Electric Power Distribution in a Factory mainly operates on higher voltage ranges than the normal operating ranges in households. High voltages like 11KV, 33KV, 66KV, or 132KV from the generating stations are supplied through the main Grid to the respective industries or factories. They serve as an essential intermediary, ensuring stable and safe power supply, preventing damage to electrical equipment. The frequency of electricity must be stable, with limited fluctuations to avoid affecting product quality. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV. The distribution box (DB box) helps safely and efficiently distribute electrical power. Today, electrical systems are essential for homes and industries.

An electrical sub panel, also known as a sub distribution board or sub circuit breaker panel, is a smaller secondary panel connected to the main electrical panel in a building. It serves as an extension of the main electrical panel to distribute power to different areas or circuits. The process of connecting a secondary breaker box, known as a subpanel, to an existing main electrical panel allows for the expansion of electrical capacity in a specific area, such as a garage, basement, or workshop. A subpanel is essentially a satellite distribution point that feeds power to. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. Many feeders leave substation in a concrete ducts and are routed to a nearby pole. ) is a cabinet or cutout box which contains on controlling and protective devices (such as circuit breakers, fuses, switches etc. ) used to. Proper sub panel wiring is a fundamental skill for any licensed electrician, critical for safely expanding a building's electrical capacity.
