Horizontal Weatherhead Against Wall or LB at Weather Heat


Hi Everyone,

I'm just about finished with my electrical upgrade.

The red in this picture is how the conduit is being run, it is all 2" galvanized rigid:


How should I connect the weatherhead?


Should I just ad it at the end of the horizontal run? Will that even work being against the wall?

I was thinking of using a LB (or an LL) and, using a nipple pointing up, have the weatherhead in the usual orientation.

Is an LB at the end near the weatherhead OK (per code)?

I would just use a regular 90 degree sweep, but it would put the weatherhead too far from the service hook up.

What you you guys do/suggest?

Thanks!

You should put a "kick" (small 20 degree or so bend) in the pipe. That will
give you the clearance from the wall you need. You do however need access
to a rigid pipe bender in order to do this. Also why not use rigid pvc pipe
instead of metal. It is much easier to bend!

PVC is not allowed here.

By a 20 degree "kick" do you mean away from the wall (still parallel to the ground; still horizontal) or angling slightly vertical?

If you mean away from the wall so the pipe is still horizontal, will that be water tight? Seems like it wouldn't.

I should have someone coming to bend 2 pipes for me in the next few days. I'm trying to figure out the measurements before he gets here, and need to know how far from the end the bend will be, if I need to leave room for an LB.

Yes kick away from the wall and. It would be watertight the same as if it
were a vertical pipe,you just have to adjust the weatherhead facin down so the wires form a drip loop before they enter the weatherhead. you should leave approx 3ft of wire hanging from the weatherhead so when the utility connects to it they can form the drip loop.

The only weatherheads I've seen are bolt clamp on. Couldn't water get in between the pipe and weatherhead? Is there a gasket at the connection or a watertight version?

I'd be looking into have the line ran underground to get rid of all that ugly mess.

Too late, and too much $ anyway. I'm doing it all myself (except for someone with a bender), including a meter base with disconnect included and new panel, wire, etc, for a hair over $1000.

So I just purchased a bolt on service entrance cap...

It definitely looks like it is NOT intended for the horizontal position.

So, is there anything WRONG with using an LB at the end of the conduit run near the cap?

hmm.. I think I figured it out...

I'll just have a bend at the end of the horizontal run that is ~ 20 degrees away from the wall AND ~ 20 degrees north of horizontal.

Sound feasible?
