DC-GFP-63 INSTALLATION

A DC-Ground Fault Protector is now required on all PV systems by the NEC 2008. The wiring

diagram below shows the GFP after the PV disconnect. It can also be placed prior to the

disconnect.

Cut out spaces to allow for the breaker assembly. Make sure the yellow snaps are totally snapped

onto the din rail. Torque to 20 inch pounds. Re-torque one hour later. Sometimes wires cold flow

and loosen up upon initial clamping.

If tripping occurs, check wiring carefully. More often than not, there is a wiring error.
