    Safe/prudent to replace AFCI breakers with CAFCI breakers?

    I am going to be replacing two AFCI breakers after a lightning strike in a house built in 2003. I will be bringing the breakers with me to ensure I get the same brand and specs, but I’m wondering if it would be safe and prudent to replace them with CAFCI breakers (assuming I have a choice)...

    Lightning strike damaged 2 AFCI breakers. What to check after replacing breakers and testing outlets

    Background Two weeks ago, lightning struck a tree in our yard. Many circuits tripped and several electronic devices failed. There was a strong smell of ozone/electrical burn throughout the house that has since dissipated. Two AFCI breakers are still problematic. Both serve bedrooms (hence AFCI)...

    AFCI keeps tripping - replaced outlet, checked switches - how to choose replacement?

    Our family room is part of an addition built a few years ago. We had an issue with nuisance tripping on an AFCI and the electrician came and replaced it saying the one we had was later found to be faulty. All was fine until I bought a new Denon receiver to replace an older Onkyo. I plugged the...

    AFCI nuisance tripping?

    An electrician I talked to said that AFCI breakers on old (1950s) wiring tend to experience a lot of nuisance tripping. I plan to install several GFCI receptacles. If I use AFCI/GFCI receptacles, are they likely to have the same problem?

    Replacing a standard slimline GE breaker with AFCI on a mulit-wire circuit

    Hi all! I am new to this forum. I will be updating an electrical 20 amp circuit from a home built in the early 80s. Since I am modifying a circuit, the NEC requires that I update the existing circuit breaker with an AFCI. As you know, the AFCI is twice as wide as the existing slim line GE...

    GFCI issue that is not related to the circuit it's protecting.

    Having lost my father in law many years ago, an electrician and electrical engineer, I'm now at a loss for a sounding board for any issue that comes up that I get stumped with. I am hoping the fine folks here may be of some assistance. I am having a GFCI/ AFCI issue in my sub panel...

    Am I stupid to replace a AFCI breaker with a regular breaker

    Long story short: I had a electrical problem on a circuit that powers our backyard lights and outlets a few months ago that fried the circuit breaker too. Electrical problem was fixed and I had an electrician swap out the breaker for a new one. At the time, he offered to replace it with an...

    CAFCI/GFCI Gremlin on sub panel

    Ok, I've got an issue I can't figure out to save my life. Background: I'm putting in a 100a sub panel in my detached 2 car high bay garage. Other than a 50a and a 30a 240v circuit(s), everything is on 20a circuits with CAFCI/GFCI Plug on Neutral Homeline circuit breakers...

    AFCI or AFCI/GFCI breakers?

    Selling our house to move out of state. Been working for quite a while to purge/pack/fix many small issues (mostly cosmetic), and paint. I have had to fix several electrical issues left me by previous owner who happens to be a licensed electrician. I had the electrical service upgraded in 2003...

    AFCI breaker tripping ONLY WHEN grid tie solar system active

    I had solar installed professionally 3 years ago. The home is 10 years old and has 3 AFCI breakers for bedrooms. One AFCI circuit was hardly used. A new mini fridge was plugged into the rarely used circuit. The mini fridge (60 watt) now causes the AFCI breaker to intermittently trip. I moved...

    Availability of AFCI breakers for Cutler-Hammer BR Loadcenter subpanel?

    I have an old house, built 1925 that still has part of the wiring in the original separated 2-conductor on post style of wiring to 2 rooms, all off of one 15 A breaker. I was originally hoping to put in grounded plugs without necessarily rewiring, but that doesn't look legal. I'm wondering if an...

    Why is my AFCI breaker tripping?

    Hi. Recently, one of my AFC I breakers began tripping any time even a small load was put on it. To make a long story short, I have replaced all the receptacles and switches on the circuit and have replaced the AFCI circuit breaker. Really the only 2 things left I haven't touched are two...

    Breaker GFCI AFCI

    Hi Everyone, I have a question regarding GFCI AFCI Breakers in my main panel. I have a Siemens residential household box with QP breakers. I wanted to replace a standard one with a GFCI AFCI Breaker. I noticed that the cable conduit that houses that circuit has a black, red, and white wire...

    AFDDs are a massive fraud

    Derailed another thread with AFDDs, so I am starting this one. I will simply say that UK RCDs and MCBs provide arc fault protection as is. UL not only knows that, but extensively researched UK power systems in an effort to emulate the very same concept 40 years. One the simply fact (growing...
