An electrical system is a network of electrical components and circuits that work together to provide power, control, and safety in a building or facility. Electrical systems include components such as wires, cables, transformers, switches, circuit breakers, fuses, and outlets. The system is designed to provide a reliable and safe source of electricity to power lights, appliances, machinery, and other electrical devices. The electrical system must be designed and installed in compliance with local building codes and safety regulations. The electrical system must also be properly maintained and regularly inspected to ensure that it continues to function safely and effectively. In commercial and industrial settings, electrical systems may be more complex and may require specialized expertise to design, install, and maintain.
