Diagran for 4 wire 240 V circuit at load-side panel ("sub panel").
Does anyone have a link to a diagram illustrating the correct connection of a 4 wire 240V circuit at a load-side panel (showing the correct landing points for neutral and ground)?
Thanks in advance.

Re: Diagran for 4 wire 240 V circuit at load-side panel ("sub panel").
Cannot help w/ a diagram example, but maybe w/ the "correct landing points". On the receptacle those points are identified. At a minimum the ground will be identified w/ a "G" or the symbol for ground which looks like an infilled arrow head, usually pointing down. The "Hots" will be the two identical in shape and size and they are interchangeable, ( black / left, blue / right or visa versa & sometimes red is used. ). In the panel the "Hots" go on the two terminations of the two pole C/B. The neutral on the neutral bar and ground on the ground bar. Hope that helps. I was tipped to an electrical illustrations program by someone on this site created by Mike Holt.

Thanks,
Shows the isolated neutral and ground, which is what I needed!
