§2742.3. Methods of Grounding Fixed Equipment.


(a) Noncurrent-carrying metal parts of fixed equipment, if required to be grounded by these orders, shall be grounded by an equipment grounding conductor that is contained within the same raceway, cable, or cord, or runs with or encloses the circuit conductors.

EXCEPTION for DC circuits only: The equipment grounding conductor may be run separately from the circuit conductors.

(b) Electric equipment is considered to be effectively grounded if it is secured to, and in electrical contact with, a metal rack or structure that is provided for its support and the metal rack or structure is grounded by the method specified for the noncurrent-carrying metal parts of fixed equipment in subsection 2742.3(a).

(c) For installations made before April 16, 1981, electric equipment is also considered to be effectively grounded if it is secured to, and in metallic contact with, the grounded structural metal frame of a building. When any element of this branch circuit is replaced, the entire branch circuit shall use an equipment grounding conductor that complies with all other provisions of Article 6 of these Orders.
