when is it required to install a ground rod for each light pole in a parking lot??

You might want to read the definition of "Structure" in article 100 and then read 250.32 before you say never.never. not a required code, unless its called for in the plans
Roger brings up an interesting point if the "structure" is served by more than one circuit.
Not really, it meets the definition wording and an inspector would certainly have a strong point.That's quite a stretch to consider a light pole structure...
It is a single circuit, current is flowing in and out of each conductor to complete the circuit.also does a 2 pole 208 volt circuit to a lightpole considered one or two circuits?

I was about to bring up that dead horse, but I figured it had been beaten enough! :lol:

225.32 Location. The disconnecting means shall be installed
either inside or outside of the building or structure
served or where the conductors pass through the building or
structure. The disconnecting means shall be at a readily
accessible location nearest the point of entrance of the conductors.
For the purposes of this section, the requirements
in 230.6 shall be utilized.
Exception No. 3: For towers or poles used as lighting
standards, the disconnecting means shall be permitted to be
located elsewhere on the premises.

Yes a light pole could be called a structure, and as we know every structure requires a disconnecting means per 225.32 However 225.32 EX 3 does not require a disconnecting means at each pole, so no disconnect, no ground rod.
Tom, as Bob points out, the disconnect exception is not tied to the need for a ground rod.However 225.32 EX 3 does not require a disconnecting means at each pole, so no disconnect, no ground rod.
Gentlemen, the only reason for a ground rod at a light pole would be for lightning protection. I is not required by the NEC. If installed it won't hurt anything; but I don't know why anyone would want to spend all that extra money. It might be in the job specifications.
Where some electricians get into trouble is when they think they can drive a ground rod at the pole in place of running the equipment grounding conductor with the circuit conductors. This is dangerous and is a serious code violation.
So, the question is, do you still believe your original statement?LOL.... look at the hornet's nest I started by saying never.
