Hi, here’s what I’ve got-
Have an air handler for an air conditioning system I am wiring that requires 230V service. At the air handler’s electrical hookup box, there is an L1 and L2 terminal for the hot lead hookups. Then in the same box there is a “ground lug”.
I ran 3 wire w/ground romex to the unit from a subpanel I added near my main breaker box. In my subpanel, I have a single pole double throw breaker. I have one hot lead (red) into one half of that breaker, my other hot lead (black) into the other side of that breaker. My white (neutral) is attached to the neutral strip in the subpanel, my ground wire is attached to a seperate neutral bus strip within that subpanel. My neutrals and grounds do not meet until you get back to the main breaker box from which that subpanel is fed.
1) Should my neutral and ground be connected to the same “ground lug” in the air handler’s control box (manual doesn’t say)?
2) Is my subpanel grounding correct based on my description?
Any info appreciated.
