Re: Parking lot pole
It depends, how many branch circuits will the pole contain?
More than one branch circuit? If so yes it does.
Why? I have no idea.

Re: Parking lot pole
250.32(A)?
250.32(A)?
Re: Parking lot pole
John, 250.32(A) is kinda relative, but unless the pole was served with two or more grounded conductors, or more than two ungrounded conductors, (single phase) or three ungrounded conductors, (three phase) we are only talking about one Multiwire circuit.
This is a case where 225.7 can apply to help explain the sentence above.
BTW, conductors passing through would not be serving the pole.

Re: Parking lot pole
I am with you Roger most times it will not be an issue.
A couple of times it could come up.
A 120 outlet on the pole along with the lighting.
We also do some lots that have 2 separate 480 volt circuits running the lights, redundancy for maintaining lighting.
Now why does an extra circuit change the need for an electrode?

Re: Parking lot pole
Hello Roger
The reference to 250.32(A) was sort of a hint that the question of whether or not a light pole could be called a "separate structure" has been discussed before in another thread.

I will stick with "It is"

Re: Parking lot pole
But a change in the 99 NEC clarifed that a lighting pole, even though it is a structure, does not require a disconnect at each pole. You can have a mulitwire wire circuit to a structure and not require a grounding electrode, the 05 NEC makes that clear.

Re: Parking lot pole
Maybe the exception to 250.32(A) could be modified to allow other circuits (like the 120 volt receptacle) on lighting poles without a grounding electrode?
