I just wanted to check real quick on the rule on regular 3 wire romex being feed from the house to a storage shed in back yard. not outdoor wire either, pretty wrong in my book but wanted to know the rule on the certain kind of wire. Thanks

Regular NM or NM-B is not for use in wet or damp areas. You can find both the acceptable and prohibited uses in Article 334 of the NEC.

Eric,

Apart from the very obvious issue that NM/NMB is not to be used underground, there can be further problems if this is a three wire feeder from a panelboard to another panelboard, they a 4 wire cable is required.

Also, the depth of the cable trench can be an issue. Not to mention, if they are bringing power to the 2nd. building, then they must put a light outside near the entry way into the building.

Hi Donald,

Hi Jerry,

As you know, in a private real estate transaction the only "must" (for something like this) is what the two parties agree to, which can range from everything to nothing.

Be well,

Corey,

I suspect that Donald was referring to when the house is constructed, not to the current real estate transaction where the home inspector is pointing out what was not done when it should have been done.
