I have two bedrooms and i'm going to put 1 heater in each room .they are 6.25 amp and 1500 watts. they will be wired to a single double pole 20amp breaker with # 12 wire. from the breaker to a junction box then to each heater . does this sound correct, will the single no. 12 wire from the breaker to the junction box be big enough to handle the two heaters.

#12 wire is capable of handling two 1500w heaters at 240v.

You need a thermostat within sight of each heater that opens both "hot" wires and has a marked "off" position OR you need to install a breaker lockout at the panel on the circuit breaker feeding these heaters.

not heard of that . infact an apt. building I work in is upgrading the panels , moving the location of panel to be code compliant , installing gfi breakers for kitchen and no lockouts for electric heat. I think if that was code they would do that too.

If the heater doesn't have an internal breaker or off switch that disconnects both legs and some other rules.

Thermostatically controlled switching devices and
combination thermostats and manually controlled switches

I don't use other electricians work as a baseline for what our shop does.

I follow the code book.

Stuff has posted the code rule. Your apartment electricians might need to have that pointed out to them. In my experience when they miss one thing....there are others as well.

What others have done is not always a example to be followed Aceman & Stuff, have given pretty good reasons why.
