1.2 BACKGROUND
Transfer switches are used to protect critical electrical
loads against loss of power. The load’s normal power
source is backed up by a secondary (emergency) power
source. A transfer switch is connected to both the nor-
mal and emergency sources and supplies the load with
power from one of these two sources. In the event that
power is lost from the normal source, the transfer switch
transfers the load to the secondary source. Transfer can
be automatic or manual, depending upon the type of
transfer switch equipment being used. Once normal
power is restored, the load is transferred back to the
normal power source.
In automatic transfer switch equipment, the switch’s
intelligence system initiates the transfer when normal
power fails or falls below a preset voltage. If the emer-
gency source is a standby generator, the transfer switch
initiates generator starting and transfers to the emer-
gency source when sufficient generator voltage is avail-
able. When normal power is restored, the transfer
switch automatically transfers back and initiates engine
shutdown.
