole, 3-way, and 4-way dimmers), smart lighting controls including Lutron Caseta, Lutron RadioRA 3, Leviton Decora Smart, Philips Hue, Inovelli, and Zooz, occupancy and vacancy sensor switches, daylight harvesting sensors, timer switches, and whole-home lighting control panels.

Exterior, Landscape & Security Lighting

Well-designed outdoor lighting improves curb appeal, property value, safety, and security. Our outdoor lighting services include security floodlights, motion-sensor and dusk-to-dawn lights, LED wall packs, soffit-mounted downlights, pathway and walkway illumination, deck and patio lighting, pergola and gazebo lighting, string light installation with permanent mounting hardware, pool and water feature lighting, accent uplighting for trees, columns, and architecture, bollard lights, step and stair lights, driveway lighting, address sign illumination, post lights and lamp posts, outdoor ceiling fans with lights, and commercial parking lot lighting. We design and install complete low-voltage LED landscape lighting systems using premium transformers, direct-burial cable, and commercial-grade brass and copper fixtures built to withstand Temecula's intense sun and Santa Ana wind conditions. Full systems include pathway lights, well lights, spotlights, wash lights, hardscape lights, and multi-zone transformer controls with timers and photocells.

Ceiling Fan Installation & Replacement

Ceiling fans reduce energy costs, improve air circulation, and add style to any room. We install and replace ceiling fans with or without integrated lighting in bedrooms, living rooms, patios, porches, and commercial spaces. Services include ceiling fan rated electrical box installation (required by code for fan support), new wiring for fan and light switch separation, fan/light combo switch and remote control installation, downrod sizing for vaulted and high ceilings, outdoor and damp-rated fan installation, and smart ceiling fan integration with home automation systems.

Smart Home Automation & Whole-Home Technology

Transform your home with intelligent technology that enhances comfort, security, energy efficiency, and convenience. Lock and Alert Electrical installs, configures, and integrates a complete range of smart home systems: Climate and comfort: smart thermostats including Nest Learning Thermostat, ecobee Premium, Honeywell Home T9 and T10 Pro, Emerson Sensi, and Mysa, plus zone control systems and remote temperature sensors.

All installations are compatible with Amazon Alexa, Google Home, Apple HomeKit, Samsung SmartThings, Control4, Hubitat, and Home Assistant.

Standby Generator Installation & Backup Power Solutions

Power outages in the Temecula area from PSPS (Public Safety Power Shutoff) events, Santa Ana windstorms, summer heat wave grid overloads, wildfire-related shutoffs, and aging utility infrastructure can leave homes and businesses without power for hours or days. A whole-house standby generator automatically restores power within 10–20 seconds of an outage — keeping your refrigerator, HVAC, medical devices, security system, sump pump, and lights running without interruption. Generator brands we install: Generac Guardian and Protector series, Kohler, Cummins QuietConnect, Briggs & Stratton, and Champion. Systems are available in natural gas and liquid propane configurations from 10kW to 150kW+ for residential and commercial applications. Full-service generator installation includes: professional load sizing and calculation, concrete pad or composite mounting pad preparation, automatic transfer switch (ATS) installation, natural gas or propane line coordination with your fuel provider, sound attenuation planning, setback compliance, city permits and inspections, startup testing, owner training, and ongoing generator maintenance plans (oil changes, filter replacement, load bank testing, battery checks). We also install portable generator hookups including manual transfer switches, power inlet boxes, and interlock kits that allow safe, code-compliant connection of a portable generator to your home's electrical panel.

Whole-House Surge Protection

Power surges from lightning strikes, utility grid fluctuations, transformer switching, and internal sources like HVAC compressors and refrigerators cycling on can silently damage or destroy electronics, appliances, and sensitive equipment. A single surge event can cost thousands in replacement equipment — and cumulative low-level surges degrade device lifespan over time. A whole-house surge protection device (SPD) installed at your main electrical panel provides the first line of defense, clamping dangerous voltage spikes before they reach your home's wiring. We install Type 1 and Type 2 SPDs from Eaton, Siemens, Square D (Schneider Electric), Leviton, and Intermatic. For maximum protection, we also install point-of-use surge protection for home theaters, computer workstations, server rooms, home offices, medical devices, and high-value equipment. Whole-house surge protection is especially critical for homes equipped with generators, solar inverters, and battery storage systems.

Electrical Inspections & Safety Evaluations

Professional electrical inspections provide essential safety information for homebuyers, sellers, landlords, property managers, insurance companies, and homeowners concerned about the condition of their electrical system. Our comprehensive inspection covers: panel condition, age, brand, and capacity, wiring type and condition throughout the home, grounding and bonding system integrity, GFCI protection in required locations, AFCI protection in required locations, outlet and switch condition and function, 240V appliance connections, smoke and carbon monoxide detector compliance, exterior electrical condition, service entrance and weatherhead, meter base condition, visible junction boxes, attic and crawl space wiring inspection, and overall NEC code compliance assessment. You receive a detailed written report documenting all findings, safety concerns, code violations, and prioritized repair recommendations with estimated costs. Inspection types available: pre-purchase home inspection, pre-listing seller inspection, insurance compliance inspection, rental property inspection, annual safety inspection, and post-storm damage assessment.

Dedicated Circuit Installation & Outlet Additions

Many appliances and equipment require a dedicated circuit — a circuit that serves only one device — for safe operation and code compliance. Running high-draw equipment on shared circuits causes nuisance breaker trips, voltage drops, premature equipment failure, and potential fire hazards. We install dedicated 120V and 240V circuits for: home offices (computers, monitors, laser printers), hot tubs and spas (50-amp 240V), EV chargers (40-amp and 50-amp 240V), electric ranges and cooktops, wall ovens, electric dryers, HVAC systems (air conditioners, furnaces, mini-splits, heat pumps), workshops (table saws, welders, air compressors, CNC machines, plasma cutters), home theaters and media rooms, server racks and network closets, medical equipment (CPAP, oxygen concentrators, home dialysis), sump pumps and sewage ejector pumps, wine coolers and beverage refrigerators, chest freezers and garage refrigerators, electric fireplaces, saunas and steam rooms, aquariums and terrariums, and grow lighting systems. Outlet additions and upgrades: We add outlets anywhere you need them including GFCI outlets for all wet locations, weather-resistant outdoor outlets, USB-A and USB-C combination outlets, tamper-resistant receptacles, floor outlets for kitchen islands and open floor plans, recessed outlets for flat-screen TV mounting, hospital-grade outlets, and 240V outlets in configurations including NEMA 14-30 (dryers), NEMA 14-50 (ranges, EV chargers), NEMA 6-50 (welders, EV chargers), NEMA 6-30, and NEMA L6-30 (twist-lock for generators and commercial equipment).

Smoke Detector, Carbon Monoxide Detector & Fire Safety

California law requires working smoke detectors in every bedroom, in hallways outside sleeping areas, and on every level of the home, plus carbon monoxide (CO) detectors in all homes with fuel-burning appliances, attached garages, or fireplaces. Rental property owners face additional compliance requirements under California Civil Code 1102.6d. Our fire safety services: installation and replacement of hardwired, interconnected smoke detectors with battery backup, hardwired carbon monoxide detectors, combination smoke/CO detectors, interconnection of all units so when one alarm triggers they all sound, replacement of outdated battery-only units with modern hardwired models, photoelectric and dual-sensor smoke detector upgrades, smart smoke detectors (Nest Protect, First Alert Onelink, Kidde), heat detectors for kitchens, garages, and attics where smoke detectors cause nuisance alarms, and full rental property compliance packages for landlords and property management companies. Smoke detectors should be replaced every 10 years and CO detectors every 5–7 years regardless of whether they appear to be working. We verify manufacture dates and replace all expired units.

Pool, Spa & Hot Tub Electrical Wiring

Pool and spa electrical work requires specialized expertise in NEC Article 680, which governs bonding, grounding, GFCI protection, clearance distances, and wiring methods for swimming pools, hot tubs, spas, fountains, and similar installations. Improper pool electrical work is a life-safety hazard that can result in electrocution. Our pool and spa electrical services: code-compliant new pool electrical installations, pool pump and motor wiring (single-speed, dual-speed, and variable-speed), pool heater electrical connections (gas and heat pump), pool lighting installation and replacement (LED color-changing, fiber optic), hot tub and spa hookups (50-amp 240V dedicated circuits), spa disconnect installation, automated pool control systems (Pentair IntelliCenter, Hayward OmniLogic, Jandy AquaLink), pool equipment sub-panels, equipotential bonding grid installation and repair, GFCI protection for all pool circuits, underwater lighting transformer replacement, salt chlorine generator wiring, and pool electrical safety inspections.

Solar Panel Electrical Connections & Battery Storage

While we do not install the solar panels themselves, we perform the critical electrical infrastructure that makes solar possible: Solar electrical services: main panel upgrades to accommodate solar inverter connections and meet the NEC 120% rule, solar-ready sub-panel installations, meter base upgrades for net metering, service entrance upgrades, conduit and disconnect installation between inverter and panel, and coordination with your solar installer for seamless integration. Battery storage wiring: Tesla Powerwall, Enphase IQ Battery, Generac PWRcell, FranklinWH aPower, SonnenCore, LG RESU, and Panasonic EverVolt. We install critical loads sub-panels for battery prioritization so your most important circuits stay powered during outages, plus backup gateway and transfer switch installation.

Outdoor Electrical, Kitchen Islands & Entertainment Areas

Weatherproof outdoor outlet installation (GFCI-protected, in-use covers), outdoor kitchen and BBQ island electrical hookups (outlets, lighting, ventilation), patio and pergola lighting, permanent string light installation with commercial-grade mounting, outdoor ceiling fan circuits, electric gate and automatic driveway gate circuits, electric fence charger hookups, well pump circuits, irrigation controller wiring, fountain and pond pump electrical, detached structure electrical (sheds, barns, workshops, pool houses), and underground conduit and wire runs to outbuildings.

Structured Cabling, Data Wiring & Low-Voltage Systems

Modern homes and businesses depend on reliable network infrastructure. Lock and Alert Electrical installs professional-grade low-voltage cabling and network systems: Data and network: Cat6 and Cat6a Ethernet cabling, coaxial cable runs, fiber optic terminations, network rack and patch panel installation, wireless access point (WAP) placement for seamless whole-home Wi-Fi (Ubiquiti UniFi, TP-Link Omada, Ruckus), network switch installation, and structured wiring closet buildout.

Electric Vehicle Infrastructure & Fleet Charging

Beyond residential EV charger installations, Lock and Alert Electrical designs and builds commercial and fleet EV charging infrastructure projects: Multi-unit residential: EV charging for apartment complexes, condominium associations, and townhome communities. We handle load studies, panel and transformer upgrades, EVSE installation, power management systems, and HOA compliance documentation. Commercial and retail: Customer-facing and employee charging stations for office parks, shopping centers, grocery stores, restaurants, gyms, and entertainment venues. We install networked chargers (ChargePoint, Blink, EV Connect, FLO) with revenue management and usage reporting. Fleet and municipal: Depot charging infrastructure for delivery vehicles, service fleets, transit buses, school buses, and municipal vehicles. Load management, smart scheduling, and utility demand response integration.

Mini-Split & Ductless HVAC Electrical

Mini-split air conditioner and heat pump systems require dedicated electrical circuits and proper disconnect installation for safe, code-compliant operation. We install dedicated 240V circuits for mini-split condensers, disconnect switches within sight of outdoor units, whip and conduit connections, line-hide installation for clean aesthetics, multi-zone system electrical, and electrical for mini-split installations in ADUs, garages, and additions.

Attic Fan, Exhaust Fan & Ventilation Electrical

Proper ventilation reduces energy costs, prevents moisture damage, and improves indoor air quality. We install electrical for whole-house attic fans (QuietCool, Centric Air, Master Flow), solar-powered attic fans, bathroom exhaust fans (including fan/light/heater combos), range hood and kitchen exhaust fan wiring, laundry room exhaust fans, radon mitigation fan circuits, and commercial ventilation systems.

Electric Water Heater & Tankless Water Heater Circuits

Electric tank and tankless water heaters require properly sized dedicated circuits for safe operation. We install dedicated circuits for standard electric tank water heaters (30-amp 240V), high-amperage circuits for electric tankless water heaters (often requiring 2–3 dedicated 40-amp 240V circuits), hybrid heat pump water heater circuits, point-of-use water heater wiring, and recirculation pump circuits. We also perform the electrical disconnect and reconnect when your plumber replaces your water heater.

Knob-and-Tube Wiring Replacement

Knob-and-tube (K&T) wiring was installed in homes built before the 1940s and is considered obsolete and hazardous by modern standards. K&T wiring has no ground conductor, uses degraded rubber and cloth insulation that crumbles with age, cannot be covered with insulation per code (creating energy efficiency problems), and is frequently rejected by insurance companies or results in dramatically higher premiums. We provide complete knob-and-tube wiring removal and replacement with modern grounded NM-B copper wiring, including proper circuit separation, GFCI and AFCI protection, grounding, and panel upgrades as needed. This work dramatically improves safety, insurability, and property value.

Aluminum Wiring Remediation & Repair

Aluminum branch circuit wiring was used extensively in homes built during the 1960s and 1970s as a less expensive alternative to copper. Aluminum expands and contracts more than copper with temperature changes, leading to loose connections, arcing, overheating, and an elevated fire risk — particularly at outlets, switches, and splices. Remediation options: COPALUM crimp connectors (considered the gold standard by the CPSC), AlumiConn setscrew connectors (an approved alternative), and complete copper rewiring for the most comprehensive and permanent solution. We inspect and remediate every connection point — outlets, switches, fixtures, splices, and panel connections.

Electrical Code Corrections & Permit Resolution

Failed a city inspection? Received a code violation notice? Buying a home with unpermitted electrical work? We fix it all: Common code corrections: open and accessible junction boxes, improper or missing wire splices, missing GFCI protection in required locations, missing AFCI protection, ungrounded outlets, double-tapped breakers, improper panel wiring, missing bonding conductors, inadequate wire sizing, improper cable routing and support, missing electrical permits, unpermitted additions and remodels, and work performed by unlicensed contractors. We work directly with local building departments including the City of Temecula, Riverside County, City of Murrieta, City of Menifee, City of Lake Elsinore, City of Wildomar, and surrounding jurisdictions to resolve violations and close open permits.

New Construction & Remodel Wiring

Complete electrical for new construction: We work with builders, general contractors, and homeowners on new homes, custom homes, and ground-up construction. Services include load calculations, panel and meter base selection, rough-in wiring, low-voltage pre-wire, fixture and device trim-out, panel terminations, and coordination with inspectors. Remodel and renovation electrical: kitchen remodels, bathroom remodels, room additions, garage conversions, basement finishing, attic conversions, open floor plan conversions (removing load-bearing walls requires rerouting circuits), and whole-house renovations. We reroute, extend, and upgrade existing wiring to meet current NEC code and support new layouts and fixtures.

ADU, Granny Flat & Guest House Electrical

California's ADU (Accessory Dwelling Unit) laws have made it easier than ever to add rental income, multi-generational living space, or home offices on your property. Every ADU requires a complete electrical system: ADU electrical services: new sub-panel installations (100A or 200A), separate metering when required by the utility or desired for tenant billing, underground conduit runs from main panel to ADU, full rough-in and finish wiring, dedicated circuits for HVAC, kitchen, laundry, and bathroom, lighting and outlet layout design, smoke and CO detector installation, EV charger pre-wire, and coordination with city ADU permit requirements.

Commercial services: tenant improvement (TI) buildouts, commercial lighting design and installation, LED lighting retrofits with utility rebate assistance, 3-phase power installation and repair, machinery and equipment wiring, parking lot and area lighting, signage and monument sign electrical, fire alarm system installation and maintenance, emergency and exit sign lighting, commercial EV charging infrastructure, commercial generator installation, energy audits and efficiency upgrades, preventive maintenance contracts, commercial surge protection, dedicated circuits for commercial equipment, bus duct and busway installation, transformer installation and maintenance, motor control and starter wiring, commercial kitchen equipment wiring, and ADA compliance electrical upgrades. We schedule work around your business hours to minimize downtime and disruption to your operations.

Electrical for Electric Fireplaces, Saunas & Specialty Appliances

We install dedicated circuits and connections for electric fireplace inserts, linear wall-mount fireplaces, infrared saunas, traditional electric saunas, steam shower generators, heated towel racks, heated bathroom mirrors, bidet toilet seat outlets, garbage disposal circuits, instant hot water dispensers, trash compactors, electric cooktops and induction ranges, wall ovens (single and double), warming drawers, wine refrigerators, beverage centers, and ice makers.

Radiant Floor Heating Electrical

Electric radiant floor heating systems provide luxurious comfort in bathrooms, kitchens, entryways, and living areas. We install dedicated circuits and thermostats for electric radiant heat mats (Schluter DITRA-HEAT, Nuheat, SunTouch, WarmlyYours, QuietWarmth), including GFCI-protected circuits, programmable and smart thermostats, multi-zone controls, and floor sensor wire installation.

Electric Vehicle Pre-Wiring for New Construction

Building a new home or developing a property? California now requires EV-ready wiring in new residential and commercial construction. We install EV pre-wire conduit and wiring during the rough-in phase — running a dedicated circuit from the panel to the garage or parking area so a Level 2 charger can be installed at any time without additional construction. This is far less expensive than retrofitting after the walls are closed up.

Troubleshooting & Diagnostic Services

Electrical problems don't always have obvious causes. Our electricians use professional diagnostic tools and techniques to track down and resolve complex issues: Common troubleshooting calls: partial power outages (some rooms have power, others don't), phantom loads and unexplained energy bills, voltage fluctuations and brown-outs, ground fault issues, arc fault tripping, intermittent circuit failures, neutral conductor problems, open ground and open neutral conditions, EMF concerns, stray voltage issues, circuit overloads, underground wire fault locating, rodent and pest damage to wiring, and water-damaged electrical systems. We use thermal imaging cameras, circuit tracers, megohm insulation testers, power quality analyzers, ground fault locators, and time-domain reflectometers to pinpoint issues accurately and efficiently.

Childproofing & Electrical Safety Upgrades

Protect your family with essential electrical safety upgrades: tamper-resistant receptacles (TRR) throughout the home (required by NEC in all new and renovated locations), GFCI outlets in all wet locations, AFCI breakers for bedrooms and living spaces, outlet covers and child-safe plates, cord management and concealment, heavy appliance anchoring and cord routing, and whole-house safety inspections focused on child-accessible hazards.
