Sub Panel Installation in San Pedro, CA
A sub panel lets a San Pedro property add a workshop, ADU, pool equipment or garage EV charger without crowding the main panel. Unique Electrical Services installs sub panels in San Pedro, CA with correctly sized feeders, separate grounds and neutrals, and enough spare capacity for what comes next.
Sub Panel Installation services we provide in San Pedro
- Garage and detached workshop sub panels
- ADU and guest house electrical panels

Each sub panel project in San Pedro 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 San Pedro and neighboring Wilmington, Lomita and Harbor City. 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 San Pedro 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
