Air Conditioner Unit?

I have an old house that has two small bedrooms on the same 15 amp circuit. The occupant has two small 5000 btu air conditioners that run all the time in these two bedrooms. Sometimes in the late afternoon the breaker will switch off on this circuit. This happens only in the late afternoon. Any ideas.

Late afternoon, when power consumption in your area may be high, voltage drops slightly, rising the current to trip the breaker.

It's a pretty simple case of overload. If you are willing and able, you can improve the electrical supply by adding circuits and possible increasing the service size. This is going to cost somewhere between $100 and $3000, depending on circumstances. You could get an estimate from an electrician.

If you are unwilling, the occupant will need to stop using one of the units, turn them down, or find another circuit for one of them.

It's a straightforward case of the supply not meeting the demand. You either need to increase the supply or decrease the demand.
