Reliance Installation and Operating Instructions
Key Components of the Reliance Transfer Switch
Figure 1
Circuit breakers. Each transfer switch circuit has a 1-in interchangeable circuit breaker
that protects the branch circuit when the circuit selector switch is in the GEN position. In
the LINE position, each branch circuit is protected by the breaker in the load center.
Circuit selector switches. These switches allow you to select either GEN (generator) or
LINE (utility) as the power source for the branch circuits that have been wired through the
transfer switch. The OFF position is generally not used, as a switch in the OFF position
removes that branch circuit from both utility and generator power.
Handle ties. Handle ties are used for 240-volt circuits or multi-wire branch circuits. They
may be removed for 120-volt circuits. See page 6 for instructions on removing and adding
handle ties.
Power inlet filler plate. This can be replaced with a power inlet that is included in the
suffix A and B models (see page 7 for installation instructions). The power cord from the
generator is plugged into this inlet. The inlet is supplied separately for indoor models to
encourage the use of a remote connection outdoors reducing the likelihood of running the
generator indoors which is extremely dangerous. If this indoor model is installed outdoors,
make sure it is installed in a dry location.
Circuit Breaker Compartment Cover. Remove to change circuit breakers. Also includes
a wiring space that can be used to hard-wire the unit to a remote power inlet box.
Analog wattmeters (suffix A and C models). These meters indicate the total load, in
watts, on each side of the generator when the generator is supplying power as follows:
The left meter measures the load on
A, C, and E
A,C,E, and G
A, C, E, G and I
Note: The watt meters will register only if power is being used from the generator.
