Example: circuit number 1 consists of relay r1 r2 and r3. r1=500W, r2=250W, r3=350W. Total load =1100W. So the conductors (H,N &G) from the source panel to the relay panel will be sized for 1100W? On the other side of the relay panel, the hot wire for r1 is sized off of 500W, r2 for 250W and r3 for 350W? Or should the conductors be sized off of 1100W for everything?
I am sorry if my post is confusing, but any help would be much appreciated.
