Multiple branch circuits running through light bases ( spliced through at hand hole). 2 seperate circuits ( 480 volt heads )required at each base for reliability and 2 other circuits passing through to pick up other light bases.I take it as a light base is a structure.

This would be on a multi building facility, but does that apply to branch circuits? It is a requirement to apply l.o.t.o. before working on any circuit.

Are you concerned about having two circuits feeding each pole, or about the other circuits which feed through them?

My concern is both. The safety concern is no different than a j-box with multiple circuits. Is a concrete base a seperate structure and would 225.30 apply? If it is allowed, would a ground rod then be required?( 250.32(A) )
 
IMO there is no question a light pole or sign pylon are structures to the NEC and require disconnecting means per 225.31.

However Exception 3 and 4 to 225.32 allow these required disconnecting means to be located elsewhere.

If you have multiple circuits supplying the pole then you need a grounding electrode per 250.32(A). Keep in mind a multiwire branch circuit can be called one circuit.

Don't the poles have a ufer/ground wire in the concrete base?
