If a branch circuit is installed using metal conduit serving as the Equipment Grounding Conductor (EGC) and a bonding jumper is installed around a short section of flexible nonmetallic conduit, the jumper is in ___ with the EGC.

The concept involved in this question pertains to the configuration of electrical pathways in grounding systems. In electrical installations, especially involving the Equipment Grounding Conductor (EGC), it is essential to understand how grounding components interact with one another to ensure safety and effectiveness.

When metal conduit serves as the EGC in a branch circuit, it provides a continuous conductive path back to the ground. If a short section of flexible nonmetallic conduit is present, it cannot serve as an effective ground. Therefore, a bonding jumper is sometimes added around this nonmetallic section to ensure continuity of grounding.

The bonding jumper creates a pathway that connects with the existing EGC when the metal conduit is connected. This means that both the EGC and the bonding jumper share the same current paths and are thus linked to each other. In this arrangement, the jumper operates in conjunction with the EGC to maintain a cohesive grounding system.

The term "in series" is relevant here because the bonding jumper directly connects to the existing grounding circuit, allowing current to flow through both the EGC and the jumper as a single pathway. This interplay enhances the safety and reliability of the grounding system by ensuring all components participate in conducting fault current as required.

Choices suggesting "parallel" would generally refer to
