What is the term for the permanent joining of motor frames, conduits, control boxes, and other metal parts not intended to carry current?

The term for the permanent joining of motor frames, conduits, control boxes, and other metal parts that are not intended to carry current is equipment bonding. This process ensures that all metallic parts of electrical equipment are electrically connected to each other to provide a low-resistance path for fault currents. By bonding these components together, it enhances safety by reducing the risk of electric shock, fire hazards, and other potential dangers associated with electrical faults.

Equipment bonding plays a crucial role in creating a safe operating environment, especially in industrial settings where machinery is widely used. It helps in stabilizing the voltage potentials between equipment and the ground, thus preventing electric shocks.

In contrast, grounding specifically refers to connecting the electrical system or equipment to a reference ground, which is a different safety measure aimed at protecting against electric shock and ensuring consistent electrical performance. Wiring pertains to the actual connections and conductors used to convey electric current, while insulation relates to materials that prevent electrical current from escaping the intended paths. Understanding these distinctions clarifies the significance of equipment bonding in electrical safety practices.
