Thanks for your answer, but I still want to connect my heaters in series. I revised the circuit like this; Connecting 2, 500W/120V type baseboard heaters ( 28 Ohm each) in SERIES Circuit Feeding it from 240 V, I will get 1000W total Power, but the Current will only be 4.2 Amp, safe for 14/2 wiring, is it allowed by the code?
