This meter socket enclosure and other equipment were not going to come between a homeowner's new brick wall and wrought-iron fence and the existing property line.
The overcurrent devices may have been considered to bereadily accessible after removal of the fence bar, but this equipment with a permanent fence installed in front of it makes it a clear violation of the rules in 110.26.
Although I could not find any specific reference in Article 312 for working spaces, Article 408 may have an applicable rule. All that is really needed is the definition of “equipment” in Article 100. Equipmentis ageneral term including material, fittings, devices, appliances, luminaires (fixtures), apparatus and the like used as a part of, or in connection with, an electrical installation.
