Product FAQs

5 answers
Can I install the Murray MP115GF in a Siemens load center?

Yes. Siemens acquired the Murray brand and officially lists Murray MP series breakers as interchangeable with Siemens QP series panels. This breaker is compatible with both legacy Murray and Siemens load centers.

What is the Siemens cross-reference for the Murray MP115GF?

The Siemens QF115A is the direct replacement for the MP115GF. Following Siemens' acquisition and phase-out of the Murray brand, the QF115A serves as the official substitute, offering the same Class A ground fault protection and panel compatibility.

What level of ground fault protection does the MP115GF provide?

This breaker provides Class A ground fault protection. It is designed to trip when a ground fault exceeds the 5mA threshold, meeting NEC requirements for personnel protection in wet or damp locations.

How is the neutral connection wired on this GFCI breaker?

The MP115GF features a standard pigtail neutral. The attached coiled white wire must be connected directly to the neutral bus bar in your load center, while the circuit neutral connects to the breaker itself.

Is the MP115GF suitable for HVAC equipment?

Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 15-amp, 120-volt circuit.
