What is the main purpose of load balancing in power distribution?

The main purpose of load balancing in power distribution is to evenly distribute electrical loads across circuits. By balancing the loads, the distribution system can optimize the use of available capacity, ensuring that no single circuit is overloaded while others are underutilized. This not only enhances the reliability and stability of the electrical supply but also minimizes the risk of overheating and potential failures in the system. Proper load balancing helps to maintain consistent voltage levels and reduces losses in the distribution system, leading to improved overall efficiency.

In contrast, increasing power voltage relates to aspects such as voltage regulation and transmission efficiency, while isolating faulty circuits pertains to safety and maintenance procedures. Decreasing electrical efficiency is contrary to the goals of a well-designed power distribution system, which aims to maximize efficiency and reliability.
