Question Two 240V 1500 watts baseboard heaters on one circuit double pole 20a breaker

Currently we have two 240v 1500 watts baseboard heaters on single circuit protected by double pole 20amp circuit breaker.

Is it safe to turn on both the heaters at highest heat at same time without any risk?

You'll be drawing 12.5 amps, so if there is nothing else on the circuit, you will be ok. "Risk", is why the breaker is there.

Baseboard heaters are either off or on. When they are on, they are at highest current draw and when they are off there is no current draw. Turning the thermostat very high does not draw any more current than their normal cycle.

Why breaker is there? what is the risk for having breaker?

I just want to clarify that when I said 20 amp double pole circuit breaker means total 40 amp
so 40 amp is ok when total required is only 12.5 amp? I dont know the size of wire ...

also can you please explain what do you mean when u asked...why breaker is there?

No..... a two pole 20 amp circuit breaker is 20 amps at 240 volts.
Since your heaters are drawing 12.5 amps you can't use any smaller breaker as the code only allows you to put an 80% continuous load on a breaker.


You asked if there were any risk. Chandler replied that risk is the reason we use circuit breakers. That is what it is there for.
