Underground service

[pbyrd]

I am not an electrician. People just expect me to find information for them. So please excuse my wording. Someone is wanting to install and underground service at a pier. The information they have says to use UF or USE cable. They would like to use TC cable. Can they do this? Does it violate something and what would that be?

Re: Underground service

What is TC cable?

Re: Underground service

Take a look at 336-10 Uses permitted. TC cable can be direct buried or installed in conduit if identified for the use. I would suggest checking with a cable manufacture.

Bennie, that would be "Tray Cable".


pbyrd, Tell these people they will find the answer in article 336.12 2002 NEC.

Re: Underground service

There must be more than TC in the marking.

URD cable can have many types of insulation and voltage.
