2–9 Defeatable Ground Fault
Rating plugs with the suffix “GFD” appended to the
catalog number have the additional setting
OFF on the
Pickup switch, which defeats ground-fault protection.
These rating plugs are not UL listed. An interlock
mechanism prevents their insertion into Trip Units
designed for non-WavePro breakers.
