Service entrance grounding question

[ggunn]

I remember some time back seeing language in the NEC which required the neutral to be bonded to the enclosure in a service entrance disconnect. I'd like to find it again to get the exact wording, but I don't remember where it was and I can't seem to find it. Can someone point me to it?

250.24


(C) Grounded Conductor Brought to Service Equip- ment. Where an ac system operating at 1000 volts or less is grounded at any point, the grounded conductor(s) shall be routed with the ungrounded conductors to each service dis- connecting means and shall be connected to each discon- necting means grounded conductor(s) terminal or bus. A main bonding jumper shall connect the grounded conduc- tor(s) to each service disconnecting means enclosure. The grounded conductor(s) shall be installed in accordance with 250.24(C)(1) through (C)(4).

Thanks. I remember it somewhat differently, either due to aging memory or different wording in an earlier code cycle. I remember it just saying that the grounded conductor needed to be bonded to the enclosure and leaving the reader to infer that it meant that it was a ground to neutral bond.

Totally possible. It changed pretty close to the present wording in 2008.
