Question about Electrical Supplies

1 Answer

I have a circuit breaker socket in my kitchen. Connected to it are two coffee pots and a Microwave. Periodically it trips for no apparent reason. Usually when there is only one appliance operating. Sometimes it trips when no appliance is in use. Could this breaker socket be the problem?

First make sure the connections to the fuse box and to the outlet where you have the appliances connected are clean and tight. If they are, next you you might want to replace the circuit breaker with a new one with the same Amp rating. You also have to see which other thing are sharing the same circuit. To do this turn off the breakers one by one if you don't have them labeled, and see which rooms or which other appliances or units stop working which are also turned off once you turn off the breaker that has been shutting down. If there are other things connected to outlets which are sharing the same breaker, not only in the kitchen, but in some other outlet in the kitchen or even some other room, then it could be that some other appliance or heavy equipment might also be draining too much power from a single breaker. Check and see how many other things are turned off somewhere else when you turn off that particular fuse which is shutting down. Hope just replacing the fuse will take care of your problem. If what I have suggested does not do it, then just call an electrician to check it out. Be careful! Hope this helps. God Bless.

I need to know what is the first thing to look at when a mircowave trips a circuit breaker


First off you probably have too many appliances running off the same circuit as your microwave. Try using a different socket. This has happened to me many times at various houses I've lived. For example... My wife uses the hairdryer when I'm warming up some coffee...trips breaker. It basically breaks down to how many circuits your breaker box holds and how powerful it is. Imo Hope this

I have a problem with my whirlpool microwave oven, all of a sudden it shut off the kitchen electricity and tripped the circuit breaker of the kitchen, I unplug the oven and reset the circuit breaker, but...


Hi heshamyg, I want to help you with your problem, but I need more information from you.
Since I could not find the electrical specs for your particular model in the user's guide, please locate the information tag (plate or decal) and tell me what the wattage and amperage ratings are.
Page 5 of your user's manual recommends that your microwave should be used on a 15 or 20 amp circuit And that a "separate circuit servicing only this appliance be provided."
I don't know if this appliance is a new install to your kitchen appliance array, or if this unit has been around and in use for awhile without any problems.
Either way, the electrical circuit is being overloaded; short circuited; or because of a ground fault.

An overloaded circuit is one primary reason for a breaker to trip. It occurs when a circuit has more connected electrical load than it is supposed to have. When more current runs through the circuit than the circuit was intended to take, the circuit breaker is designed to "break the circuit." It does so to prevent overheating of the wire in the circuit, which can cause a fire.

  • The most probable reason the breaker tripped is that you simply have too much plugged into one outlet or multiple outlets connected to one circuit.
  • Move lamps, heaters, irons, hair dryers and other heavy power consuming devices to a different circuit not being heavily used; or
  • Turn off some of the devices on the circuit to reduce the load.
  • Loose connections are another possible but less common cause. With power off, check outlets for a loose wire and the electrical service panel hot wire connected to the circuit breaker to see if it has become loose. Re-tighten the connections if necessary.
  • If these suggestions do not solve the problem you may have a more serious problem such as a Short Circuit or Ground Fault
The Short Circuit is a more serious reason for a breaker to trip. A short is caused when the hot wire (black) touches another hot wire or touches a neutral wire (white). It can also be caused if there is a break in a wire in the circuit. Shorts are a bit more difficult to diagnose because they can be caused by the wiring in your home or in something you have plugged into an outlet.

  • Confirm that the power is off at the outlet into which your device is plugged.
  • Inspect your power cords for damage or a melted appearance.
  • Check your outlets and plugs for the smell of burning- or look to see if there is any visible brown or black discoloration.
  • Check the insulation on the wires to make sure that they are not cracked; and that bare (uninsulated) black and white wires aren't touching together.
  • If you do not find the problem, repeat the process for all the outlets in the circuit.
  • Check for a Ground Fault condition.
A Ground Fault Condition is defined as: An unintentional, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metallic enclosures, metallic raceways, metallic equipment or earth.
In simpler terms, a ground fault condition exists when the hot wire (black) touches the ground wire (bare copper) or the side of a metal outlet box (because the metal box is connected to the ground wire). The ground fault is a type of short circuit.

The fix is the same as a short circuit except check that the hot wire (black ) is not touching the side of the metal outlet box or the ground wire.

If the problem is internal to the microwave oven, have it serviced by a properly trained service technician since one could expose themselves to dangerous levels of microwave energy.

Please keep me posted. Thank-you.

Stelrad ideal mexico super cf100 - electrical problem


There are a couple of things that can be causing your problem. 1. The controller is bad which is tripping the breaker. 2. The breaker needs to be checked or replaced. 3. circuit overload by to many appliances. In any event you will need qualified technicians to do repair. My guess is to start with the controller and have it checked because of its age. After this is done get an electrician if necessary. The kitchen circuit may be a separate issue or part of the problem. If your kitchen or an appliance in it like a stove, fridge or microwave is on the same circuit this will cause a possible overload and trip the breaker. If your kitchen is on a separate circuit and you added another appliance this could cause an overload if in use at the same time.

Over range microwave model jvm1650wb008 fan works nothing else does


Check to see if circuit breaker is tripped in the electrical panel, or if it is connected to a ground fault outlet, it may have tripped. Sometimes there is one ground fault outlet serving others in series in the kitchen.

The gfi trips every time I turn it on


Chances are while you have a 20amp circuit in your kitchen the gfi you are plugging into is rated at 15amps. First make sure your outlet is connected to a 20amp circuit breaker and then change out the gfi for a 20amp one. This coffee pot is more for commercial than residential usage, I had the same problem until I changed out the gfi plug.

Have MCO160UB just quit working


Sounds like you overloaded the amps allowable on your circuit breaker. It can only cope with a reasonable amount on at once, and I suggest that the dryer may have pushed it over the limit.
Don't run everything at once. If the microwave works without everything else on it's fine. You may want to talk to an electrician to see if you can do anything to your circuit box to avoid the problem in future.

My microwave oven keeps tripping the circuit breaker.i replaced the outlet that it plugs into but it still trips it. is there an internal fuse in the oven that may be bad?


If a fuse inside had blown, that would definitely reduce the current flow rather than trip the breaker.
I have replaced several breakers over the years; they no longer last forever.
Try your Amana on a different circuit, not in the kitchen; if that other circuit likes the oven, the breaker is bad. If the alternate circuit breaker also trips, then you have not a blown fuse in the Amana but rather a shorted component inside and repairing the oven will likely cost about the same as replacing it.

Keurig coffee maker causes kitchen electricity to short out.


I'm not completely certain what the problem is because it's not displaying your whole subject (it get's cut off after electricity to...). However, if it is solving the problem by moving it out of the kitchen, it's likely that the problem that the circuit is overloaded. Coffee makers have a large current draw, as do many other kitchen appliances. If you plug too many of them into the same circiut and then turn them on, you will put too high a drain on the circuit and it will cause the the current to become unreliable and then, eventually, through the braker or blow the fuse to protect the wiring in the wall (to keep it from catching fire). If this is the case, you need an electrician to run another circuit or remove some appliances from your kitchen.
