EV Charger Installation in Washington

A Level 2 home charger needs a 240 volt circuit, usually 40 to 60 amps, run from your panel to the garage or driveway. The electrician checks whether your service can carry the load, pulls the permit and installs either a hardwired charger or a NEMA 14-50 outlet.

EV Charger Installation in Seattle, WA

Seattle has one of the highest rates of EV ownership in the country, but many homes in Ballard, Capitol Hill and Queen Anne have no garage, so chargers are often mounted outdoors by a driveway or carport, which requires an outdoor-rated unit and weatherproof wiring. Older homes may have 100 amp services already carrying electric heat or a heat pump, so a load calculation decides whether a 40 or 48 amp charger fits or a lower setting is better.

Utility: Seattle City Light

EV Charger Installation in Spokane, WA

Spokane's cold winters make garage charging especially useful for electric cars, since a warm garage helps range and battery life. Older homes on the South Hill and in Browne's Addition often have detached garages or alley parking, which means a longer run from the panel or an outdoor-rated charger.

Utility: Avista

EV Charger Installation in Tacoma, WA

Tacoma Power, the city-owned utility, has some of the lowest electricity rates in the region, which makes charging an electric car at home especially affordable. Older homes in the North Slope and Proctor often have detached garages or alley parking, so chargers may need a longer run or an outdoor-rated unit.

Utility: Tacoma Power (city-owned)

EV Charger Installation in Vancouver, WA

Vancouver has many EV owners who commute across the Columbia into Portland, and newer homes in east Vancouver usually have attached garages that make a Level 2 charger simple. Older homes in Hough, Arnada and Shumway may have detached garages or street parking, so an outdoor-rated charger or longer run may be needed.

Utility: Clark Public Utilities

EV Charger Installation in Olympia, WA

Olympia has many EV owners, and newer homes in the hills usually have attached garages that make a Level 2 charger simple, while older homes in Bigelow and South Capitol may have detached garages or street parking. Homes with electric heat or heat pumps may need a load calculation before adding a 40 or 48 amp charger.

Utility: Puget Sound Energy

Do I need a panel upgrade for an EV charger?

Not always. A load calculation shows whether the existing service can carry the charger; load management devices can avoid an upgrade in some homes.

Hardwired or plug-in charger?

Hardwired is often preferred for higher amperage and outdoor locations. A plug-in charger on a NEMA 14-50 outlet is easier to replace.
