By the way, I don't buy into the '15 and 20 amp circuits are hard to overload' line of reasoning.
A hair dryer and a vacuum cleaner.
A coffee pot and a microwave. (Just because there are two kitchen circuits does not mean the load will always be dived between them.)
A portable heater and a large TV.
I tripped a 15 amp circuit at the house the other day for the first time in a while.
My wife was using a vacuum plugged into a circuit that a TV and 1,500 watt heater I was using was also on. After about 5 minutes it tripped no harm no foul, moved the vacuum to another outlet and I went back to watching TV.
