Electrical codes are a set of regulations that govern the installation and maintenance of electrical systems. These codes ensure safety, efficiency, and reliability in electrical work, helping to prevent hazards such as electrical fires and shocks. They are developed by organizations like the National Fire Protection Association (NFPA) and are updated regularly to reflect new technologies and safety practices. Compliance with electrical codes is mandatory for electricians and contractors. These codes cover various aspects, including wiring methods, grounding, and circuit protection. Following these guidelines helps ensure that electrical installations meet safety standards and function properly, protecting both people and property.
