Switchboard control and meter wiring standards must meet which NEC requirement?

The correct answer is based on NEC Section 110.16, which addresses the requirements for switchboards and panelboards, particularly focusing on the marking of equipment that contains live parts. This section emphasizes the need for proper identification and marking to ensure safety and compliance, especially in areas where there is a potential for electrical hazard. When it comes to control and meter wiring associated with switchboards, adherence to these marking requirements is crucial for ensuring that those working on or around the equipment can recognize potential risks and hazards.

Additionally, Section 110.16 requires that equipment is marked to indicate the presence of live parts, thereby helping to prevent accidental contact. This standard is particularly important in the context of switchboard control and meter wiring because it helps ensure that workers can recognize the operational characteristics and safety protocols necessary for safe interaction with the equipment.

This understanding of NEC Section 110.16 is vital for anyone dealing with electrical installations, ensuring that not only are the physical installations completed correctly but that they also adhere to safety standards designed to protect individuals and infrastructure.
