A breaker listed as 15 amps is tripping after about 1/2 hour after running a portable air conditioner that is listed as 10.5 Amp. I was using an extension cord that is not rated for high amps, could that be the reason for the breaker tripping? The circuit I was using had nothing else on it.
Welcome. My name is XXXXX XXX would be glad to assist. Please understand, that I must ask questions to insure I know the situation.
was this a regular type drop cord you were using?
yes, I am going to buy an extension cord that takes the proper amps but I was curious if that would trip the breaker or is there something wrong with the wiring.
The cord will definitely create a Voltage drop and possibly higher current than normal.Usually window air conditioners are designed to plug straight into the wall at their location. So any cord is going to strain the circuit on the voltage.
Hopefully you can keep it real short and at the least a 14/2 cord or heavier is beteer suited.
At least the 14/2 cord will be equal to the house wiring
