damaged romex sheath


100 feet of 6-3 romex pulled through the crawl space...fighting bugs, spiders and plumbing...stapled all in, junctions made, ready to foam the hole through the wall and i notice the cable sheath is ripped where it comes through the LB into the crawl space. *&^#@. None of the 3 conductor wires are rubbed but the ground wire has the paper scraped away about 1/2 inch. Can I tape the cable or do I need to cut and splice the whole thing?

Fearing the answer...

The ground in your 6/3 is sheathed? It's usually bare. Anyways, if it's just the outside sheathing of the cable that is scraped off and none of the individual conductors are damaged, yes you can simply tape the entire section very well with electrical tape. Make sure none of the individual conductors are damaged. (If the individual conductors are nicked in any way, then I recommend a splice.)

Well I thought the ground had a paper sheath but in any case it is showing about a 1/4 inch through the tear in the NM cable sheath. None of the conductors are damaged as far as I can see.

i'll have to go under there again and make sure no other damage exists to any of the other wires before I tape the cable.

Thanks.

Is any of this cable outside the house? Is the crawlspace a damp area?

Not outside the house. THWN in conduit outside.

Crawlspace is not wet, not completely dry. Its earth in perpetual shade covered with layers of plastic. So yes damp.

NM cable is not listed for use in damp areas.

Type NMD90 cable, which is what you apparently ran, may be used for both exposed work in dry locations or concealed work in dry or damp locations. But yeah, in this case your wiring is apparently exposed in a damp location, therefore you need NMWU to be code compliant.

Lets call it temporary damp. It will be dry (as defined in NEC) during most of the year.

Humidity does not make a location "damp", small amounts of liquid water do. I doubt the overhead area in a crawl space qualifies as a damp location.
