The National Electrical Code (NEC) is a set of safety rules governing the installation, maintenance, and use of electrical equipment. This code requires manufacturers of electrical equipment to clearly mark their products with their name, trademark, or other descriptive marking, so that the organization responsible for the product can be identified. The marking must also be durable enough to withstand the environmental conditions it is exposed to. Additionally, the code requires that equipment ratings (such as voltage, current, wattage, etc.) be clearly marked on the equipment and that these markings be located so they are visible or easily accessible during or after installation.
These requirements are in place to ensure that all electrical equipment is correctly rated and installed in a way that will not cause harm to the users or the equipment itself. By clearly marking the equipment, it is easier for electricians to identify the product and ensure that it is properly installed according to the manufacturer’s specifications. This helps to ensure the safety of everyone involved and prevents the potential for accidents or damage.
The NEC also requires that all electrical equipment be tested and labeled with the UL (Underwriters Laboratories) certification mark. This certification mark ensures that the equipment meets the highest safety standards, and is a sign of quality assurance.
