Equipment Description
The transfer switches are intended to transfer the entire
load of normal residential installations when used with the
supervisory contacts provided.The load is connected either
to utility power (normal) or home standby power
(generator).The transfer switch monitors utility and
generator voltages and will automatically connect to the
appropriate source of power.
Major components of the transfer switch are a 2 pole
disconnect circuit breaker (models 01928-1 & 01929-1
only), a 2 pole double throw transfer switch,control circuit
board, fused utility terminals and interconnecting wiring.
The transfer switch is solenoid-operated from utility or
generator inputs and contain suitable mechanical and
electrical interlock switches to eliminate the possibility of
connecting the utility service to the generator output. It
has ratings capable of switching full utility power into the
residence. In addition, a manual override lever is provided
for the transfer function.
The control circuit board has active circuits sensing utility
and generator voltages. It creates a signal for the generator
start-up, switch transfer, retransfer when utility is restored
and generator cool down periods.The control board also
contains red and green LED’s indicating the power sources
available and two relay operated contacts that provide
supervisory control of external loads.
