What it is
Standby generators and portable hookups
Generator installation is the wiring of a backup generator to a home through a transfer switch or interlock. The switch keeps generator power off PSE lines, which protects line crews.
- Standby generator: fixed unit outside, starts on its own when power fails.
- Portable hookup: an inlet box and interlock or transfer switch for a portable generator.
- Load choice: whole house, or selected circuits such as furnace, fridge, well pump and lights.
Why Olympia owners add one
Windstorms push trees into lines across Thurston County. On April 4, 2022, winds cut power to thousands from northeast Olympia to Lacey. Homes with sump pumps, well pumps or medical equipment feel these outages first.
Planning
What the install involves
- Pick the loads you need during an outage.
- Size the generator to those loads.
- Choose a transfer switch or interlock.
- Get the City of Olympia electrical permit.
- Install, inspect and test.
Some homes need new circuit installation first, so key loads can be grouped on the generator side.
Safety rules
- Never backfeed through a wall outlet
- Keep portable units outside, away from doors and windows
- Natural gas or propane units may need a separate gas permit
Fuel and placement
Choosing fuel and a location
Standby generators in the area usually run on natural gas or propane. Gas lines and tanks have their own rules and permits, so the electrical contractor and the gas installer plan together.
The unit sits outside on a pad, with clearance from windows, doors and vents set by the maker. Placement also affects noise for you and your neighbors.
Portable generators are a lower-cost option. An inlet box on the outside wall and an interlock on the panel let you run chosen circuits safely from a cord.
Loads people pick
- Furnace or heat pump air handler

Generator Installation in Olympia: FAQs
Talk to a licensed electrician
Describe the problem and your ZIP. We will connect you with a local pro in Olympia.
Call (815) 456-4349Do I need a permit for a generator in Olympia?
Yes. Transfer switches, inlets and standby generators need a City of Olympia electrical permit for work inside city limits.
Can I plug my generator into a dryer outlet?
No. That backfeeds the home and PSE lines and can injure line workers. Use an interlock or transfer switch.
What size generator do I need?
It depends on what you want to run. The contractor adds up the loads and suggests a size.
