18.2 Bonding

18.2.1 A noncurrent-carrying metal part shall be bonded to the point of connection of the grounding

conductor. For a pump equipped with a box for supply connections that is remote from the motor or pump,

a green colored lead in the interconnecting cable, terminated as described in 18.1.2, may be used for

bonding. A submersible deep-well or shallow-well pump may be provided with a green-identiﬁed deep-well

cable conductor the same size as the circuit conductors or with terminals on both the outside of the pump

housing and the inside or outside of the supply connection box (when provided). The grounding terminal

shall comply with the requirements in 18.1.4.

accomplishing bonding and grounding shall penetrate all nonconductive coatings such as paint.

18.2.3 A bolted or screwed connection that incorporates a star washer under a screw head, a serrated

screw head, or the equivalent is acceptable for penetrating nonconductive coatings as required by 18.2.2.
