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 (1 m) 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 section 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 your transfer switch at least once a year.
