250.4 General Requirements for Grounding and Bonding

Section 250-2 in the 1999 NEC was revised and relocated to 250.4. It now reads:

(A) Grounded Systems.

(3) Bonding of Electrical Equipment. Noncurrent-carrying conductive materials enclosing electrical conductors or equipment, or forming part of such equipment, must be connected together and to the grounded (neutral) terminal at the electrical supply source in a manner that establishes an effective ground-fault current path.
