Maintenance and Testing
A preventive maintenance program will insure high relia-
bility and long life for the transfer switch. A preventive
maintenance program should including the following:
Inspection and Cleaning
The switch should be inspected for any accumulation
of dust, dirt or moisture and should be cleaned by vacu-
uming or wiping with a dry cloth or soft brush. Do not
use a blower since debris may become lodged in the
electrical and mechanical components of the switch
and can potentially cause damage.
Remove the transfer switch barriers and check the
condition of the contacts. Any surface deposits must
be removed with a clean cloth (do not use emery cloth
or a file). Pitted or excessively worn contacts should be
replaced. General inspection of the general mechanical
integrity of the switch should be made to identify and
correct loose, broken or badly worn parts.
Servicing
All worn or inoperative parts must be replaced using
genuine GE recommended replacement parts. Contact
GE Technical Services for replacement parts information.
The operating mechanism of the transfer switch is
lubricated with Lubriplate 105. The lubricant applied
at the factory will provide adequate lubrication for the
lifetime of the switch. Should debris contaminate the
mechanism, clean and apply additional Lubriplate.
GE can provide complete preventative maintenance
services. For additional information contact GE Technical
Services at

Electrical testing of the switch is discussed in the “Testing”
section of this manual. A periodic test of the transfer
switch under load conditions is recommended to insure
proper operation. (See National Electric Code articles
700 and 701)
CAUTION
Due to hazardous voltages and currents, GE recommends
that a GE Certified technician or a qualified electrician
perform the installation and maintenance of the switch.
