A __________ connection should be used for connecting the grounding bus to the electrical enclosure.

The connection made to ground the bus to the electrical enclosure is critical for safety and effective operation of the electrical system. A bonding connection is specifically designed to ensure that all components of the electrical system, including the grounding bus and the enclosure, have the same electrical potential. This helps to prevent electrical shock hazards and ensures a path for fault current to flow back to the source, which allows circuit protection devices to function properly.

Using a bonding connection means that it is secure and capable of handling the electrical influx that may occur during faults, ensuring that the electrical enclosure is safely grounded. This is vital in maintaining the integrity of the grounding system and protecting both the equipment and individuals from electrical hazards.
