I need to figure this out. I have two 15 amp space heaters in my garage and when i turn them both on it throws the breaker. The breaker at box for this is rated at 20amps. I have been told that i can run both on high and won't throw the breaker. I also replaced the old breaker with a new one (same brand and amps). Could you please help me with this.

thank you

Are they both on the same circuit?

30A is supposed to trip a 20A breaker.

2heater

yes they are and how do if go about to solve this problem?

omzig

Someone told you that you could use two 15A heaters on a 20A circuit?

So are these heaters cord and plug connected? 120V or 240V?

2heater

they are 120v

What is the wattage of each? Should be on the label on the unit?

Why do you need to run 2 15 amp space heaters in one garage? You will not be able to operate them both off the same circuit you will need to find or add a second circuit. This could be easy if the panel is in the garage, TK can help you at length, but are you sure you need to?

two 15 amp. heater units = 30 amps , on a 20amp breaker will cause problems you need to run the units on seperate dedicated curcuits , good luck

As ceiling fan repair brought up, how much heat do you need? Maybe some caulking and insulation would be a better investment. A much better DIY project than running new circuits.

the reason for having both heater's in my garage is to keep the room warm so my family can use it as a play room. both heaters are on the same ciricut. can you tell me how to put in another circuit.
