01
Transfer switches
A transfer switch keeps a generator from back-feeding the utility line. Both manual and automatic versions are available.
02
Choosing what stays on
HAXX helps pick the circuits that matter most, such as the refrigerator, well or sump pumps, furnace blower, lights and internet.
03
Permits and placement
Generator wiring needs an electrical permit. HAXX applies through the Town and plans placement for exhaust clearance and noise.

★★★★★
“The technician from Haxx immediately pointed out multiple violations of the National Electrical Code and explained that the wiring was overheating and could potentially become a fire hazard. They offered to redo the installation the correct way, pulled the proper permit, and installed the EV charger safely and professionally. The city inspection passed without any issues.”
★★★★★
“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!”

GOOD TO KNOW
Generator Installation in Danville: questions, answered.
Does PG&E shut off power near Danville?
Yes. PG&E has used Public Safety Power Shutoffs in areas around Danville, including Camino Tassajara. Sign up for PG&E alerts for your address.
Can a portable generator connect to my panel?
Only through a transfer switch or approved interlock. HAXX installs these so a portable unit can run selected circuits 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.
