A new computer is tripping a Siemens AFCI 15 amp breaker as soon as I press the power button. I purchased a UPS to try to eliminate the issue but it's persistent. I swapped out the power supply on the computer but the issue continues. The computer is in a bedroom being used as an office (and there are no plans of it ever being used as a bedroom).

Two questions:

1) Can I simply swap this AFCI breaker with a normal breaker to eliminate the spurious trip?

2) Am I going outside of electrical code with this bedroom-turned-office if I swap to a normal 15 amp breaker?

Thanks.

Popcorn. I have two of f those sons of bitches that trip if I so much even look at the outlets they control in the garage. I can't plug a fricking nightlight into them without throwing the breaker.

Yes.

Yes, but no one will ever know unless you sell the place and have a home inspector that actually touches the panel, thatd be a first.

That being said, it could be a bad breaker. They were notoriously bad when they first came out.

Try to plug your computer in on another circuit that is also an arc fault and see if it trips again if the next one trips it’s more than likely a problem somewhere with your computer

yes they were bad when they first came out but they pretty much have all the issues worked out on the newer ones

I have the same freaking problem. It's connected to my smoke alarm so whenever it trips, the smoke alarm goes off. It just recently went off and I went to turn it back on like I've done on many other occasions and it wouldn't stay on. Therefore, I assume it's bad. I put a call in with the electrician who installed the panel a few years back but I haven't heard back from him.

Is this something that I can replace like a regular breaker? That extra ground wire has me a little spooked.

Have you tried plugging the computer in on other AFCI protected circuits? That would let you know if the arc is happening due to the computer or to something else

current code requires AFCI protection in an office as well if you are in Louisiana

that being said, yeah, you can do this, but I would still troubleshoot further to make sure the arc is due to the computer and not another underlying issue

Just wanted to say thanks for all of the replies. I've been too busy to do anything with it except I can share that the computer also tripped a GFCI circuit. Since I've used a computer of similar power supply and power loading in that spot for years with no issue, I'm fairly certain it is something about the new computer that is causing the issue. I've never had a computer have a short where the computer actually still worked. So, I'm unsure what to think. I'm leaning toward swapping the breaker so I will probably try another AFCI circuit just to confirm it still trips and from that decide what type of breaker to buy.

Thanks again.

Change it out with a regular breaker. That’s what I did when having the same issue. Problem solved

I finally swapped the breaker. There was indeed a panel to neutral bar. Thanks for everyone's help. It no longer trips!
