Hi All,

Need to run 90' overhead triplex wire. Have a telephone pole on one end. This run goes to an old barn as need to replace. Old run was 150' to another pole. I'm shortening the run, but would like to use pressure treated post instead. 6x6x16 is what I'm thinking. Will that be enough to hold that load?

Thanks,
David

If you put 4' in the ground that only leaves 12'. This will be much less in the center between post, probably close to 8'.

Any local lumber yard should have 20' 6x6 or longer. Either way you should use a guy wire to anchor the back side of the pole with only 4ft in ground.

Why not go underground?

Get a 20' 6x6 or larger put it 5" in the ground and put a slight rake away from the existing pole. You wont have to use a guy wire and anchor this way. Attach your new wire one foot from the top of your new post and leave about one foot or more of slack in your new wire. This will have less tension on your new post and have some expansion and contraction room.

IMHO, you will be well served by avoiding the minimum specification post. A margin for error has saved me more than a few times.

Check with the local Puget Power lineman yards, they should have used poles for little or nothing.

I've . moved this to the Electrical Section. Some of the guys here deal with this daily.

What is this wire for?

If this is a feeder for a subpanel off of a main service panel, you will need 4-wires not 3.

Running lights and a couple outlets from essentially the house to the barns. Replacing existing to the 'old' barn, then new run to newer barn to add lights and an outlet.

Would love to go underground, but septic line and a couple unknowns are in the way.

In the end, overhead will be easier. Another thought is to run to first pole, go inside, run it to other end of barn, then back up to the other pole to run overhead to the 2nd barn?

Thanks Dennis, I will check with Puget Power. Suppose Snohomish PUD as well.
