Wireway

[patpappas]

Figuring wireway area for 24 750 MCM thwn for a 3000 amp 208V service, switchgear will be 2' from the transformer. I have hit a road block in figuring this out. Help.

What is the insulation on the 750? THHN/THWN? XHHW?

How long will it be? Will there be any joints?

24x 1.0496=25.2

25.2 divided by 20% fill = 126

12x12=144

A 12 by 12 would work but I'd go larger if possible.

Thank you, just went brain dead, no joints to be made up, distance 2'.
