Question about Siemens Seimens Arc Fault Breaker

1 Answer

I have bedrooms with arc fault breakers in them. Randomly, the breaker will trip for no apparent reason. Usually only the lights are on in the bedroom, and nothing is plugged in to the outlets. The room that we thought was the problem child had the breaker replaced; still trips randomly. My brother, the electrician, is stumped.

Hi,

If your arc fault breakers are tripping, then there is an arc developing somewhere along the line from the panelboard to the rooms that the breakers cover. If they are breaking in more than one room, then the fault lies in the lines somewhere between the panel and junction to these rooms.
You would have to trace the line from the panel to each light/outlet until you find the problem. Remember the arcing could be occurring anywhere, in the line, at the light, or at the outlet.
Your brother should be able to check each section of wire for continuity rather than ripping out all the wires in those circuits.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

Handie Andie

Why are these breakers hot and constantly draw .35 amps from the ground bar?


When current is going through wiring and devices it normally operates warm. That is why most wire and devices such as breakers are rated at 70 degrees Celsius. In a panel, heat can be transferred through the buss bar they are connected to.
Breakers will trip for 2 reasons. Overload amperage and heat.

I have 3 bedrooms, each have their own arcfault breakers. i plug in a sawzall and one bedroom trips, fast at the end of the circut an takes longer at the begining. i have chect for shorts, removed and...


Hello. The issue could be with the saw itself. If the breakers are 15A (and for bedrooms, they should be) and the tool draws that or better, then the breaker will trip. The reason it trips faster at the EOL (end of line) is due to the resistance in the wiring itself. The further away from the initial source - the more loss/resistance.

Truthfully, the arcfault function is designed to detect arcing in a circuit. AFCIs disable the circuit immediately if they detect any type of problem (read "arcing") in the circuit. since the sawsall motor functions DUE to acring of the brushes on the motor, your circut is actually behaving according to design.

The final issue could be that the tool IS causing an issue, and may need repair.

Hope this helps.

Do you have anything plugged in? If they keep tripping with nothing plugged in I would call a electrician to troubleshoot or replace the breakers. They may still be under warranty from Siemans.

Arc fault breaker in Bedroom,trips when I plug in my computer laser printer,the printer works ok in any other outlet in the house except the master bedroom that is protected by a arc fault breaker.


My experience with these breakers is that there could be some minor short in the equipment that cause them to disconnect. I have a filter motor that will not run on my ground fault breaker if it gets wet. There may be no problem with the breaker.

Eaton Arc Fault Breaker type BRAF tripped. I reset it but lights will not work. Ideas please?


My arc fault breaker trips in my bedroom when ever a load is put on line. The trunk line comes into a three gang switch box and feeds the entire room. At times I can turn my ceiling fan and light on for 10 to 20 minutes before the breaker trips. Other times the breaker will trip when either switch is first turned on. I plugged a 4 watt night light in a wall receptical, without the ceiling light or fan on, it also trips the breaker. I have had other plug in lamps, 60 watt, work in other recepticals for a while. The problem seems to appear in all recepticals and lighting in the room.

Arc fault breaker trips sporadically


Are there any heaters anywhere in the circuit for this breaker? (ie: bathroom fan w/light and heater) If yes, I would suspect and inspect them first. Also,any type breaker will trip more easily if the electrical connection screws on the breaker are not tight enough...check to make sure that's not the case.

Arc fault trips under load


Arc fault breakers are definitely a pain. First make sure the receptacles are made for a 20 amp circuit. Second vacuums, Curlers,and most appliances will trip your breaker since they create an arc or a short if you will to operate. That is exactly what these breakers are made for. To stop the arc. Apparently they never really thought the whole arc fault thing through. As per code in most of arizona you only need this breaker in bedrooms where this type of appliance is not used. They also are more prone to popping so make sure you aren't running something on each of the receptacles at the same time

3 combination arc fault breakers tripping under load


What is happening is the white wire that comes off the breaker is probably too close to another neutral or too close to a hot wire that is on one of the other circuits that will make it trip when you use a drill etc... Check to see if the coiled up white wire off of the breaker is not near a hot in the panel. I have had lots of arc fault breakers trip for that reason.
