What defines a "locknut" in electrical components?

A locknut is primarily characterized as an accessory performing a mechanical function, specifically used in electrical installations to secure and lock conduit fittings to boxes or enclosures. This mechanical function is essential because it ensures that the connections remain tight and prevents loosening over time due to vibrations or environmental factors.

In electrical work, locknuts are often employed to provide a secure method of fastening, thereby improving the integrity of the installation. While locknuts may contribute to the overall safety and functionality of the electrical system, their primary role is mechanical—ensuring components stay in place rather than serving as a protective casing, connector, or fastening device for wires themselves.

Understanding the specific definition of a locknut helps differentiate it from other electrical components and clarifies its purpose in maintaining the stability and reliability of electrical connections.
