Any pointers how to install that? What are the code requirements (how far can the pipe stick out, do I need to support the pipe with guy wire, where to mount mast etc?) Is that somewhere in code book?

It's funny you say that. There is a national wide shortage of meter sockets (like a month+ wait) and I was able to find one with horn bypass but neither electrical inspector or the utility company know what that is and therfore told me not to install it :)

Yeah, I wasted three hours of my life looking for a common (not so common) single phase meter socket last week. I eventually found a supplier who had two that had been robbed for parts so we built one out of two. Then I paid 50% higher than it was before.

As for meter sockets, have you tried looking in less than normal places?

Amazon, Walmart, eBay?

Yes. We are required to put level bypass on common area. But everything that I find online either has horn bypass or no bypass at all. But that's different service. The one that goes through the roof is a single meter, those are in stock. It's just I've only done this once and very long time ago. Don't want to do the job twice if there are some specific requirements. Ps I already emailed service engineer for that town....

You ask alot in one question. Here is the best I can do


230.24 Clearances. Overhead service conductors shall not be
readily accessible and shall comply with 230.24(A) through (E)
for services not over 1000 volts, nominal.
(A) Above Roofs. Conductors shall have a vertical clearance
of not less than 2.5 m (8 ft) above the roof surface. The vertical
clearance above the roof level shall be maintained for a
distance of not less than 900 mm (3 ft) in all directions from
the edge of the roof.
Exception No. 1: The area above a roof surface subject to pedestrian or
vehicular traffic shall have a vertical clearance from the roof surface in
accordance with the clearance requirements of 230.24(B).
Exception No. 2: Where the voltage between conductors does not exceed
300 and the roof has a slope of 100 mm in 300 mm (4 in. in 12 in.) or
greater, a reduction in clearance to 900 mm (3 ft) shall be permitted.
Exception No. 3: Where the voltage between conductors does not exceed
300, a reduction in clearance above only the overhanging portion of the
roof to not less than 450 mm (18 in.) shall be permitted if (1) not more
than 1.8 m (6 ft) of overhead service conductors, 1.2 m (4 ft) horizontally,
pass above the roof overhang, and (2) they are terminated at a
through-the-roof raceway or approved support.
Informational Note: See 230.28 for mast supports.
Exception No. 4: The requirement for maintaining the vertical clearance
900 mm (3 ft) from the edge of the roof shall not apply to the final
conductor span where the service drop or overhead service conductors
are attached to the side of a building.
Exception No. 5: Where the voltage between conductors does not exceed
300 and the roof area is guarded or isolated, a reduction in clearance
to 900 mm (3 ft) shall be permitted.
(B) Vertical Clearance for Overhead Service Conductors.
Overhead service conductors, where not in excess of 600 volts,
nominal, shall have the following minimum clearance from
final grade:
(1) 3.0 m (10 ft) — at the electrical service entrance to buildings,
also at the lowest point of the drip loop of the building
electrical entrance, and above areas or sidewalks
accessible only to pedestrians, measured from final grade
or other accessible surface only for overhead service
conductors supported on and cabled together with a
grounded bare messenger where the voltage does not
exceed 150 volts to ground
(2) 3.7 m (12 ft) — over residential property and driveways,
and those commercial areas not subject to truck traffic
where the voltage does not exceed 300 volts to ground
(3) 4.5 m (15 ft) — for those areas listed in the 3.7 m (12 ft)
classification where the voltage exceeds 300 volts to
ground
(4) 5.5 m (18 ft) — over public streets, alleys, roads, parking
areas subject to truck traffic, driveways on other than residential
property, and other land such as cultivated, grazing,
forest, and orchard
(5) 7.5 m (241∕2) over tracks of railroads



230.26 Point of Attachment. The point of attachment of the
overhead service conductors to a building or other structure
shall provide the minimum clearances as specified in 230.9 and
230.24. In no case shall this point of attachment be less than
3.0 m (10 ft) above finished grade.
230.27 Means of Attachment. Multiconductor cables used for
overhead service conductors shall be attached to buildings or
other structures by fittings identified for use with service
conductors. Open conductors shall be attached to fittings identified
for use with service conductors or to noncombustible,
nonabsorbent insulators securely attached to the building or
other structure.
230.28 Service Masts as Supports. Only power service-drop or
overhead service conductors shall be permitted to be attached
to a service mast. Service masts used for the support of servicedrop
or overhead service conductors shall be installed in
accordance with 230.28(A) and (B).
(A) Strength. The service mast shall be of adequate strength
or be supported by braces or guys to withstand safely the strain
imposed by the service-drop or overhead service conductors.
Hubs intended for use with a conduit that serves as a service
mast shall be identified for use with service-entrance equipment.
(B) Attachment. Service-drop or overhead service conductors
shall not be attached to a service mast between a weatherhead
or the end of the conduit and a coupling, where the coupling
is located above the last point of securement to the building or
other structure or is located above the building or other structure.
230.29 Supports over Buildings. Service conductors passing
over a roof shall be securely supported by substantial structures.
For a grounded system, where the substantial structure is
metal, it shall be bonded by means of a bonding jumper and
listed connector to the grounded overhead service conductor.
Where practicable, such supports shall be independent of the
building.

Is this for a residential or commercial service? Some building departments have guidelines above minimum requirements of the NEC.
Most Cities will give you information and sometimes sketches of how they want things.
There are all kinds of variable such as meter height, service drop height and so on.
That's why you need to wait for engineer before you start.
I'm not sure what the max height a service mast can be above the roofline but I do know you can't have any couplings above the roofline.

Here is a diagram for a residential service. It's just an example for members that might want to comment on.
It looks code compliant for a surface mounted panel but it might not be acceptable in your area.

I just purchased a dozen meters on eBay a few weeks ago. Was going to send a link, but all of the sellers are out of stock. There does seem to now be at least a low stock of meter bases.

Most utilities from what I can tell are now requiring lever bypass meters and don't allow horn bypass at all on new services.


This is the utility for most of the area where I work.
