Subpanel Installation & Repair in San Diego

Sometimes the right answer isn't a whole new main panel — it's a subpanel. Feeding a garage, an ADU, a backyard studio, a workshop, or a big EV charger from a subpanel keeps your main panel intact and adds exactly the capacity you need where you need it.

When a subpanel makes sense

  • Adding a level-2 EV charger and you don't want to run the circuit through the whole house
  • Building or converting an ADU with its own load
  • Detached garage or workshop needing lighting, outlets, and a 240V circuit
  • Home addition where running new circuits back to the main is impractical
  • Pool equipment, spa, or outdoor kitchen area

What we handle

Sizing the subpanel to the load, sizing the feeder correctly, running the feeder in conduit or as SER cable through the appropriate path, installing the subpanel with proper grounding and bonding (neutrals and grounds separated at the subpanel, per code), pulling the permit, and scheduling the inspection.

Questions we get about this service

Do subpanels need their own ground rod?
It depends. A subpanel in a separate structure (like a detached garage) typically needs its own grounding electrode. A subpanel in the same structure as the main runs its equipment ground back to the main.
What size subpanel do I need?
Depends on load. A single EV charger might need a 60-amp subpanel; a detached ADU could need 100 amps. We do the load calc on the estimate.
