I have a couple questions regarding installing a subpanel for when I finish my basement. A little background first. I was planning on replacing two of my "thin" breakers with a double-pole "thin" breaker (50A) for the subpanel. First question, what size cable/wire should feed the subpanel? Secondly, is the neutral and ground to be isolated in the subpanel? My final question regards to the location of my subpanel. Is it OK to install the subpanel between my main panel and my dryer duct that runs up the wall and out? Any comments are appreciated. Thanks.

Feed the sub panel with #8 THW or THHN protected at 50 amps.

The neutral and ground must be isolated in the subpanel. You can purchase a ground bar at the same supplier you purchased the subpanel. It is mounted to the holes you find in the panel.

You can locate the sub panel between the main panel and the dryer duct as long as you have 3' X 30" open space from floor to ceiling in front of the sub panel. That is 3' in front of panel and 30" wide. The 30" wide area can include the main panel. Nothing can be in front of the new panel.

Hope this helps
