I will be running power from a house to a well house/shop. I have a roll of
8/3 w ground and 6/3 with ground submersible wire that I used in well pump
installations. Since I have no further use for these two rolls, I'd like
one of them instead of UF. Is that ok if I put the wire in conduit?
Since you don't tell exactly what type of wire the 8/3 is, and the
description of the 6/3 is, perhaps, a bit limited, I don't think you
can get an authorative answer.
FWIW, conduit has nothing to do with it--you will need conduit
regardless if you're burying cables.
I am a "seat of the pants" electrician, but know very well that any direct
burial of cable or wire is a no-no. I would say that putting your cable in
a conduit would only protect it, and not be a problem.
Now I read on:
Here is what I found:
Technically you can't run ROMEX in conduit except for short pieces for
protection (like through walls or floors).
You also technically can not simply strip the jacket of the wire and run it
in the conduit (the wire is Romex are not LISTED for use).
I've never heard of Romex wire causing sweating inside conduit. Any conduit
underground will "sweat" inside. Since you ran outdoor Romex (Do you mean
UF??) that would suggest it is water proof, and therfore being in a "sweaty"
conduit shouldn't be a problem.
Leaving romex exposed is never a good idea (weed wacker??). Personally I'd
leave it as is. If you want to be to code, then you'll need to get some
black, white, and green THHN/THWN wire and pull out the romex, and put this
in its place.
If this is downhole wire for submersible pumps, I think it would be
better than anything you could get. In conduit.
UF is for direct bury. Your inspector/entity may not allow it but that
is what is designed for.
*If the 6/3 is approved for wet locations it can be put in conduit
underground. It should have a "W" in its letter designation. Regular wire
and cable without the wet location approval is not permitted underground
even in conduit. Condensation builds up inside of underground conduit.
Thanks guys. Yes this wire is used down water wells and you can't get any
wetter place than under water. It is made up of four twisted individual
wires with out a common jacket. The colors are black, white, yellow and
I'm curious what type of cable is this? Is there any letter designation on
the outer jacket or inner conductors? I would think that it would have to
be like a portable flexible cord to allow for the installation and removal
of a well pump. Though it may be approved for wells does not necessary make
it approved for anything else.
Typical product sheet for the type. This one happens to be 3-conducter
twisted instead of 4 and some are flat (similar to light cord except
more/larger conductors) w/ separable strands for termination ease.
Strictly speaking, no it isn't intended/rated for burial but it'll
likely last a long time.
So, while can't recommend it as Code-compliant, it's one of those that
if OP is in area that doesn't require absolute conformance/inspection it
will serve the purpose.
*With that designation I would say that it is only approved for submersible
pump use. I did read the link furnished by dpb and it sounds as though that
cable could be used for what you intend. However the final determination
will be made by the electrical inspector. I suggest that you ask him before
