How does bonding differ from grounding according to NEC standards?

• A. Bonding connects parts to the earth while grounding connects metallic parts to each other
• B. Bonding connects metallic parts to each other to ensure electrical continuity; grounding connects parts to the earth
• C. Bonding is only applicable in residential settings; grounding is for commercial
• D. There is no difference; both terms can be used interchangeably

Answer: (B)

Bonding and grounding are two distinct concepts in electrical systems, primarily described by NEC standards. The correct response highlights that bonding involves connecting metallic parts to each other to ensure electrical continuity. This process facilitates the intentional connection of conductive elements to maintain a uniform electrical potential, preventing potential differences that could lead to shock hazards or equipment damage. Grounding, on the other hand, involves connecting parts of the electrical system to the earth. This connection serves multiple purposes, such as providing a reference point for voltage stabilization, protecting against lightning strikes, and diverting excess electrical energy safely into the ground. Understanding the separation of these two concepts is fundamental in wiring practices to guarantee safety and proper functioning of electrical systems. Bonding ensures that all conductive components are electrically connected to reduce shock hazards, while grounding provides a path for fault currents to flow safely into the earth.
