USING THE RELIANCE TRANSFER SWITCH WITH A GENERATOR
THIS RELIANCE TRANSFER SWITCH IS NOT FOR "DO-IT-YOURSELF" INSTALLATION. Installer must be
thoroughly familiar with electrical wiring systems. This Reliance Transfer Switch is designed to provide, in the
event of a utility power outage, a safe and simple method of powering a single 250 volt circuit, or two 125 volt
circuits simultaneously, from a portable generator with a combination 125/250 VAC output. The DPDT selector
switch will feed the circuit load(s) from either the utility or the generator, and prevent backfeeding of one source

from another.

KEY COMPONENTS OF THE TRANSFER SWITCH

SELECTOR SWITCH. Selects either "LINE" (utility) or "GEN" (generator) as the source feeding the circuit
load(s).
POWER INLET. NEMA L14-20 configuration. Inputs power from the portable generator.

TRANSFERRING FROM UTILITY POWER TO GENERATOR POWER

1. Move the selector switch handle to the "OFF" or “LINE” position.

2. Insert the male power cord plug into the appropriate outlet on the generator. If locking receptacle is used,

rotate to lock.

3. Insert the female power cord connector into the power inlet located on the lower face of the transfer switch.

Rotate to lock.

4. Start the generator, following the procedures described in the generator owner's manual furnished by the

generator manufacturer.

5. Move the selector switch knob to the "GEN" position to energize load from generator.

TRANSFER RING FROM GENERATOR POWER BACK TO UTILITY POWER
