424.3 Branch circuits Allows 15/20/25/30.
Electric heat Thermostates come as high as 22 amps as far as I see. So over 20 Amps Contactor required.
Thermostate rated 125 & of load (unit Switch as disconnect 424.20) =
Off position / two poles Located per 424.19.Within sight of heater OR breaker lock on branch circuit breaker rated 125% of Load.
Another words if a Heater is Not within sight of the ther.
there must be a Fixed breaker lock on breaker feeding that circuit.
Ther. Must be 2 pole , rated 125% of load, Off position,
not over 20 amps without a contactor, within sight of heater unless breaker lock on circuit breaker.
