I was looking at some Square D Combination AFCI circuit breakers and saw the 2-pole ones required a pigtail be ran from the breaker to the neutral busbar. They made some plug-on types but only single pole. Does this breaker require a pigtail to be ran to the neutral busbar? If not, is there a particular Murray 200-amp panel (around 40 spaces / circuits) this would work with? We're trying to find plug-on neutral type combination arc-fault breakers. We mainly need single pole 15-amp and 20-amp breakers but we will require a few double pole 30-amp and double pole 40-amp breakers as well. It's just hard trying to find the 2-pole ones that don't have the pigtail. Thanks!
Asked by: SporkSchivago
Hi SporkSchivago, Yes, this Murray two pole AFCI circuit breaker has a pig tail that will have to be connected to the neutral bar. I would recommend this Murray panel, but this breaker will work in any Murray panel you choose (40 space/40 circuit 200 Amp main): http://www.homedepot.com/p/Murray-200-Amp-40-Space-40-Circuit-Main-Breaker-Load-Center-LC4040B1200/202315562?keyword=LC4040B1200

Does this fit a panel with br type breakers?

Asked by: RG
Hi RG, This circuit breaker is only UL listed to be used in a Murray panel, check the wiring diagram on the inside of the panel cover for approved breakers.

Customer Reviews

20 Amp Double-Pole Type MP-AT Combination AFCI Circuit Breaker is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Murray 220v AFCI breaker meets all requirements Our county building codes adopted the requirement for AFCI breakers for branch circuits in bedrooms. Finding a 220 breaker for a Murray panel was difficult, but Home Depot on-line made it possible. Local electricians were somewhat concerned about AFCI working properly with heaters with fans, etc. But things are now working properly, and the job is complete and waiting for final inspections.
