Ground Fault and Ground Continuity – Protection Panel GFGC

Procedure for wiring GFGC assembly into system
• Locate the wiring diagram specific to the line voltage. Be sure
to select the voltage and phase type specific to the point at
where the GFGC panel is connecting.
• Connect the incoming lines to the contactor, being sure to have
all phases going through the WN-35BS current transformer (in-
cluding the neutral if one exists).
Order of conductors is im-
portant
.
When connecting to the contactor, placement of the neutral is
important. Connect the outgoing lines in the same manner.
Do not pass the ground conductor through the current
transformer or connect it to the contactor!
• Connect the incoming and outgoing ground wires to the
ground lug.
• Locate the control transformer. Terminal 1 (“Com. H2”) should
already be connected. Connect it if it is not.
• Connect the other wire to the terminal specific to the line volt-
age being protected. For instance, if the system is a 208/120 V
system, and the GFGC assembly is connected on the 208 V por-
tion of the circuit, connect the wire to the terminal labeled
“208.”
• Connect the ground pilot wire clamp to the connector on the
outside of the enclosure.

Operation
The green POWER ON lamp illuminates when power is available to the load.
The red CIRCUIT TRIPPED lamp illuminates when power is removed from the load.
If unit has tripped, clear the fault and press Reset to resume operation.
Ground Fault Test
Unit must be tested at least once per month or before each use.
Press Test for >2 seconds. Unit must trip.
When unit trips a self test sequence starts. Wait >10 seconds.
Press Reset for >1 second. Unit should reset, restoring power to the load.
Ground Connection Monitor
Connect a pilot lead to the powered-equipment
ground and the connection located on the bottom of this enclosure. Loss
of this connection will cause loss of load power and the OPEN GROUND lamp to light.

1 -
Power ON light/Reset pushbutton
Light illuminates when power is received to the device and not
in an alarm state.
Pushing the button for > 1 second resets the device.
(Must wait for test to complete!)
2 -
Circuit tripped light/Test pushbutton
Light illuminates when the circuit has been tripped due to a
ground fault.
Pushing the button for > 2 seconds runs a test on the ground
fault detection unit.
3 -
Open ground light/Light test pushbutton
Light illuminates when the ground continuity monitor has
detected an open ground.
Pushing the button runs a test on the open ground light.
