I want to run a simple 120V line on my farm from the garage to a shed.
All its for is a few lights and one outlet in case I want to run a
power tool. So, it's nothing much. Just a simple 2 wire 20A run. I
need to go about 80 feet. There was an old pole building that I tore
down in between the garage and shed, but I left one of the tall poles,
since I was planning to run this wire. That pole is about dead
center, so there will be about 40 ft. one each side of the post. All
I really need is a piece of 12gauge romex, but I know that wont hold
up outdoors. I can NOT go underground, because there is an old
concrete slab there. So, I must go overhead. What is the smallest
gauge triplex they sell? (I dont think they make a 2 wire cable, so I
may as well use the 3rd wire for a ground), since there will be no
breaker in the shed, just a 20A breaker in the garage. I must also
mention that I want to keep costs down, and have considered running 2
separate wires like they did in the old days, but I am not sure what
type of wire is made for outdoor use. What other options are there?
I am NOT worried about code, because around here no one really bothers
with code. However, I do want it safe, and for the last few years I
have had a few extension cords strung across, and am not too happy
with that, especially when it gets unplugged up on the pole from
winds, and I know that is not safe.

My other option is to buy some heavier USED triplex from a local guy
that demolishes buildings, and re-sells a lot of stuff. He always has
that sort of thing around. The last time I was there he had some that
was thinner than most of the stuff I am familiar with, but still much
thicker than a #12 wire. There was no markings on it, so I am going
to guess it to be a 4 gauge (wires are about 1/4" thick WITH
insulation. Is there any way to measure the wire to determine the
gauge? The reason I need to know, is because he sells this stuff at
half the price of new, and I want to be sure he is using the right
gauge for the price, because this guy is not the most honest.

The other thing, I know that underground cable (UF) is not made for
overhead, but I believe it is sunlight resistant, That makes me
wonder if that is all I really need to string across?

Thanks in advance for all help.

The smallest over head triplex I have ever installed was #2. Try King Wire,
Anixter, or Standard Wire locally to you. Ask for end of rolls.
Call your local utility and ask them if they have a piece that they will
sell you.

1/2 of new is good if you can get it. If you want this to last stay away
from UF. Even with sunlight resistant it will not hold up like the other
stuff.

For an single circuit you need to carry the ground and the ASCR messenger is
good for that. Warning cut this stuff with bolt cutters, not cable cutters.
The center is steel. I have seen more than one person ruin an good rabbit
gun by cutting the messenger.
