Thread: Feeders in crawl space

Town home built in the mid 80's. The freeders are running through the crawl space and lacking support as they penetrate the sub floor. Are these rated for this type of installation. I see a W in the rating.

I wouldn't want to be in a Wet Crawl With them Things.

But if I'm reading right they are Rated for Underground Use.

TYPE USE-2/RHH/RHW-2
.

I do not have the reference handy, but I believe that individual conductors should be in a conduit.

If the cable is being used as service entrance cable it has to follow the rules for USE type wire. USE is NOT permitted in the interior of a residence as it is not a fireproof or fire resistant cable.

338.12 Uses Not Permitted

(B) Underground Service-Entrance Cable.

Underground
service-entrance cable (USE) shall not be used under the
following conditions or in the following locations:
(1) For interior wiring
(2) For aboveground installations except where USE cable
emerges from the ground and is terminated in an enclosure
at an outdoor location and the cable is protected in
accordance with 300.5(D)
(3) As aerial cable unless it is a multiconductor cable identified
for use aboveground and installed as messengersupported
wiring in accordance with 225.10 and Part II

of Article 396

300.5 Underground Installations.

(D) Protection from Damage.

Direct-buried conductors
and cables shall be protected from damage in accordance
with 300.5(D)(1) through (D)(4).

(1) Emerging from Grade.

Direct-buried conductors and
cables emerging from grade and specified in columns 1 and
4 of Table 300.5 shall be protected by enclosures or raceways
extending from the minimum cover distance below
grade required by 300.5(A) to a point at least 2.5 m (8 ft)
above finished grade. In no case shall the protection be
required to exceed 450 mm (18 in.) below finished grade.

(2) Conductors Entering Buildings.

Conductors entering
a building shall be protected to the point of entrance.

(3) Service Conductors.

Underground service conductors
that are not encased in concrete and that are buried 450 mm

(18 in.) or more below grade shall have their location

identified by a warning ribbon that is placed in the trench at
least 300 mm (12 in.) above the underground installation.

Where the enclosure
or raceway is subject to physical damage, the conductors
shall be installed in rigid metal conduit, intermediate metal

That would be correct Gunnar.
