What it is

What a dedicated circuit does

A dedicated circuit is a wire run from the panel that feeds one appliance or one area. It stops a big load from sharing, and tripping, a circuit with other devices.

  • Heat pumps and ductless mini-splits
  • Kitchen appliances, ranges and microwaves
  • Home offices with computers and space heaters
  • EV chargers in garages and carports
  • Shops, sheds and detached garages

What the contractor checks

  • Open breaker spaces and panel capacity
  • Wire size and breaker size for the load
  • GFCI and arc-fault needs for the location
  • The cable route through crawl space or attic

Olympia rules

Permits and local wiring rules

New circuits inside city limits need a City of Olympia electrical permit, at 601 4th Ave E. The City's code adds local rules, such as metal wiring methods in the Downtown Business and Urban Waterfront zones.

A circuit is also the first step for backup power. A generator installation needs a transfer switch and the right circuits on it.

Before you call

  • What the circuit will power, with its nameplate
  • Distance from the panel
  • A photo of the panel

Garages and shops

Circuits for garages, shops and outbuildings

Detached garages and shops are common on larger Olympia lots. Powering one usually means a feeder from the house panel to a small subpanel in the building.

The cable or conduit runs underground at a depth set by the code, and the outbuilding needs its own grounding. Damp garages need GFCI protection on outlets.

Shop tools, compressors and welders each have their own needs. Share the nameplates so the contractor can size the feeder and the circuits.

Planning list

  • Distance from the house panel
  • Tools and heaters you will run
  • Lighting needs
  • Whether you want EV charging there

Do I need a permit for a new circuit in Olympia?

Yes, for most new circuits inside city limits. The contractor applies to the City and schedules the inspection.

What if my panel is full?

The contractor may add tandem breakers where allowed, add a subpanel, or recommend a panel upgrade. A load calculation guides the choice.

Does a heat pump need its own circuit?

Yes. Heat pumps and mini-splits run on their own circuit sized to the unit's nameplate.
