Which Article addresses the installation of cranes and hoists?

The installation of cranes and hoists is primarily covered under Article 620 of the National Electrical Code (NEC). Article 620 outlines the requirements for the installation of electric hoists, cranes, and monorails, focusing on the safety and appropriate electrical connections to ensure safe operation in industrial and commercial environments.

Other articles mentioned relate to different aspects of electrical installations. For instance, Article 610 pertains to elevators and escalators, which while also concerned with lifting devices, does not specifically address the broader category of cranes and hoists. Article 555 focuses on marinas and boatyards, addressing electrical installations unique to that environment, and Article 590 discusses temporary installations, which is unrelated to the specific functions and requirements of cranes and hoists. Therefore, Article 620 is the relevant section for those installations, detailing the requirements necessary for ensuring safety and compliance in their electrical setups.
