Does a QO250GFI require a load neutral connection?
Applies to QO-GFI, 50A and below
A load neutral connection is required only if there is a load neutral. The circuit breaker will perform properly without a load neutral on a 2-wire 240Vac circuit. However the neutral pigtail still has to be connected to panel neutral bar.
For more information on wiring please see instruction bulletin 48840-435-03 in our technical library.
