I just got done running a new 60 amp circuit to a sub panel in new room. new room has 4k in lighting, co2, dehumidifier, a/c and all climate control devices. my question is after running the sub panel, the main lead to the 125A breaker is getting hot on 1 of the hot legs. the main terminal on the breaker seems to be loose, but not loose in terms of set screw not being tight, but maybe an issue with the main connection to the breaker. what is normal in terms of temp on main wire. I dont believe im pulling too much power but unsure of total house draw. cant imagine im in the 125A range. thank for any help.
