Conduit Fill

[magicman76]

This is for 2 - #1 AWG and 1 #6 AWG for a 125' run. Thanks in advance guys, I just want to double check the calculation, its been a while.

#1 .1562 Sq. In. x 2 = .3124 Sq. In
#6 .0507Sq. In x 1 = .0507 Sq. In
.3124 + .0507 = .3631 Sq. In

At 40% fill which is required for over 2 wires for schedule 40 and HDPE

1" .333 Sq. In. < .3631 Sq. In
1-1/4" .581 Sq. In. > .3631 Sq. In

So 1-1/4 would be the smallest conduit size that could be used for this application

I just ran your numbers and I agree. The smallest size schedule 40 PVC conduit that you could use for the wires sizes you gave would be a, 1 1/4" conduit.

I did assume you were using THHN, THWN, THWN-2 conductors.

Yes I'm sorry, I'm using THHN, THWN, THWN-2 conductors.
