Electrician's Licensing Practice Exam

To bond a motor conduit with metal flex, it is essential to install a bonding jumper either inside the conduit or outside of it, but within 6 feet of the attachment point. This is important for ensuring electrical continuity and safety by reducing the risk of electrical shock or fire due to faults. The bonding jumper facilitates a low-resistance path to ground for fault currents, which helps protect both equipment and personnel.

When bonding, the placement of the jumper within the first 6 feet of the attachment point assists in maintaining the effective grounding of the equipment. The NEC (National Electrical Code) emphasizes the need for proper bonding of metal raceways and enclosures to ensure that any fault currents can be safely directed back to the grounding system.

This approach also adds flexibility in installation requirements, as it allows electricians to choose the most suitable method for a specific application while adhering to safety protocols.
