In the National Electrical Code, Article 600 is primarily concerned with which type of installation?

Article 600 of the National Electrical Code specifically addresses the installation requirements for electric signs and outline lighting. This section is crucial as it provides guidelines on the safe installation and operation of these types of electrical equipment, which often operate in public spaces and require adherence to strict safety standards to prevent hazards such as electrical shock or fire.

The provisions in this article include requirements for circuit installation, grounding, and specified distances that must be maintained from other structures or systems, ensuring that electric signs and outline lighting are not only visually appealing but also safe for installation and use.

In contrast, the other options focus on different categories: office furnishings have their own occupancy requirements that do not pertain specifically to electrical installations outlined in Article 600; cranes and hoists are covered under a different set of articles more related to industrial equipment; and elevators and escalators also have their dedicated sections that cover safety and operational guidelines distinct from those applicable to electric signs and lighting. Thus, Article 600’s primary focus on electric signs and outline lighting is distinctive and well-defined.
