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 the previous section Testing the Automatic
Transfer Switch
unless a power outage occurs and Home
Generator System has gone through 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.
