Here's the scenario: I ordered 4 cuts of 1/0 thhn compact aluminum and 1 cut #2 same for ground per specs on my prints. Run is 420' long 2" emt.
It is feeding a 100 amp mlo 208/120 3 phase with neutral panel from switch gear.
Boss sends out 1 cut 2/0 thhn al, 2 cuts 2/0 xhhw al, and 1 cut 1/0 xhhw al.
Question I have is I believe this to be a violation but have no book here to look it up I am sure you can't mix insulations like that correct?
Would you make the 1/0 your neutral as I think that's a violation as well correct?
Boss says pull it so pull it but how would you mark them?
