Customer Questions & Answers

does a Square D circuit breaker fit into a Murray breaker panel?

Asked by: Ken
It may fit, but shoudn't be used. Square D circuit breakers are only UL Listed for use in Square D panels. To do so would be creating a code violation any good inspector will spot right away.

Number of Arc breakers required?

How many of these arc breakers are required, for a typical breaker box?
Asked by: SHAH
You need to consult the latest edition of NEC 210.12 for these requirements. You can also meet Code requirements with ARC fault and GFCI combinations on the same branch circuit. Consult a licensed electrician to be sure.

is the homeline 20 amp arc fault breaker a 30 milliamp interupting rating

Asked by: purchaser
You are confusing this arc fault breaker with a GFCI breaker for equipment protection. The combination arc fault breaker (CAFCI) protects against both parallel and series arcing faults.

Is this product rated for 100% continuous loads?

Asked by: Tom
No, this circuit breaker will handle up to 16 continuous amps. A continuous load is defined as 3 hours or longer continuously. If you have a continuous load over 16 amps the circuit is overloaded.

Homeline 20 Amp Single-Pole CAFCI Circuit Breaker is rated 4.8 out of 5 by 4.
Rated 5 out of 5 by from worked just like it said... worked just like it said
Date published: 2017-07-18
Rated 5 out of 5 by from only new construction wiring !!! only new construction wiring needs to be arcfault protected in the bedrooms ( all electrical openings outlet, switch, light box, smoke detector ) and soon to be all rooms either AFCI or GFCI,not existing wiring. if you still want that you need to find and seperate shared Wht Neutral wires and bring a new wht to the Y location

Rated 4 out of 5 by from Now Required in Kitchens Code changes have expanded this to be required in other areas besides the bedroom, in existing construction. Ask your electrician. If installed, and tripping occurs, then arcs, or a ground touching a neutral wire, will be the issue. Exploratory circuit division (at a mid point, etc.) is required to track down the fault.

Rated 5 out of 5 by from Arc Fault Breaker After a pal helped me install a new load center, I saw in the NEC that bedrooms needed AF breakers. I bought three - opened one. The guy we bought the house from was an electrical hack . . . the quality of his work was awful the breaker wd not work in a bedroom. To be able to use them, I'd have to re-wire three bedrooms and I can't afford it. Though I did not use it, I installed it (as a trial) on work I had done in my basement and it worked like a charm. And HD took back the opened unit !!! Make sure to read follow the install instructions - order is important
