Hi Guys,
I am wiring an electric furnace. I have never wired one before. It takes 2 - 2 pole breakers. for the L1/L2 I assume minimum amps is 35.6/39.4 for the 60A breaker and a max of 52.1/56.9. It doesn't say min and max, just min ampacity, which I find confusing.
How do these work, does the circuit board change the amperage based on demand? I am assuming the thermostat will determine how many amps to send to the resistive electrical element, like a high medium or low. Low being 35.6/39.4 and high being 52.1/56.9. Is that correct? Also, L3/L4 is that a second stage? So it only comes on when it needs it?
