How do I reset a Eaton breaker with a tester on it?

If you have a Bryant load center, you can use other breakers in it, including the Eaton GFCB120 GFI since several companies unified their design. The GFI (ground fault interrupter) or GFCI (ground fault circuit interrupter), same thing, may be required for a device you are installing, such as bathroom, kitchen or outdoor fixtures.
The Eaton series includes very clear installation instructions, but if your problem is that they are missing, then all you do is install the breaker in a open slot in the breaker panel, but you have to attach the neutral [white] wire differently. On regular breakers, the neutral goes right to the ground lug in the panel. With a GFI breaker, it goes through the breaker, and then is connected to the ground lug.

you say you have a square d panel and you have a eaton breaker this may be the problem square d should always have a square d breaker and eaton with eaton they dont fit wright in the panel they are made for each other ,you should check the panel and breaker to see if all the wires are tight if there is no problem there check the plug in the wall if there all tight ,it may be drawing to many amps and blowiing the breaker,

I recommend that you call Eaton (the manufacturer) service line: 800.356.5737. Here is the product page for the 3105: http://powerquality.eaton.com/Products-services/Backup-Power-UPS/3105.aspx?cx=3 You can also send an email:[email protected]

The new Eaton Cutler Hammer UL series circuit breakers are made to be interchangeable with panelboards from different manufacturers. If it is a UL series, the answer is yes.

If you disconnect the load wires on the breaker and it will not reset, the breaker has a fatal flaw.

IF the breaker ONLY fails to reset with the load wires connected EITHER there is a wrong connection like servicing a shared neutral 3 wire cable from the breaker, or there is an electrical fault OR there is interference from a source that couples radio-like noise onto the wires to this.

Check mains supply it may be low coursing Cuicit brown outs

If the lever is in the middle position, you will need to move it all the way to the off position, (towards the outside of the panel) and then back to the on position (towards the middle of the panel) If it trips again, try to turn all of the light switches of that circuit to the "off" position and try again. the arc fault breakers are designed to sense loose connections in outlets, light switches and lights. by turning the light switches off it will give you a chance to find out which sets of lights may be causing the problem. keep in mind that it could be a total accumulation of the lights (total amp draw) so if it resets and then trips, try turning on the lights in a different order.

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.

you must push it kind of hard to get it to reset. first kill the 100 anp or 200 amp breaker. that is what most of sizes used now days. it will be the big wide breaker. now pull the wire our of your eaton breaker. if it has 2 wires pull them both. it has just one pull it. move it back where you wont touch it or it wont touch anything else. now reset it again. it it resets you have a bad short down the line. let me know and i will help you run it down. good luck and good day. sawdust46
