I'm fixing to do a panel swap (will be permitted and inspected to 2005 NEC with 2008 provisions, i.e. AFCI) from an old Federal Pacific fuse panel to a Square D breaker box. House is currently BX and some MC from new installs. NM is not allowed per city ordinance.
The reason for the swap is the previous homeowner's handywork and simple age. The panel is a mess and the disconnect for the AC is wired directly to the service entrance lugs. I'd like to do the new run to the AC condenser with THWN in schedule 80 PVC. However, I've also seen XHHN mentioned for use. Is one more appropriate than the other?
