SECTION 7: MAINTENANCE
7.1 INTRODUCTION
HIGH VOLTAGES ARE PRESENT IN AND AROUND
TRANSFER SWITCH EQUIPMENT. BEFORE
INSPECTING OR MAINTAINING THIS EQUIPMENT,
DISCONNECT LINE POWER FROM THE EQUIPMENT
BEING SERVICED BY OPENING AND LOCKING
OUT, IF POSSIBLE, THE NEXT HIGHEST DISCON-
NECT DEVICE. FAILURE TO FOLLOW THIS PROCE-
DURE COULD CAUSE PERSONAL INJURY AND/OR
DEATH.
In general, transfer switch equipment is designed to be
relatively maintenance free under normal usage.
However, because of the variability of application condi-
tions and the importance placed on dependable opera-
tion by this type of equipment, inspection and mainte-
nance checks should be made on a regularly scheduled
basis. Since equipment maintenance will consist mainly
of keeping the equipment clean, the frequency of main-
tenance will depend, to a large extent, on the cleanli-
ness of the surroundings. If a significant amount of dust
or foreign matter is present, a more frequent mainte-
nance schedule should be followed.
It is suggested that visual inspections of the equipment
be made on a regular basis, not just during regularly
scheduled periods. Always be alert for an accumulation
of dirt in and around the structure, loose parts and/or
hardware, cracks and/or discoloration to insulation, and
damaged or discolored components.
Figures 7-1 is the wiring diagram for the residential
automatic transfer switch. Only qualified and experi-
enced personnel should attempt any diagnostic work
using this diagram.
7.2 PROCEDURES
A suggested maintenance procedure to follow is out-
lined in Table 7.1.
