Background:
A meter socket is being installed on a unistrut metal frame (In a public Right of Way) to monitor the power flow to a battery unit charging station equipment. The voltage being provided to the battery charging equipment station is 120/240 volt three wire service.
The battery charging unit equipment will be mounted on the unistrut metal frame as well. It appears that according to the existing rules of the NEC a service equipment disconnect means has to be provided as per NEC Article 230.70. In addition, the main disconnect has to be grounded as well at this location as per 250.24 (A) and the unistrut metal frame can not be utilized as the grounding conductor means.
Am I interpreting the Current version of the NEC appropriately? Please advise and thank you for your advise
