Has anyone used other than schedule 40 and 80 pvc underground?
I have a contractor who wants to use pvc that is manufactured in 20ft lengths underground I think it is schedule 20 but not sure. He wants to pull direct-burial cable through it.
I can not find pvc other than schedule 40 and 80 listed in the NEC, so I am not permitting him to use the other, because it is not listed.
He feels that because he is using direct-burial cable he really doesn't need to use any conduit at all and any pvc should be acceptable, I feel that if he choses to go beyond the requirement the method still need to be code compliant.
Thank you in advance for any help.
