What does the equipment bonding jumper connect in a device outlet box?

The equipment bonding jumper serves a crucial role in electrical systems by ensuring a continuous path for electrical current to flow in the event of a fault. Specifically, in a device outlet box, it connects grounding conductors to the receptacle terminals. This connection is key for safety, as it helps to prevent electric shocks and ensures that any stray electrical faults are safely directed to the ground.

By connecting the grounding conductors to the receptacle terminals, the equipment bonding jumper ensures that any metal parts of the outlet or connected devices are grounded. This grounding helps to protect users by minimizing the risk of electrical shock should there be an insulation failure or fault in the device. It also contributes to the proper functioning of circuit breakers or fuses that are designed to trip in the event of a fault, further enhancing the safety of the electrical installation.

The other options either pertain to connections that are not directly relevant to the outlet box or do not accurately describe the function of the equipment bonding jumper.
