Why is it important to ensure all metallic parts are bonded together?

Ensuring that all metallic parts are bonded together is crucial primarily to reduce the risk of electric shock. Bonding refers to the process of electrically connecting different metal parts to ensure that they have the same electrical potential. This is important because if there is a fault in the system, such as a short circuit, the bonded parts will help to redirect fault currents safely to the ground rather than allowing those currents to pass through a person who might come into contact with unbonded metallic components.

When bonding is properly implemented, it minimizes the likelihood of dangerous voltage levels appearing on accessible metal surfaces. This is especially vital in environments where electrical equipment is present and where individuals may come into contact with ground or metal structures. As a result, effective bonding contributes significantly to personal safety, helping to ensure that the risk of electric shock is mitigated. Proper grounding and bonding practices are essential components of electrical safety standards.
