What is the main purpose of bonding in electrical systems?

The main purpose of bonding in electrical systems is to connect systems together for equal charge distribution. Bonding ensures that all conductive parts of an electrical system are linked, allowing for the equalization of voltage between them and reducing the risk of electric shock. By connecting various metallic parts of an electrical system, bonding helps maintain a safe and consistent electrical potential, which is crucial in preventing differences in voltage that can lead to dangerous electrical discharges.

While grounding, which is sometimes confused with bonding, primarily aims to connect the electrical system to the earth, bonding focuses on the internal connections within the system. This distinction is essential, as grounding and bonding serve complementary but different roles in maintaining electrical safety. Overcurrent protection pertains to devices like fuses and circuit breakers that prevent excessive current from causing damage, and reducing electrical interference relates more to shielding and filtering techniques rather than the purpose of bonding itself.
