Most likely becase you might have been coping the grounded ckt. You need the ungrounged ckt. Boats and ships work on Non-grounded systems, the hual is the ground. Hope that might clarify. seth

My 3 arc fault breakers run hot and draw about a third of an amp from the ground bar wire each, 24/7. Is this possibly normal?

How did check amps. I would check the amps on the circuit itself. Might be drawing close to max. thats why it's hotter. breaker should have no more than 80%. Of an amp draw on the circuit

On a 60 FT. run using 12/2/G wire can I use a 25amp. breaker safely?

The size of the breaker that you are going to use on a circuit is predicated on the current draw of the appliance(s) you have on the circuit. Assume you have them all turned on, add up their respective amperages and , voila, you have a close approximation of the size of the breaker. If you do not know the amperage look for watts info. Divide the latter by voltage of 115 and you will arrive at the amps used.

My motorguide trolling motor keeps tripping the 50 amp in line breaker every time I turn it on high speed. It is a 75 lb thrust digital tour model. When I take it out of the water and run it on high...

All motors will draw higher amperage with varying loads. Your hi speed motor winding has probably shorted some its winding's without having gone to ground. It probably needs to be replaced to get your hi speed back. I have run into similar problems in heavy commercial hydronic pumps. Best to have mechanic check it out. An OHM test with factory specs. will tell for sure.

Trips circuit breaker

Copy following link:

Add a comment March 2013 and describe what device is tripping breaker.
Breakers trip when they sense overheating.
This can be caused by too large amp draw, undersized breaker, bad breaker, bad wiring, damaged wires, loose wires, wires are too long, electrical device that is shorted or draws too many amps for the breaker and wire rating.

Not Eaton but Square D. Arc Fault trips with new vacuums Kenmore 21714. Replaced vacuum cleaner, still happens. Suspect design flaw

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 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.

We have two circuit breakers, a 70amp double pole and a 50amp double pole. The 70 amp double pole seems to be fused onto the silver bar and unremovable. The 50 amp is removable. The 70 died out on us. ...

You probably should not replace a 50 and 75 with a 125. The problem is that although the 125 would have the capacity to supply the same current as the combined 50 and 75, each branch would be provided up to 125 alone, instead of the 50 or 70 that they were allowed before. That is, the 125 won't trip unless both branches exceeded their 50 and 70 amp limits simultaneously. If at any time one branch is drawing very little current, then the other branch would be delivered up to 125 amps. If it is OK that each branch can receive 125 amps alone, then a single 125 would be OK.
And if you have damage to the bus bar, you will have to replace the whole box.
On the other hand, if the existing wires will reach, you might be better off simply replacing all three boxes with one panel.
good luck, be safe Al K

How do I run from a 100 amp main panel to a 60 amp subpanel, 125 from my house to the garage

See 60 Amp sub-panel image

Above image shows drawing of 60Amp sub-panel located next to main panel. Drawing shows #6 wire... 125' distance to garage calls for #4 wire. I ran #4 to my barn and have no problems.

Give thought to how many new breakers you want at garage.
See photo of subpanel that holds three 240V breakers

Using drawing as a guide. Replace existing 240Volt breaker with new 60 Amp breaker. Two hot wires connect to new 60 Amp breaker. Neutral connects to neutral busbar.

More space: You can free up space in main breaker box using a tandem breaker. Or by doubling up 2 lightly used 120V circuits onto one breaker. Do not double-up on 240 Breakers

Conduit: You want PVC conduit large enough to fit three #4 wires. Bigger conduit is easier to pull wires ... and maybe later ethernet wire, or alarm wire etc.

Ground wire: You can put a ground rod at garage and run #6 bare copper between sub-panel neutral-busbar and ground rod. Attach ground wire firmly with grounding clamp.

I want you to check with local electrical supply for exact code in your area concerning conduit requirements, grounding, and wire size. Tighten all lugs very tight against wire.

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

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.
