2.5” nipple on meter pan

[Bogiedown170]

Hi, I’ve looked at NEC and cannot find and need help understanding if a 2.5” offset nipple can be used on a meter pan for Rigid.
Basically we installed a 2.5” meter hub for a 2.5” rigid but as you can see from picture, we could not get the opening on roof close enough and gap from meter pan to bottom of roof line gradually separated to approx 3”.

the alternative was to use a 2.5” meter hub then attach an offset nipple and pipe would have been spaced evenly from pan to bottom of roof line. Is there anything in code that prohibits this? I’m in NY, Westchester County

Short answer is no because the offset nipple has straight threads and cannot be threaded into a rigid coupling. You need to offset the RMC.

Can't thread the straight thread of the offset into the meter hub either for same reasons.

I likely would have spaced the meter off the wall, probably with some unistrut.

Residential only guys are allergic to commercial industrial things like conduit and unistrut though. Service mast when needed is almost the only conduit some them ever use.

Yes into the hub is an issue also due to the threads. IMO unistrut on a house looks horrible.

Also the enclosure below the meter seems to be in the dedicated space required for the meter.

Really need to bend an offset into the ridged just before the roof penetration as the ridged is acting as a mast support for the service drop, and thus would prohibit the splice above the last attaching point to the building. So putting anysort of mechanical offset coupler above attaching points would be violation. And I dont know of a compression coupling qualifies as electrically continuous for the metal riser mast requirements.

Thank you for the responses and options. Will do better on the next job.

Just had to bring the meter out over 3” off the wall yesterday, non-kit log cabin, logs varied widely, then to top it off, metal roof v right where I needed to penetrate! Double strut.

Strut can be cut so it doesn't extend past the side walls of the meter cabinet and it would hardly be noticed. can even be painted if you don't like the color. Quite frankly nobody wants the meter on the house either but sometimes you have little or no choice on that.

Does mete need "dedicated space"? and if so that (presumably electrical) enclosure is still not sticking out beyond 6" of the front of the meter cabinet.

If a local POCO has additional rules that could be a problem, but I don't see anything here that violates NEC.

If this industrial/utility look is totally undesirable, underground supply eliminates many the exposed items on the house, or even all of it if you can enter below grade. Even in 2020 NEC, that outside emergency disconnect can be elsewhere on the premises it doesn't have to be on the house.

Should go back and fix it that will be an eye sore for a long time.
Assuming you have a roof Jack. Pull it up and cut the roof back to your 3”, will make it look better, Jack should still cover. Then seal Jack off.
Might look bad if you look up at the eve, but that is less noticeable, and easy to fix

Notch the freeze block between the rafters. box it out with wood and paint is what we do

I have to sort of disagree. While the instructions/ listing of some things does only seem to allow mating with certain other things, I am skeptical this is because of a different thread type. I have never seen that stated anywhere (except forums). Besides there are things such as reducers and increasers that have straight threads. Furthermore, couplings of course have straight threads and are mated with tapered threads, so I don't see the logic in saying male taper to female straight ok but male straight to female straight not ok.

It is what it is. I disagree with what is said in this article but this is a lead engineer for UL.

Fittings into Hubs

Recently, i witnessed an electrical inspector and a group of electricians discussing the effectiveness of the bonding and grounding path where raceway fittings are used to connect raceways to threaded hubs, threaded bosses or conduit bodies. Although this is a fairly common practice in the...
