LB Conduit Body Mounting

[central1ny]

I am installing an LB conduit body on the outside of the house below a new meter socket. What is the proper way to mount the conduit body? The house has vinly siding so I was planning on mounting a J-Block behind the conduit body and somehow mount the conduit body to the J-Block. But there are a couple of concerns.

First off, the conduit body has neither mounting tabs or mounting holes. Is it acceptable to drill holes in the conduit body or would this violate an NEC code? If this causes a violation, what can be done?

Secondly, the new meter socket is mounted such that the conduit body would need 1/2" spacers between it and the J-block. Any issues here?

Anyone have a better mounting method?

Conduit Bodies themselves don't need to be secured, they are considered part of the conduit and are only subject to the support requirements of the conduit.

Do you know the NEC section that would support this? I found 314.23 (E) , which seems to support this. Would you agree? The conduit body that I have is a Carlon E986J, 2" and measure approx. 84 cubic inches but does not have threaded entries. Since the meter socket is less 3 ft away and is securely mounted, I dont think I need any extra mounting clamps.


314.23 (E) Raceway Supported Enclosure, Without Devices,
Luminaires, or Lampholders. An enclosure that does not
contain a device(s) other than splicing devices or support a
luminaire(s), lampholder, or other equipment and is supported
by entering raceways shall not exceed 1650 cm3
(100 in.3) in size. It shall have threaded entries or have
hubs identified for the purpose. It shall be supported by two
or more conduits threaded wrenchtight into the enclosure or
hubs. Each conduit shall be secured within 900 mm (3 ft) of
the enclosure, or within 450 mm (18 in.) of the enclosure if
all conduit entries are on the same side.
Exception: Rigid metal, intermediate metal, or rigid nonmetallic
conduit or electrical metallic tubing shall be permitted
to support a conduit body of any size, including a conduit
body constructed with only one conduit entry, provided the
trade size of the conduit body is not larger than the largest
trade size of the conduit or electrical metallic tubing.

the exception does, but i think i remember it somewhere else too, but i don't have my book handy to look it up.
