Issue:
Application on 3w system
Product Line:
Panelboards
Environment:
NF
Cause:
Use 4w panel on a different voltage
Resolution:
Yes, ONLY if the panel is being fed from a 480Y/277 V system upstream and they are simply not pulling the neutral conductor to the NF interior. 2 pole and 3 pole breakers can be used.
Note: The NF panel CANNOT be used on a 3ph, 3w delta system. The EDB or similar branch breakers are not rated for 480 V to ground.
