Serving high-demand 120V applications, this 30-amp single-pole GFCI ensures critical 5mA Class A protection against electrical shocks. It provides a seamless hardware solution for maintaining older infrastructure without requiring panel upgrades. The unit installs easily into legacy Murray and Siemens load centers, acting as a reliable alternative to the QF130A. Featuring a standard pigtail neutral wire and self-testing capabilities, it maintains rigorous safety compliance.
Can I install the Murray MP130GF in a Siemens load center?
Yes. Siemens acquired the Murray brand, and the MP130GF is UL listed for use in both Murray and Siemens load centers that accept plug-on breakers. Always verify your specific panel label for approved breaker types.
What level of ground fault protection does the MP130GF provide?
This breaker provides Class A ground fault protection, which is designed to trip when a ground fault of 5mA is detected. This protects personnel from electrical shock in wet or damp locations.
How do I connect the neutral on the MP130GF?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the neutral bus bar in your load center to ensure the ground fault circuitry functions correctly. The load neutral connects to the breaker itself.
What is the Siemens equivalent to the Murray MP130GF?
The direct Siemens equivalent is the QF130 or QF130A. Because Siemens manufactures both lines, they share the same physical design and thermal magnetic trip functions for 30-amp, 1-pole GFCI applications.
Can I use this 30A GFCI breaker for a 240V circuit?
No. The MP130GF is a 1-pole breaker rated for 120V AC only. For a 240V application requiring ground fault protection, you will need a 2-pole GFCI breaker.
Does this breaker require a separate ground wire connection to the breaker itself?
No. The equipment grounding conductor from your branch circuit connects to the ground bus bar in the panel, not the breaker. The breaker only requires the ungrounded hot wire, the load neutral, and the pigtail neutral connection to the panel neutral bus.
