When You Need a New Electrical Panel Installation

New Construction Electrical Panel Installation

Building a new home, addition, or detached structure? You need a properly sized main electrical panel that meets current California Title 24 and NEC code requirements. We install panels for new construction projects from start to finish, including coordination with SCE for new service.

ADU Panel Installation

Accessory Dwelling Units require dedicated electrical capacity. We install ADU panels and subpanels that can be metered separately for rental properties or share existing service for family use. Code-compliant installation with capacity for modern appliances. Combine with our electrical panel upgrade services if your existing main panel needs more capacity to support the ADU.

Garage & Workshop Subpanels

Add a 50-amp or 60-amp subpanel to your garage or workshop for EV charging, power tools, welders, or workshop equipment. Subpanels eliminate the need for long extension cords and prevent overloading your main electrical panel. If your main panel is older or undersized, you may need an electrical panel upgrade before adding a subpanel.

Pool, Hot Tub & Outdoor Subpanels

Outdoor-rated subpanels for pool equipment, hot tubs, detached workshops, and outdoor kitchens. Code-compliant installation with weatherproof enclosures and proper bonding for wet locations.

Types of Electrical Panel Installation We Provide

Main Panel Installation

Complete main electrical panel installation for new construction. Includes service entrance conductors, weatherhead, meter base, grounding, and bonding. We coordinate with SCE for new service connection and handle all required permits and inspections.

Subpanel Installation

Add a subpanel to extend electrical service to a specific area of your home. Common uses include garage subpanels (50-amp or 60-amp), workshop subpanels, ADU subpanels, pool equipment subpanels, and outdoor kitchen subpanels.

Service Entrance Installation

Install or relocate the service entrance — the connection point between SCE's power lines and your electrical system. Includes weatherhead, meter base, and main disconnect. Required for new construction or major service relocations.

Subpanel Installation for Garages, ADUs & Workshops

A subpanel is a smaller electrical panel that distributes power to a specific area of your home or property. Subpanels are ideal for adding electrical capacity to garages, workshops, ADUs, pool equipment areas, and EV charging stations without overloading your main electrical panel.

01

Garage Subpanels

A 50-amp or 60-amp subpanel for your garage gives you dedicated capacity for EV charging, power tools, air compressors, welders, and workshop equipment. Eliminates the need for long extension cords running from your main panel and prevents overloading.

02

ADU Electrical Subpanels

A separate subpanel for your ADU simplifies electrical management, allows independent metering for rentals, and ensures your ADU has the capacity for modern appliances. Required by some California cities for new ADU construction.

03

Outdoor & Pool Subpanels

Outdoor-rated subpanels for pool equipment, hot tubs, detached workshops, and outdoor kitchens. Code-compliant installation with weatherproof NEMA-rated enclosures and proper bonding for wet location safety.
