main lug subpanel
I was working on a 200 amp panel and I came across a sub-panel 8 space 8 circuit maxed out that has an overcurrent protection 2 pole 30 amp with a 10/3wire
the 200 amp is maxed out.
Q: wherein the code# NFPA 70# dose it mentions the minimum conductor size for sub-panel?#
P.S i checked in article 408
