Circuit Test Instructions
Use the instructions below to test the relay modules. The setup requires:
–
20 Amp Dual Relay Companion Module.
–
(2) loads (20 amps max for each).
–
(2) 20 amp circuit breakers.
–
Breaker test panel. The type of module determines the type of breaker panel (plug-on neutral or not).
–
120V AC source
1. Plug the two feeder circuit breakers and one 20 Amp Dual Relay Companion Module into the circuit breaker test panel.
2. Connect the output from one of the circuit breakers to Input A
on the module.
3. Connect the output from the remaining circuit breaker to Input
B on the module.
4. Connect a load to Output A.
5. Connect a second load to Output B.
6. Connect the unused side of each load to the neutral bus bar in
the breaker panel.
7. On modules that contain a neutral wire, connect the neutral
wire to the neutral bar.
8. Apply power to the breaker panel (not shown in diagram).
9. Toggle the 20 amp feeder breakers to On.
10. To test, toggle the CIRCUIT POWER switches A and B to ON
and verify both loads switch On.
11. Toggle the CIRCUIT POWER switches to AUTO and verify the
loads switch Off

–
When making connections, observe all general electrical best practices including local wire sizing guidelines.
–
The GPM-CP2R20120-21 and GPM-C2R20120-21 modules can accept up to a #12 AWG wire. See the
Branch Circuit Minimum Size of
Conductors
table on the previous page for wire sizing information.
