342.30(B)(2) ? - coupling in svc mast

[dana1028]

Regarding a coupling in an IMC [or Rigid] mast...above the roof - see photo. I know the utilities prohibit this installation [at least mine does].

Is there a specific code section that would also apply? I'm looking at 342.30(B)(2) - does that work?

thanx

No specific NEC prohibition. This one is open to interpretation as to whether or not the section above the coupling is of adequate strength. IMO it's not. Here's the section that you should take a look at:

230.28 Service Masts as Supports. Where a service mast
is used for the support of service-drop conductors, it shall
be of adequate strength or be supported by braces or guys
to withstand safely the strain imposed by the service drop.
Where raceway-type service masts are used, all raceway
fittings shall be identified for use with service masts. Only
power service-drop conductors shall be permitted to be at-
tached to a service mast.

Check with your POCO, they may well have additional rules.
