Can the ground fault pickup be disabled on a Micrologic 6.0A (ammeter), 6.0P (power), or 6.0H (harmonic) trip unit? Product Line:
Micrologic, Masterpact, Powerpact Resolution:
No. To eliminate ground fault protection, replace the trip unit with a 5.0 of the same type.
For ground fault alarm, replace the trip unit with a 5.0P or 5.0H trip unit and use an M2C (S64273) programmable contact module or I/O module(s) (LV434063).
Note: if ground needs to be temporarily disabled for primary injection testing, refer to FA98682
