A distribution panel is an essential component of an electrical supply system, designed to divide incoming electrical power into multiple subsidiary circuits. It houses protective devices such as fuses or circuit breakers for each circuit, all enclosed within a single panel. These systems typically include a main switch and residual current breakers with overcurrent protection to ensure operational safety.

Distribution panels are widely used across industries, especially in environments that involve heavy machinery. Their primary function is not only to ensure the efficient distribution of electrical power but also to protect connected circuits from overloads and short circuits.
