Subpanel Installation

Power your shop, garage, ADU or outbuilding properly with a professionally installed electrical subpanel. We size the feeder, set the panel, handle trenching and grounding, and pull the permits — clean, code-compliant power exactly where you need it.

Subpanel Installation in Auburn

When one panel can’t do it all, a subpanel brings power where you need it — the shop, the garage, the ADU, the barn. We install subpanels throughout Auburn and Placer County: properly fed, properly grounded, permitted and inspected.

Where Subpanels Make Sense

  • Detached garages & workshops: Welders, compressors, dust collection and lighting on their own panel — no more tripping the house breaker from the shop.
  • ADUs & additions: A subpanel is usually the cleanest way to power an accessory dwelling or major addition.
  • Hot tubs, pools & outdoor living: Local distribution for big backyard loads.
  • EV charging: A garage subpanel creates room for one or two EV charger circuits when the main panel is full.
  • Well houses & outbuildings: Safe, code-compliant power for rural property infrastructure.

What a Professional Subpanel Install Includes

  • Load calculation & feeder sizing: The feeder breaker, conductors and panel rated for what you’ll actually run (60A and 100A are the common choices).
  • Correct grounding: Separated neutrals and grounds, plus a grounding electrode at detached buildings — the details DIY installs get wrong most often.
  • Trenching & conduit for detached structures, done at code depth.
  • Clean breaker layout with labeling, room to grow and AFCI/GFCI protection where required.
  • Permits & inspection with Placer County or the City of Auburn.

Subpanel or Main Panel Upgrade?

A subpanel adds distribution; it doesn’t add capacity. If your main service is already maxed out — a 100A panel feeding a modern all-electric household — a subpanel alone won’t fix nuisance trips. In that case a main panel upgrade (often to 200A) is the right first move, and we’ll show you the load math that says so. Frequently the best answer is both: upgrade the service, then distribute it where life actually happens.

Frequently Asked Questions

  • 60 amp or 100 amp subpanel? For a shop with serious equipment or an ADU, 100A future-proofs for a modest cost difference. For lighter loads, 60A is often plenty. The load calc decides.
  • How far can a subpanel be from the main? Practically any distance — conductor sizing accounts for voltage drop on long runs to barns and outbuildings.
  • Can I just add breakers to my main panel instead? If space and capacity allow, yes — and we’ll say so. A subpanel earns its cost when the panel is full, the loads are remote, or a structure needs its own disconnect.
  • Does a subpanel require a permit? Yes — and unpermitted panels are a common escrow problem when selling. We permit everything.
