Sub Panel Installation in Rutherford, CA
Whether you are converting a garage, building an accessory dwelling unit, or finally wiring the shop behind the house, a sub panel is the clean way to do it. Our electricians design and install sub panels for Rutherford homeowners and small businesses throughout Napa County.
Sub Panel Installation services we provide in Rutherford
- Garage and detached workshop sub panels
- ADU and guest house electrical panels
- Pool, spa and outdoor equipment panels
- Sub panels for home additions and remodels
- Underground and overhead feeder installation
- Trenching coordination for detached buildings
- Circuit relocation from a full main panel
- Load calculations and permit handling
Each sub panel project in Rutherford starts with a load calculation to confirm the main service can support the new panel. We then run a properly sized feeder, install the sub panel with its own breakers, bond and ground it correctly, and label everything. The result is a clean, expandable panel that passes inspection the first time.
We have installed sub panels for garages, ADUs and shops in Rutherford and neighboring Oakville, Saint Helena and Yountville. If your main panel is already full, we can also discuss whether a panel upgrade should be paired with the sub panel so you are not back at capacity next year.
A sub panel makes sense in Rutherford when
- You are building or converting an ADU or garage
- The main panel has no open breaker spaces
- You need several new circuits in one area
- You are adding a shop with 240-volt tools
- Pool or spa equipment needs its own feed

What Rutherford customers say
★★★★★Generator install with an automatic transfer switch. First shutoff after the install, the lights flicked and came right back. Everyone in Rutherford should have one of these.
★★★★★Whole house surge protector and a new outdoor outlet. Quick visit, fair flat rate, and the electrician took the time to check our grounding too.
★★★★★We needed a Tesla charger installed before our car arrived. They handled the permit, ran the circuit cleanly through the garage and tested everything with the car. Highly recommend in Rutherford.
