Briggs & Stratton Power Products Manual Transfer Switch

Installation and Owner’s Manual

Equipment Description

These transfer switches are intended to operate compatible electrical loads of normal residential installations.The load is connected either to utility power (normal) or home standby power (emergency).

These manual transfer switches are equipped with two circuit breakers (“GENERATOR SUPPLY” and “UTILITY SUPPLY”) and a mechanical interlock.The “GENERATOR SUPPLY” circuit breaker provides power from the generator to the load devices wired to the manual transfer switch.The “UTILITY SUPPLY” circuit breaker provides utility power from the distribution panel to the load devices wired to the manual transfer switch.

The mechanical interlock allows the circuit breakers for either the generator power “GENERATOR SUPPLY” or the utility power “UTILITY SUPPLY” to be turned on to provide power to the selected house loads.These manual transfer switches will not allow utility line power and generator power to be connected to a load device at the same time.

If utility line power is restored while generator power is being used, there will be no affect on the generator or transfer switch components.When utility power is restored, follow the instructions in the section “System Operation”.

INSTALLATION
