On service calls across Bellevue, we see the same failure patterns again and again: generators sized for a 1990s panel that can't handle a home with a heat pump and EV charger added later, transfer switches wired into aging subpanels never meant for automatic switching, and units installed too close to crawl space vents that draw exhaust back into the house. Getting the sizing and placement right up front avoids callbacks during the next outage.
Local knowledge
What's different about generator installation in Bellevue
Every area we serve is different — in Bellevue, these three factors matter most.
Bellevue neighborhoods like Somerset, Newport Hills, and West Bellevue sit under mature tree canopy, and PSE outages from falling limbs during winter windstorms are the top reason homeowners here call us for backup power.
Many homes in the Enatai and Lake Hills areas were built in the 1960s-70s with 100-amp service that's since been upgraded piecemeal, so we often find the existing panel can't support a generator transfer switch without an upgrade first.
Newer Bel-Red corridor homes with heat pumps, induction ranges, and EV chargers pull more continuous load, which means a 14kW unit that would cover an older Bellevue rambler often falls short here and needs to be sized up.

No surprises
How a Bellevue generator installation visit works
1
Load calculation and site visit
We walk the property, review your panel and main breaker size, and calculate what circuits you actually need to run so the generator isn't oversized or underpowered.
2
Permit and utility coordination
We pull the required King County or City of Bellevue electrical permit and coordinate any PSE gas or electric service questions before work starts.
3
Pad setup and generator placement
We set the concrete pad or mounting bracket at least the required clearance from windows, doors, and vents per code, factoring in Bellevue's drainage and slope conditions common on hillside lots.
4
Electrical and gas connection
Our electricians install the transfer switch, run conduit to the main panel, and connect gas or propane lines, verifying the existing panel can handle the added load without a separate upgrade.
5
Startup, testing, and inspection
We run the unit through a full transfer test, walk you through the automatic weekly self-test schedule, and schedule the final inspection so everything's signed off.

Straight answers
Generator Installation in Bellevue — FAQ
How long does generator installation take in Bellevue?
Most installations take one to two days for the electrical and mechanical work, but total project time depends on how quickly the City of Bellevue processes the electrical permit, which typically adds one to three weeks before we can schedule the install date.
Do I need a permit for a standby generator in Bellevue?
Yes, standby generators require an electrical permit and inspection through the City of Bellevue. We handle the permit application and schedule the inspection as part of the installation, so you don't have to deal with the paperwork.
Will a generator run my whole house during a PSE outage?
It depends on size. A properly sized whole-home unit will run everything including HVAC and a heat pump, while a smaller unit covers essential circuits like the fridge, well pump if you have one, and a few outlets. We size it based on your actual panel load, not a generic estimate.
Why did my old generator fail during the last windstorm outage?
The most common issue we find on Bellevue service calls is a dead or corroded battery from lack of monthly maintenance, followed by transfer switches wired into panels that were never upgraded to handle automatic switching. Both are preventable with a proper install and a basic annual check.
