Hi all,
So I have just started my inspecting career and have already come by lots of interesting things. My question is this:
An underground service is using 4/0 Al. The EC is using 2 #6 Al conductors for the GEC. I am under the impression that a #2 Al or a #4 Cu or cross sectional equivalent is reqd.
2 #6s is 26.6 sq mm and a #2 is 33.63 sq mm. Is my analysis correct or am I missing something? Be gentle I'm new, lol. Thank you all very much.
