Backup power,
connected safely.
Standby generators and portable generator hookups installed with the right transfer equipment, so the house is powered safely and the utility line is never back-fed.
Portable generator inlets
An outdoor inlet and interlock or transfer switch, so a portable generator can power selected circuits without extension cords.
Transfer switches
Manual or automatic transfer equipment sized to the generator and the loads you want to keep on.
Critical-load panels
Fridge, furnace blower, internet, lights and medical equipment moved to a backed-up subpanel.
Load calculation
Generator size matched to what you actually need to run, not guesswork.
Permits and inspection
Electrical permit, city inspection and utility requirements handled by HAXX.
SAN JOSE DETAILSGenerators in
Generators in
San Jose.
Storms and grid problems can leave San Jose neighborhoods without power, and foothill areas near Almaden and Evergreen can be hit by wildfire-season shutoffs.
01
Foothill homes
Homes near the Almaden and Evergreen foothills are more exposed to storm damage and wildfire-season power shutoffs.
02
Home offices and medical needs
Many San Jose households need internet, a fridge or medical equipment to keep running. A critical-load panel covers that without a huge generator.
03
Safe hookups
An inlet with an interlock or transfer switch keeps a portable generator from back-feeding the PG&E line.

★★★★★
“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.”

GOOD TO KNOW
Generator Installation in San Jose: questions, answered.
Do I need a permit for a generator in San Jose?
Yes. Generator connections and transfer equipment need an electrical permit. HAXX files it and schedules the inspection.
Can you connect my portable generator?
Yes. HAXX installs an outdoor inlet with an interlock or transfer switch so selected circuits can run safely.
Can I plug a generator into an outlet?
No. Back-feeding through an outlet is dangerous for you and for utility workers. Use an inlet with an interlock or a transfer switch.
What size generator do I need?
It depends on the circuits you want to keep powered. HAXX lists your critical loads and sizes the generator to them.
