2 Heaters Install

[FMC1959]

I have a large room where I need to install 2 heaters (I already have them), each is 240 volt, 8.3 amp, 2000 watt. Is it OK to wire both heaters onto one circuit (2 pole 20 amp breaker, 12 gauge wire)? Or is it better to wire each to its own circuit (each with their own 15 amp 2 pole breaker and for 8.3 amp, 14 gauge wire)?

Thanks

separately your a little over on amperage

Are you actually in Canada or NY? If in the states, you aren't supposed to go over 80% (16 amps) for a continuous load, which a heater is. That being said, I wouldn't hesitate to put both heaters on a circuit in my own house. The rules may be different on the Canadian side though.

So if I used a 2 pole, 25 or 30 amp breaker, along with 30 amp wire (10 gauge), I could have both heaters on the same circuit, without any issue?

BTW - I am in Canada, I have a place in NY I was going to once or twice a month, but not since COVID.

If a heater iis thermostatically controlled, that is it shuts off when it reaches the temperature setting and restarts as the room cools, is that intermittent operation a constant load?

NEC 424.3(B) states that fixed electric space heating equipment shall be considered a continuous load. I wouldn't have any second thoughts about putting 16.6 amps worth of heaters on a 20 amp circuit though. If I have a place where an electric heater(s) run for more than three hours at a time, I am going to be looking into something else real quick.

I suppose you could, I wouldn't just because #10 is a pain to work with. Another thing to consider is the t-stat. Does each heater have it's own, or is there one stat controlling both heaters. If one stat, make sure it can handle the load of both heaters.

I have gone through the pain of working with #10 many times, I can deal with it. Each heater had their own thermostat....so I should be good to go?

I ask because it would save me time, a breaker, and wire to run the 2 on the same circuit vs each heater on their own circuit. I just want to make sure there is no issue.

Thanks

I guess you've never worked with 750KCM.
It's all relative. #10 stranded is quite easy.

It's more than likely romex. (NM-B if you want to get technical). That would be #10 solid. Unless of course there is stranded romex? The box at the first heater would probably have a 10/2 in and out. Plus all the dicking around up and down through the holes and maybe fishing. And you guessed right. I have never touched 750 that I can remember. Done lots of jobs with 500 though.

NM-b does not come stranded
