For a metal vent 15 feet high with 2 down conductors, what is the bonding distance?

The bonding distance for a metal vent is determined based on its height and the number of down conductors. In this case, since the vent is 15 feet tall and has two down conductors, it falls within the criteria that specify how far the bonding point needs to be from the vent.

The bonding distance is defined as the distance from the base of the vent to the bonding point on the conductors. For structures reaching a height of 15 feet, certain guidelines dictate the appropriate bonding distance, which in this instance is established as 1 foot 8 inches. This ensures adequate grounding and safety, minimizing the risk of electrical hazards.

Utilizing this standard helps to maintain compliance with safety regulations and supports the effectiveness of the grounding system. Therefore, recognizing the specific bonding requirements for structures of this height is essential for ensuring overall electrical safety in environments where explosive materials may be present.
