I live in an old house; it has old electrical infrastructure. Last night it was really hot, and we were running an external dishwasher on the same circuit as the TV and a fan and a ceiling fan. Only the TV is connected with an extension cord because there just isn't a three prong outlet in that room, but sadly it's still on the same circuit. The TV is an older flat screen from maybe 2003 or so, the dish washer is brand new.
When it was hot last night the breaker kept switching off, and I had to unplug everything from that circuit and reset the breaker.
Is there any way to calculate how much a breaker is likely to be able to handle, so I don't have to keep running up and down the stairs to fix this?
I do have things running in other parts of the house as well, but they aren't on the same circuit. They only blew once or twice; the one in question blew like 4 or 5 times last night.
