ECN Forum Forums General Topics of the Trade General Discussion Area Service Lateral

A service lateral originating at the Power Company pad mounted transformer secondary terminals will be installed in PVC. Voltage system is: 277/480V, 3Ph, 4W.
Am I correct in thinking an equipment grounding conductor is not required from the transformer to service disconnect.
I don't think it is a requirement.

Frank,
You are correct, an EGC is not required on the line side of the service disconnect. The grounded conductor is used for all equipment grounding on the line side and within the service disconnect enclosure.
