I am trying to figure out if I need to run new wire to my new heat pump. It shows 28amps ampacity with 40 amps min and 45 amps max...
We ran 10/2 to it. the brkr makes a slight humm when it starts. no brkr pop. My question is does the amp draw split in half over the two conductors of 110v each or does it remain the same over both. IE 14 amps versus 28 amps. I know the amount of Watts is halved when you run 220 v versus 110v.
Charts show ampacity for #10 wire at 55, so I believe I am okay???
Thanks!
