Installation of cutouts on an electric pole

[sgayam]

I need guidance on safety codes that regulate the number of cutouts installed on an electric pole and required spacing between them.
I have an underground 4160V line coming up the pole. There is already one set of cutout and transformer installed on this pole. Now I need to install another tap on this incoming 4160V, which will go through cutouts and feed a pad-mount transformer. Please see the attached pictures and let me know if I can use the spare crossarm on the top. If so, please provide the code reference or literature.

Thank you

Is this under the scope of the NEC?
If so what articles in the NEC have you looked at?
You are asking a question on HV engineering and it would seem you should have in house standards for this.

 

[sgayam]

In-house standards are in place but didn't explicitly talk about this exact scenario. NESC Section 234B2A-Exception 2 made more sense to me. Do you concur?

Attached is the plan for design.

Concur?...again this is an National Electrical Code forum.
We have a one or two members here who are knowledgeable on the NESC, but that is not our focus

That exception you quoted doesn’t allow that unless you de-energized the entire pole.
Unless I’m looking at something wrong. Are those fuses feeding backwards?
