(833) 652-8933 Request a quotePublic Safety Power Shutoffs, wildfire season and winter storms make backup power a practical need in Annapolis. Phasethree Electric installs whole house standby generators, Generac and Kohler systems, automatic transfer switches and manual transfer switches with portable generator inlets for homes and small businesses in Annapolis and across Sonoma County.
We size the generator to your real loads, pour or set the pad, run the electrical connection to a transfer switch at your panel, coordinate the gas or propane connection, pull the permit and start up and test the unit. Automatic units start within seconds of an outage.
If a full standby system is more than you need, a manual transfer switch and outdoor inlet lets you safely power selected circuits from a portable generator without extension cords through windows.
We also service and repair existing generators, replace batteries, and add load management modules so a smaller unit can run more of the house. Call (833) 652-8933 for Annapolis and nearby Stewarts Point, The Sea Ranch, Cazadero, Yorkville.
We provide generator installation throughout Annapolis and the surrounding communities of Sonoma County.
Most homes need 14 to 26 kW for whole house coverage. We run a load calculation so you are not overpaying.
Electrical work is usually one day. Total time depends on gas connection and permit scheduling in Annapolis.
Yes, an annual service with oil, filter and a load test keeps the warranty valid and the unit reliable.
“Called at 11pm with sparks from a bathroom outlet. Someone was here within the hour and made it safe, then came back in the morning to finish.”
Priya S.“Smart switches finally work because they added neutrals at every box. Should have called them first instead of trying myself.”
Nina P.“Quoted me a firm price for recessed lighting in the kitchen and living room and the invoice matched to the dollar. Lights look fantastic.”
