Grounding Outdoor Sub-Panel

Sander1February 25, 2012

We have a Meter and a main disconnect with Ground; at 130' distance we plan to install an outdoor sub-panel. would it be right to run 2 hots and 1 neutral to the sub-panel and use a Ground Rod for Grounding the sub-panel? ...Thank you!

Under the newest NEC all sub-panels require a 4-wire feed.

The exception allowing a 3-wire feed to another structure if no other metallic connections are present was removed.

If the sub-panel is attached to the same structure it has required a 4-wire feed for a very long time.
