What is one potential hazard of not bonding equipment enclosures together?

Not bonding equipment enclosures together poses a significant electrocution risk. Bonding provides a pathway for fault currents to safely reach the ground in case of a fault, such as a short circuit or insulation failure within the equipment. When enclosures are not bonded, there's a higher chance for the accumulation of voltage on the equipment surfaces, which can lead to electric shock if a person comes into contact with the enclosure while standing on a conductive surface or if they are grounded in any way.

Bonding mitigates this hazard by ensuring that all conductive enclosures are at the same electrical potential, minimizing the risk of electric shock. It creates a more effective grounding system, protecting both individuals and equipment from potentially dangerous electrical faults. Without proper bonding, the safety measures established by electrical codes and standards are compromised, putting workers and maintenance personnel at risk during operation or maintenance activities.
