Whenever the radiator is on and the Home theater is on the circuit breaker trips. Help! :mad:

Radiator?

I presume you mean electric heater?

... or when you start your car? :)

Run your HT or "radiator" on different circuits. Should be pretty easy to test.

BTW... you may want to edit your thread title to be a little more descriptive.

Remove the "radiator" from the circuit and put it on its own circuit. Better yet put them both on their own circuit. keep you, your friends and family and your equipment safe!! If you ask me enyone with a HT should pull a dedicated circuit for it. I have seen what happens to overloaded circuits, it's not a good thing!

Yes that is what I mean. The house is a rental and probably wired by monkeys and is very old. :(
