I know that ENT is not allowed in a direct burial situation, but I've seen it done all around in Washington. I have asked other people in the trade and they say that's it's allowed, but the 2005 NEC says no in 362.12 (5). Does anybody else see it in direct burial. I have travel outside the counrtry alot, and other countries love it. You see it all over the place. I think everything in the Bahamas that is new uses it.
