Maintenance
The transfer switch is designed to be maintenance free under
normal usage. However, inspection and maintenance checks
should be made on a regular basis. Maintenance will consist
mainly of keeping the transfer switch clean.
Visual inspections should be done at least once a month.
Access to transfer switch must not be obstructed. Keep
3 feet (92 cm) clearance around transfer switch. Check
for an accumulation of dirt, moisture and/or corrosion
on and around the enclosure, loose parts/hardware,
cracks and/or discoloration to insulation, and damaged or
discolored components.
Exercise the transfer switch at least once every three months
as described in Testing the Automatic Transfer Switch unless
a power outage occurs and home generator system has gone
through an automatic sequence. Allow generator to run for at
least 30 minutes.
Contact a licensed electrical professional to inspect and clean
the inside of the enclosure and other components of your
home generator system at least once a year.
