nec code on wires in 2'' ridge

[tcsperson]

Can 3 #2, 1 #6, 4 #4, be ran in 30ft of 2'' ridge pipe( burried )? and where in the nec code would help break it down, I've been looking in 310.60 section. I thought that in 2 inch ridge you could run 8 # 2 wires.


Thanks for any help!

Go to chapter 9, use the applicable tables for the particular conductor types and raceway then do the math.

BTW, welcome to the forums.

il take a crack at it...

assuming thwn-2
3# 2awg .1158 x 3 = .3474
1# 6awg .0507 x 1 = .0507
4# 4awg .0824 x 4 = .3296
+____
.7277
plus grounds...

2" rigid excepts a total 1.363

I say party on!

But im a noob so dont go beting the farm on me.
and its 11 2awg thwn-2 in 2" rigid

I am very prepared for some criticism on which steps i might of missed here so let me have it boys...:-?

That's not part of the question.

..............2" rigid excepts a total 1.363...........

2" rigid at 40% fill is 1.363.
