Permanently installed generators that start automatically when the power goes out.
An outdoor inlet and interlock or transfer switch, so a portable generator can power selected circuits without extension cords.
Manual or automatic transfer equipment sized to the generator and the loads you want to keep on.
Fridge, furnace blower, internet, lights and medical equipment moved to a backed-up subpanel.
Generator size matched to what you actually need to run, not guesswork.
Electrical permit, city inspection and utility requirements handled by HAXX.
Wind and winter storms can drop power lines on tree-lined streets. Home offices, medical equipment, sump pumps and refrigeration are the usual reasons to plan backup.
A listed inlet with a panel interlock lets a portable generator power chosen circuits safely.
Automatic generators with a transfer switch start on their own and are sized to the loads you choose.
HAXX plans location for clearance and noise and files the City of Los Altos permit.

“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”
“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”

No. A generator must connect through a transfer switch or a listed inlet with an interlock; back-feeding endangers you and utility line crews.
That comes down to the circuits you want covered. A load calculation tells HAXX the right size.
No. Back-feeding through an outlet is dangerous for you and for utility workers. Use an inlet with an interlock or a transfer switch.
It depends on the circuits you want to keep powered. HAXX lists your critical loads and sizes the generator to them.
