well it's supposed to protect you from drawing too much off one circuit like say having the toaster and the coffeemaker plugged in with the microwave. In reality you should be ok, to make one thing clear the code is in place FOR safety, that's why it was written. Safety and code go hand in hand. There's not some lawyer sitting somewhere giggling making stuff up lol.
Provided nothing else is botched up to badly you shouldn't burn the place down if it's all on one circuit for the time being till you can get it done right.
if your house burns down it's not my fault
