I'm running a new 60amp sub panel and have been debating what wire to feed the sub panel with. I have 6/3 NM-B (75 deg) right now, NEC says this is good to 75 amps or so, but i must use the 60 degree rating of
55 amps. If both my double pole breaker and my lugs are rated for 75 degrees can i use this wire or should i just go to a 50 amp Sub.- posted
