Can I use a nuetral for a subpanel that is one size smaller than the hot conductors?
I am in a sitaution where I am completing a job I did not start. The existing pvc conduit run from the main panel to the location of a subpanel is 1-1/2 inch schedule 40. I need to get the maximum amperage feeding this subpanel from the existing 200A main panel.
I plan on using 2x #1 conductors for the hots, 1x #2 for the nuetral and a #4 for the ground, all copper. And feeding the hots through a 125A 2p circuit breaker.
Does this sound right???? I don't think I can easily get anything larger through the 1-1/2 inch conduit. Any thoughts?
