A(n) _____ shall be used to connect the grounding terminal of a grounding-type receptacle to a grounded box.

• A. Equipment bonding jumper
• B. Grounding conductor
• C. Pigtail
• D. Splice

Answer: (A)

Bonding metal parts to keep a continuous grounding path is the key idea. For a grounding-type receptacle mounted in a metal box, you need a bond between the receptacle’s grounding terminal and the box so fault current has a low-impedance return path. An equipment bonding jumper is the short conductor used specifically to connect those metal parts together, ensuring the receptacle is properly bonded to the grounded box. The jumper provides a reliable bonding path even if other connections don’t make a perfect metal-to-metal bond. The grounding conductor from the panel is the larger path for fault current, but the equipment bonding jumper is the dedicated link that ties the receptacle’s ground to the box. A pigtail serves a similar bonding purpose in practice, but the standard term emphasized here is equipment bonding jumper. Splices are for joining conductors, not for establishing the grounding bond between the receptacle and the box.
