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

- Load calculations and permit handling
Each sub panel project in Fullerton 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 Fullerton and neighboring Placentia, Brea and Atwood. 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 Fullerton 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

★★★★★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.

★★★★★Our restaurant lost power to the walk-in on a Saturday night. They came out fast, replaced a failed breaker and got us reopened. Saved a lot of food and a lot of stress.
