Baseboard heaters and Southern Electrical Code

Factual Questions
1

I installed a single baseboard heater in the dining room of a mobile home and had great savings heating with expensive gas and electricity.
I asked an electrician for advice on adding more, and he mentioned that every 220v device must have it’s own circuit breaker. Is that true for baseboard heaters? I can’t daisy chain three of them on the same circuit breaker that would provide enough amperage?

I’m not 100 percent certain, but I thought that the NEC allowed you to hook multiple heaters to the same circuit. You can’t daisy chain them though. You have to hook them in parallel to the same feed. You may have local codes that require each to be on a separate breaker though.

Also, what are you calling “enough amperage”? The NEC considers heaters to be a continuous load so you can’t load the breaker more than 80%.

I misused “Daisy Chain”, parallel of course.
Thanks, I was unaware of 80% for a continuous load. I presume that goes for wire gauge, too.

Yep.

Thanks.
My BS is in Electronic Engineering Technology, my Master’s is Instrumentation and Electronics; they didn’t teach me squat about power or wiring. :slight_smile:
