Backup Power: Generators & Transfer Switches

Pacific Northwest storms don’t wait for a convenient time to knock out your power. Arcline Electric installs whole-home generator systems that keep your lights on automatically.

Whole-Home Backup Power for the Pacific Northwest

The Greater Seattle and Puget Sound region experiences some of the most unpredictable weather in the country. Atmospheric river events, high-wind storms, ice accumulation, and fallen trees regularly knock out power to tens of thousands of homes, sometimes for days. Extended outages during winter months create cascading problems: frozen pipes, spoiled food, sump pump failures, loss of heating, and disrupted work-from-home schedules.


A whole-home standby generator eliminates all of these risks. Unlike portable generators that require manual setup and extension cords, a permanently installed standby unit connects to your natural gas or propane supply and monitors utility power 24 hours a day. When grid power fails, the automatic transfer switch detects the loss within seconds, starts the generator, and transfers your home’s electrical load automatically. The entire switchover typically takes less than 30 seconds.

Automatic Operation

The ATS starts your generator and transfers power within seconds of an outage. No manual intervention, no fumbling in the dark.

Proper Sizing

We perform detailed load calculations to recommend the right generator size. No undersized units that overload, no oversized units that waste fuel.

Generator mounting, transfer switch, electrical connections, gas line coordination, permits, and inspection. One point of contact for everything.

Generator Reviews

What Our Backup Power Customers Say

"We had Arcline install a Generac whole-home generator with automatic transfer switch. Living in Lake Stevens, we lose power a few times each winter. Now the lights don't even flicker. The install was clean, permitted, and they walked us through the maintenance schedule."

Robert P.

Lake Stevens, WA | 22kW Generac Install

"After the ice storm last winter knocked our power out for three days, we decided enough was enough. Arcline installed a Kohler 20kW generator with an automatic transfer switch. The whole project was handled turnkey. They even coordinated the gas line work with our plumber."
