Product FAQs
5 answersWhich load centers accept the Zinsco HRGF15 circuit breaker?
The HRGF15 is a plug-in breaker designed specifically for legacy Zinsco load centers. It is also compatible with certain older Sylvania and GTE panels that were manufactured to accept Zinsco-style breakers.
How do I wire the pigtail neutral on the HRGF15?
The white pigtail wire attached to the breaker must be connected directly to the panel's neutral bus bar. The neutral wire from the branch circuit connects to the designated neutral terminal on the breaker itself to ensure proper ground fault detection.
Can the HRGF15 be used on a multi-wire branch circuit with a shared neutral?
No. Single-pole GFCI breakers require a dedicated neutral for the circuit they protect. The branch circuit neutral must connect directly to the breaker to accurately monitor for ground faults. Sharing a neutral will cause the breaker to trip immediately.
Are the trip settings on the HRGF15 adjustable?
No, the thermal-magnetic trip unit features fixed long-time, instantaneous, and ground fault trip settings.
Is the HRGF15 an exact replacement for older Zinsco GFCI breakers?
Yes, the HRGF15 is the direct replacement for legacy 15A, 1-pole Zinsco ground fault breakers. It maintains the original plug-in mounting style required to connect to Zinsco bus bars.
