wire

| Neither is for direct burial. There is a direct burial conductor that you
can get in #2 though. I'm thinking it's XHHW,or just possibly UF, but just
ask for direct burial #2 copper at an electrical supply. I do think UF cable
is made in #2 as well

I do not believe either is rated for direct burial. UF is. thhn is
rated for "dry locations" and thwn is rated for "wet locations". So,
thwn will have to go in conduit. you'll need a min of 1'' pipe to run
more than 1 #2 wire. Call local electric supply house to verify.

you want # 2 USE2........ its underground service entrance cable....
go to an electrical supply house...tell them what you want to do...they
will sell you the correct wire.
wire is ultra expensive now......bet that number 2 is going to cost a
bundle.

I've buried a lot of wire, and I wish I had used conduit. Conduit makes
repair/additions much easier. You will eventually wish you had spent
the extra money and used conduit.

wire
thanks for the help on this. the guy at home depot told me thhn was for
direct bury. i have already buried a 2 inch conduit but want to run a
cable that is rated for direct bury so i dont have to worry about the
integrity of the conduit leaking later on. i will go to rexall electric
in the morning and see what they have. this is going to be a 200 ft run
to a sub panel i will have to use 3 wire with ground and with the cost
of copper i dont want to have to do it a second time.thanks for the
help scott

Home Depot clerks are just clerks. The wire they sell is THHN/THWN
dual rated conductor. It is OK for a wet location (in the buried
conduit) but not direct bury. All buried conduit is a wet location and
it will ALWAYS end up with water in it. You are fine wth the
THHN/THWN.

with a 200 foot run go to a much heavier conductor even if planned
loads are low like lights.
one day you may want to use say a circular saw and a 200 foot run is so
lossy it will effect saw performance.
with copper so pricey this will cost a fortune
