Question about Electric Electrical Supplies

1 Answer

The breaker itself does not seem to trip completely. The power will go off to the lights and outlets on the circuit for the breaker. When attempting to reset, the breaker is not in off position, but when you switch to off and back on again power is restored. I just smelled burning plastic and found smoke coming from an outlet on that breaker circuit. The outlet did not have anything plugged into it. I turned breaker off. The outlet is charred, but when i removed the outlet the wires are not melted. This was the only outlet affected.

It is a clear case of metal contacts getting heated/melted/burn out due to overload/short-circuit inside. Please get the circuit breakers replaced with a new one to avoid fire hazard.

Hi Sammy,
It sounds like there is a direct short on the circuit. Before going any further, check other outlets on this circuit and make sure they do not have anything plugged in that is not expected and does not work. Check OUTSIDE your home, basement, garage, etc. as these locations require GFI protection - and may be fed from the bathroom outlet. After removing devices that are plugged into the circuit, attempt a reset of the breaker once more.
It is not likely that the circuit breaker has failed (but is a possibility). The outlet in the bathroom is probably a GFI type. You can determine this if it has "Test" and "Reset" buttons on it. You should be able to press the Reset button in fully even with power off. After resetting, you can attempt the resetting the circuit breaker as you have described above. If it stays on, try pressing the "Test" button on the outlet. Doing so should trip power to the outlet (and causing the "Reset" button to pop out) but leave the circuit breaker "On". If the breaker also trips, the GFI outlet is suspect and might need to be replaced.
At this point, a qualified electrician should be consulted to locate and clear the wiring fault.

Why would two adjacent circuit breakers in a panel trip for no apparent reason? We reset them and everything seems normal.


My first thought is that even though it's only feeding that single outlet in the room; many times the neutral wires are made together in a panel (neutral/ground bar),which tries to carry the load of the initial tripped gfci. and tripping itself. Was there a decent amount of power plugged in to either the 'dedicated' outlet or the series of outlets that go to the 2nd breaker?

Lg microwave oven trips circuit breaker


The magnetron probably has a partial short pulling more current than normal as it runs, the other two items that give trouble is the high voltage diode, "sometimes cracks" to the high voltage capacitor, "usually shorts"

Home fuse box breaker issue


Hi Rex,

It sounds as if the upstairs bathroom outlet and the outdoor outlet are on the same circuit. There's a very good chance that these are GFI or "ground fault interrupter" type outlets, as these locations (and others) have required this type of protection for over 30 years. It was a common practice to run a circuit from the panel to one of these locations (or another) and then run from here to the next outlet and then on to the next. Since the GFI outlet could be purchased for around $10 instead of $30 for a GFI breaker, electricians would install outlets instead - both offered the same protection. A "regular" breaker would supply power to this circuit - but the very first outlet would get a GFI type outlet. It would be wired to the LINE terminals and the cable that feeds the rest of the outlets on this circuit would be connected to the LOAD terminals. If there was a ground fault condition, this GFI outlet would trip, but the circuit breaker would remain on. You would locate and RESET the tripped GFI outlet to restore power. The only time the circuit breaker would trip is if the circuit was overloaded. Overloads would NOT cause the GFI outlet to trip.

Now that you understand how it was typically wired years ago (and still a lot of times today), you should check all the outlets outside your home, in bathrooms, basements, garages, and inside your home next to doorways that lead directly to grade of your lawn or deck. These are required places for GFI protection. Press the RESET on any tripped GFI outlet to restore power. If the outlet will not RESET, there is a condition where the hot wire (black, red or blue insulated wire) is in contact with ground, or a device or appliance connected to the circuit has a problem. Unplug anything connected to the circuit and attempt to RESET again. If still unable to reset, open the outdoor outlet again and carefully pull it out and away from the box. Inspected for damaged or crushed insulation and repair / tape as needed. Before reinstalling, try to reset again. If it holds, trip the GFI by pressing TEST button. The RESET button should pop out. Reinstall the outlet and make sure the wires are not crushed or cut. Press the RESET button again. If it trips, you will have to remove the outlet again and take more precautions against damage to the insulation. it is also possible that the GFI outlet itself has failed, in which case it should be replaced.

GFI circuit breakers and outlets are supposed to be tested monthly by simply pressing the TEST button and then the RESET button. Replace any GFI device that does not test correctly if wiring and devices / appliances connected are OK.

I hope this helps & good luck! Please rate my reply - thanks.

Why do i get power at the 120v outlet but nothing works when its plugged into the outlet


It sounds like a bad neutral wire. Somewhere the neutral is not properly connected. Most residential wiring operates on a 240 single phase system comprised of two seperate 120 volt legs. Connect between either leg to the neutral gives you 120 volts.connect btween the two legs gives you 240 volts. If the neutral is not present the circuit will search out the other leg to try to complete the circuit causing dimming of lights extremely bright lights and all around chaos. Check ahead of the main to see that the voltage is correct. Check each leg to neutral with a voltage tester. Have some one turn some lights on and off while checking as sometimes a load is required to get fluctuating readings. If the reading fluctuate wildly the problem is between the power grid and the panel. If not recheck on a a couple of breakers and if the readings fluctuate it is on your side of the system.
. Hope this helps

Everstar mpm2-10cr-bb6 will not reset on power cord. light on reset doesn't light. seems like no power is getting to the unit.


Check the outlet that the unit is plugged into, to be sure that it is in fact, working. The circuit breaker in your home's circuit breaker panel for that outlet, may have tripped. Also, the outlet may have interior damage or a loose wire connection. If the unit seems not to be getting power, one of the above is the problem. Try plugging the unit into another outlet in a different room.

Hope this helps you troubleshoot and solve the problem.

I have a Bosch b52l iron, when i turn on the steam button, it cuts off the power, what could it be


It could be the iron itself (it may have a short circuit in it) and the circuit breaker trips when the steam switch is turned on.

Option 1)
Another option is that the entire circuit that that circuit breaker is controlling is overloaded. What other outlets / applicances / lights are disabled when that circuit breaker trips? You may have to iron only when those other applicances on that circuit are not being used.

Option 2a) Your outlet may be damaged and causing your circuit breaker to trip when the high current STEAM setting is set.
- OR -
Option 2b) the circuit breaker is damaged and is tripping too easily. Only replace with a similarly sized circuit breaker (15 amp lis likely but is says right on the breaker).

Try the solutions in that order.

All lights up but as soon as i press the start buttom its trips the sockets out


I assume "trips the sockets out" means that the fuse or circuit breaker that supplies the power to the washer opens or moves to the "trip" position. I'll also assume it worked fine while plugged into this outlet before, too.

This indicates a "direct short circuit" or a very low resistance short circuit, and is potentially dangerous to people and property. Do NOT attempt to reset the circuit breaker or replace the fuse to try it again. This appliance requires a professional repairman to locate and repair the problem before you should attempt to use it again.

Be safe & good luck!

Refridge stopped working after a power surge


First, check to see if the light comes on or if there is any fan, motor, or other sound coming from the appliance? If so, the refrigerator isn't really completely stopped--go to the specific problem you are having. If not, try adjusting the thermostat to a colder setting. If that doesn't work, read on.

Second, check to see if there is power getting to the refrigerator. To do that, plug a lamp or other device into the same outlet the refrigerator is plugged into. If there's no power, check the fuses or circuit breakers. If the fuses or breakers aren't the problem, contact a qualified electrician to restore power to the outlet.

If there is power to the appliance but it still seems to be stopped, there may be a problem in one or more of these: 

  • Wiring


  • Thermostat


  • Defrost timer


  • Compressor


  • Overload and/or relay

GE Spacesaver microwave trips the circuit breaker


Since power = voltage X current, 1.58kW / 120VAC = 13.166A

So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.

Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.

Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.

A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.

If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.

If it passes this test, the problem is likely in the microwave.

We're happy to help and we appreciate your thoughtful rating of our answer.
