Rewire with heavier wire and put in larger circuit breaker after replacing current wires.

The breakers are too small to carry the electrical load. It’s possible the wiring and the breakers will have to be replaced. My A/C runs on two 20 amp breakers.

I don’t know what an electrician will do, but STOP turning the breaker back on so the A/C will work or you could have a fire because the A/C isn’t compatible with your wiring!!!

Might need to get the house wired for 220, depending on the load.

I’ve thought about this question since its appearance. And before the electrician, I was wondering if it is you who is saddled with the expense of the appliance, its intallation, and the modifications to your circuitry. It surprises me at this point in your life you don’t know this but; you should NEVER buy an electrical appliance and particularly a major appliance without first knowing the capacity of whichever line of power you intend to plug it in. This The total amps the line can handle is easily found in your breaker box. The capacity for each circuit is stamped into each switch for the line involved. And there is probably writing next to the switch indicating which household sockets the particular switch and circuit serve. If you have a landlord willing to foot the considerable expense involved in the necessary changes, well and good. But if it comes down to you, you might want to assure yourself as to whetheror not you can return the air conditioner for a refund as well as the length of time allowed for you to achieve it. Whoever installed your air conditioner failed you in not telling you these things prior to hooking the thing up.

May not be the wiring, this could be an issue with the unit itself. I’d call back whoever installed it.if there is anything else on that circuit it would be best to remove it.

@Blackwater_Park Landlord is on it.

@RedDeerGuy1 Let us know what was done to fix the problem.

Since you asked, the electrician would first check the rating of the appliance against the rating of the circuit. If the ratings are compatible, they would then troubleshoot, first the appliance, then the circuit, for defects. A defective appliance might require repair or replacement. A defective circuit may require upgrading, up to possibly rewiring the circuit.

Is it a window AC? How many BTUs?

@HP
He didn’t purchase it; the apartment complex bought these for each tenant, so it’s their responsibility.
The building is old and so is the wiringand i am surprised that the inspector of that building didn’t make them upgrade it to the newest standards.

Well, the AC’s load is over the amp rating of the circuit breaker, It’s time to replace them with the amp rating according to the AC unit. You should call an electrician to do this for you. The amp rating of the AC should be written somewhere on the it.

@SnipSnip It is a portable AC unit with exhaust to the window.

@SnipSnip Sorry the intake is to the window.

@RedDeerGuy1 Any chance your apartment is on the same circuit of another apartment??? Maybe your circuit blows when their A/C comes on at the same time as yours. At one point, I couldn’t run my A/C & microwave at the same time. An electrician friend came over & ran a separate line for the microwave & that solved the problem. I’m far from an expert on this subject, but trying to use some common sense. In my experience, my breaker blew immediately upon the microwave coming on…NOT 5–10 minutes. That’s why I think you & another apartment might be sharing a circuit.

Portable units plug into a standard outlet. Either something to else is on that circuit, the breaker is faulty or there is a poor connection in the wiring. This could also be because the breaker is brand new and up to code. AFCI breakers are sensitive to things like vacuums, AC units and microwaves.

Update maintenance worker put AC on an extension cord to a dedicated line that was once for the washer/dryer. Is working fine.

GLAD you now have A/C…just in time for the HOT weather!!! :)

Is your A/C still working for you???

@LadyMarissa Yes.

Update All is well. AC is working fine. They just put an extension cord to the unused dedicated Laundry washer outlet.
