Question DetailsAsked on 8/19/2017

My microwave, coffee maker and stove are on the same circut and it keeps tripping. This has never happened before.

Do you have the same question? Follow this Question

OK - using those high-demand appliances at the same time on the same circuit (even 2 of them) is a mistake. And don't forget the reefer and toaster - normally reefer is a fairly low power demand EXCEPT during compressor startup, toaster (and waffle iron, hot pot,portable electric griddle, george foreman grill, etc) is high whenever in use.

Unless you mean like a toaster oven or such, or a gas stove just using power for controls and lighting, any normal electric range is supposed to be on its own circuit. I suspect you mean a gas stove for that reason.

You would have to check which outlets are on which circuits, but generally in about 70's or newer homes the longest wall of the kitchen outlets are on one circuit, the rest of the kitchen geenrally on another (sometimes a third one for an island with power) - and separate circuits for laundry if in the kitchen, for lighting, and for the stove.

Problem could be one of several things - if you are not able to get one or more of these demands onto another circuit, you would have to get an electrician (Electrical is the Search the List category to find a tech to diagnose and repair this) to come and check the energy demand from each device, the capacity of the circuit, and the demand when the breaker is tripping. Tripping a breaker (or GFCI if that is what is going) is not a good thing - they are not made to be repeatedly tripped and reset, not to mention repeatedly overloading the circuit (which is generally what is happening if it is tripping out) could mean progressive wiring or fixture damage.

Possible causes that come to mind,- you may find you can think of one device/appliance which was just put into use when the circuit tripped out, allowing you to narrow down the culprit.

1) one of the devices is drawing more energy than it should - due to an imminent failure, wiring going bad (so overheating and pulling more amperage), or whatever

2) reefer is tripping it out when the compressor kicks on because the starting capacitor and/or run capacitor (may have one or both) is going bad, so the comporessor is starting hard and pulling higher starting amperage for enough time to overload the breaker

3) you have a wiring flaw in outlet or circuit wiring that is not making good contact, so it is either heating up and pulling power in doing so, or there is a bad outlet with internal wiring issues

4) an outlet is worn from many plugging ins and outs, causing poor contact of the prongs so it is overheating, pulling more juice in addition to the appliance connected to it

5) you have an appliance with a ground fault so it is tripping out the GFCI (if the breaker is a GFCI breaker or you have a GFCI outlet on the wall circuit).

6) you replaced one of the appliances recently and the replacement pulls more power than the old one did

Call an electrician to determine which of the conditions, listed by LCD, is causing your concern. Not an endeavour to be pursued by someone who doesn't understand Volts, Amps, Watts and Ohms
