What describes the connection between the grounded circuit conductor and the equipment grounding conductor at a separately derived system?

In a separately derived system, the connection between the grounded circuit conductor and the equipment grounding conductor is specifically referred to as a Bonding Jumper, System. This designation is crucial because a separately derived system typically involves generative sources, such as transformers, that are isolated from the primary source. The bonding jumper serves to bond the neutral (grounded circuit conductor) and the equipment grounding conductor at the point of connection, which is typically at the service entrance or the grounding electrode.

This connection ensures that under fault conditions, there is a low-resistance path back to the source, which improves the safety and effectiveness of protective devices such as circuit breakers or fuses. By establishing this bond, it helps to clear faults and minimize shock hazards for individuals working on or near the equipment.

The other terms provided do not accurately describe the connection in this context. A bonding jumper, main typically refers to connections at the main service entrance for general bonding purposes. A bonding jumper, circuit would imply connections made within a branch circuit, which do not apply to the context of a separately derived system. Similarly, a bonding jumper, equipment is pertinent to grounding equipment but does not specifically address the crucial relationship between the grounded circuit and the equipment grounding conductors in a separately derived system
