I am reading up on my future project and here is a question on wires. This is what I can understand from resources I found:
Air handler - 240V, double breaker - provides power to the blower and circuit boards (2+1 romex, based on the current, #10 should be enough)
Emergency heat strip - 240V, double breaker - separate wire and breaker - provides power to the heating element (2+1 romex, sized by the heating element, #6 for 10KW)
Heat pump - 240 V, double breaker - provides power to the whole heat pump (2+1 romex #8)
The signal wiring (18gauge, 6 or more strand wire) goes from heat pump to air handler and from air handler to the thermostat.
Do I understand it correctly? Or is there a need for a 0 wire for the air handler? I have the space on my panel, but technically I could have a subpanel next to the air handler and distribute the power from there.
