What is covered in Chapter 4 of the NEC?

Chapter 4 of the National Electrical Code (NEC) is dedicated to "Equipment for General Use." This chapter covers the requirements for various types of electrical equipment that are used in a wide range of applications. It provides guidelines and specifications that ensure the safe and correct use of general equipment, such as tools, appliances, and machinery, commonly found in residential, commercial, and industrial settings.

The focus on general use equipment emphasizes aspects such as installation, maintenance, and safety measures that must be adhered to in order to mitigate hazards and ensure optimal functionality. This distinguishes it from other chapters that deal with specialized conditions, equipment, and wiring methods, allowing users to reference Chapter 4 specifically when engaging with equipment that is designed for broad applications.
