3000watts 14/2wire, 240volts, 15amp breaker...???
Seems the 2 750watts heaters I had turned out to be 1000watts each.
Brings my line up to 3000 watts, instead of 2500.
As I understand it, puts me 120 watts over the limit.(according to https://www.icmag.com/modules/Tutori...afety/1655.htm)
Is such an overage a deal breaker...???
Thanks

1000 watts divided by 240 volts equals 4.1 amps no problem for 14/2. A 15 amp circuit should only be loaded to 80% or 12 amps.

The heaters are considered *continious* load , therefore both the conductors and breaker would have to be sized to accomodate 125% rating.
3000W /240 = 12.5 amps X 1.25 = 15.625 amps
which means 12/2 cable throughout the circuit and a 20 amp double pole common trip breaker.

Ok, thanks guys. I'll take one 500 off that line and put it on another line, that have 12 gauge to start with.
I was certain I had bought 12/2.... somehow ended up with 14/2 and didn't notice it until I had completed the first line.
Oh well...
Thanks again.
