How can we help you today?
Can a GFM150HD or GFM250JD be operated on a 3w system without a neutral, and how is it wired?
Issue:
Using Ground Fault Module

Product Line:
Ground Fault Equipment

Resolution:
Yes, it can be operated on a 3w system, provided the system is grounded.

On this system, the neutral CT is not required, therefore leave terminals 5 and 6 open. Do not jumper terminals 5 and 6.
