Has anyone else ever heard that on a service mast, you can't have a coupling above roof line or above last strap? Is that just a poco requirement or is there something in the code I didn't see?
 
Chevy art. 230.28 -- I guess one could interpret that loosely but a coupling above the roof will be a weak link and I would say is not adequately supported. The specific rule may be a podco rule... I don't know
 
I'd NEVER put the coupling at the top. The cut piece always goes at the bottom. I don't think it's in the code, but it might be a POCO requirement. I call it common sense.

I agree about it being weak. I questioned an install today and couldn't find anything in code to back it up.
 
I agree that the general rule about the mast being strong enough should keep someone from doing this. IMO the coupling is a very weak point and shouldn't be relied upon to hold up the service drop. I have seen it quite often however.
 
ga power doesn't allow us to put the coupling at the top either. cut piece goes into hub, then coupling, then full stalk.

A lot of times it ends up at the top since a lot of guys don't have a 2" threader.

I dunno... the regular ordinary 12r die set goes from 1/2" to 2", so it's not like it's a special or odd sized threading die. I only put up 2-1/2" masts, so that takes the hog-head threader. I measure masts during the sales call, so that they piece can be threaded at the shop and sent along.

An electrical contractor with out a 2" threader????? :-? Probably a magnetic sign on the door of the 1962 window van that reads "Hectic Electric, Contractor".....:D

I take that personally.:D I must be a Hectic Electric. I bet many residential guys around here don't have them.

I have been in the business for 30 years and have never needed a 2" threaded. Not all contractors work with the big stuff. If I use 2" galvinized, it is for a mast and it goes straight up through the roof. I can't think of the last time I used 2" Galvinized.

It's hard for me to imagine 30 years of going thru the roof with 2" conduits and never having to cut a piece and thread it. :roll: Sorry If I offended you, that was not the intent....the intent was more along the line of reflecting my personal experience with unskilled and improperly trained and outfitted "contractors" entering the trade prematurely....:)

You did not offend me at all. That's why I put the smiley face. Most everything we do is underground and I probably have had less than 10 jobs with galvinized through the roof. You cut the end with the weatherhead and you don't have to thread it.
 
If I didn't own a 2" threader, (I do), I would bring a variety of 2" RMC nipples to do a service job involving RMC mast. Around here almost all service upgrades are overhead so a mast is a common installation.

In the town of Chapel Hill will I live and work they have a town ordinance so you must change over from overhead to underground if you do a service upgrade. Plus every developemnt is underground.

How would you go from overhead to underground if the poll was on the other side if the street?

That's podco's problem. Remember it is all overhead at the street so they would probably set a pole at the street then go underground from there. They could drill under the street but I have not seen them do that lately.

We can do that too, but the HO has to pay for the new pole on their side of the street. Who pays for the pole over there?
