Arc fault trips under load

I have installed 6 new receptacle on a 20 amp arc fault breaker. When ever i plug a vaccum or multiple lamps in the breaker trips. Everything is new from the wire to the wire nuts. The brand of the panel is square d qo and the breaker is the same. How I have the receptacles wired is on the screws,not spliced in box with pigtail to the receptacle dont know if that makes a diffence.

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

15amp Eaton Arc fault breaker type BRAF trips every day at same time. There are no high amp electrical things plugged in. What is causing this? should I have it replaced?


"Arc fault" breakers trip when an arc occurs, either in a receptacle or a light switch, for example. An arc can be caused by an old light switch, when turning it on. An arc can also occur when you unplug a chord while the device is still turned on or running.

Installing arc fault interrupter with ground fault


If you meant arch fault with ground fault then no, the two types interfere with each other and trip the breaker as one senses an arch and the other grounding.
If you meant ground fault breaker with a GFCI. receptacle, you only need one of the two, either GFCI. breaker or receptacle.

and for circuits, you can put up to 12 devices (i.e receptacle, light)assuming they consume 1 amp each. Anything over 12 amps or 80% of the rating on the breaker, it will trip/reset.
Or if your talking about wires on a breaker then no more than 2 wires recommended. Try adding a junction box outside the panel if your trying to add other branch circuits or tap off of a receptacle.

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.

I have a question


Sounds like the breakers are mis-wired. This is a common mistake with those kind of breakers. The white wire that is permanently attached to the breaker (usually coiled) connects to the neutral bar in the panel. Look closely on the breaker, you will see two terminals. The white (circuit) wire that goes out to load connects ONLY to the neutral terminal _on_ the breaker itself, _not_ to the neutral bar in the panel.

20 amp breaker pops with only a light (60watts) and a small tv on. samething occurs in another room with an iron and a light on, These items can't possibly be brawing 20 amps. Is there a problem with these...


I have been an electrician for 11 years and when these breakers came out in 2005 what a nightmare. These circuit breakers are extremely sensitive. They are designed to sense loose connections and to protect your house from fires caused by them. By increasing the load (ie. more lights or tv) it increases the size of the "arc" created by the loose connection and the circuit breaker trips before the 20 amp maximum. What I normally find as the cause is a loose connection in one of the receptacles or switches on the circuit. A lot of times, installers will use the "quick stab" inserts on the back of the outlets or switches instead of the side screws. Usually, if you "side screw" all of the receptacles and switches it will resolve the nuisance tripping. One other item that can cause them to trip is too many dimmers on the arc circuit but it doesn't sound like that is the problem you're having.

Ground Fault circuit Breaker trips each time a load is applied


The most likely causes in their order of probability are: 1) water somewhere in the circuit causing the hot wire to ground; 2) a legitimate trip caused by a defect in a device plugged into the circuit; and 3) a defective GFCI breaker. In the first case, wait until it has been dry for about a week and see if it trips. In the second case, make sure there is nothing plugged into the circuit and try resetting. In the third case go ahead and put the regular breaker in, then put a GFCI outlet into the first box downstream from the breaker. If installed according to the directions, that outlet should protect all of the outlets downstream.

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.
