Code Q&A

Q. I heard that the Code only permits one equipment grounding (bonding) conductor to terminate on a grounding block screw terminal. Is this true?

A. No. The number of equipment grounding (bonding) conductors permitted to terminate on a grounding terminal is limited in accordance with the equipment manufacturer’s instructions [110.3(B)] posted on the label located inside the panelboard. However, two and sometimes three equipment grounding (bonding) conductors can generally be terminated to a single terminal. But be careful, because only one grounded (neutral) conductor is permitted on a single terminal (408.21).
