Exposed noncurrent-carrying metal parts of an information technology system shall be what?

Exposed noncurrent-carrying metal parts of an information technology system should be bonded to an equipment grounding conductor to ensure safety and proper functioning of the electrical system. Bonding connects these metal parts to the ground, which helps prevent any build-up of electrical charge and provides a low-resistance path for fault currents. This minimizes the risk of electric shock and enhances the overall safety of the equipment and personnel.

In electrical safety codes and standards, grounding is essential because it mitigates electrical hazards by directing any stray currents safely into the ground, thus protecting people from potential electric shock. It also helps in stabilizing voltage levels within the system, ensuring proper operation of the equipment.

While insulating noncurrent-carrying parts, ensuring that safety devices are used, or employing double insulation are important safety measures in various contexts, bonding to an equipment grounding conductor is the specific requirement for exposed metal parts under the relevant electrical safety standards.
