What is the main purpose of electrical bonding?

• A. To improve circuit efficiency
• B. To reduce the risk of electric shock
• C. To increase electrical resistance
• D. To enhance current flow

Answer: (B)

The main purpose of electrical bonding is to reduce the risk of electric shock. Bonding involves connecting various metal parts of an electrical system to ensure they are at the same electrical potential. By doing this, if a fault occurs, such as a short circuit or a ground fault, the voltage difference between these parts is minimized, lowering the risk of electric shock to individuals who may come into contact with them. This practice is critical for safety, as it helps to create a low-resistance pathway for fault currents to flow back to the ground, which activates protective devices like circuit breakers. When these devices trip, they help prevent prolonged exposure to dangerous voltage levels that could result in serious injuries or fatalities. Improving circuit efficiency and enhancing current flow are not the primary goals of bonding; rather, bonding is focused on safety rather than performance enhancements in the electrical system. Additionally, increasing electrical resistance is counterproductive in the context of bonding; the objective is to maintain a safe environment by ensuring components are well-connected and safe to touch, thus minimizing any dangerous potential differences.
