Product FAQs
5 answersWhat is the current Siemens replacement for the Murray MP220GF?
The Murray MP series has been phased out by the manufacturer. The official UL-listed replacement for the MP220GF is the Siemens QF220A.
Are Murray and Siemens circuit breakers interchangeable?
Yes. Siemens acquired the Murray brand and has issued official UL documentation confirming that Murray MP and Siemens QP style breakers are interchangeable and cross-listed for use in both Siemens and Murray load centers.
What class of ground fault protection does this breaker offer?
The MP220GF provides Class A ground fault protection. It is designed to trip when it detects a ground fault current of 5mA, meeting NEC requirements for personnel safety in areas like outdoor receptacles and pool pumps.
How do I connect the neutral on the MP220GF?
This breaker uses a pigtail neutral design. The coiled white wire attached to the breaker must be connected directly to the neutral bus bar in your panel to power the internal ground fault testing circuitry.
What type of overload protection does the LIG trip function provide?
The LIG code stands for Long-Time, Instantaneous, and Ground-Fault. This means the breaker combines standard thermal-magnetic protection for overloads and short circuits with integrated ground fault monitoring.
