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

★★★★★Rewired our 1950s house. I expected a disaster and instead they kept our bedrooms and kitchen running the whole time. Small holes, all patched. Worth every dollar.
