Electrical equipment must comply with the Electrical Code because this code specifically establishes standards for the safe installation and maintenance of electrical systems and equipment. It governs aspects such as wiring methods, circuit protection, grounding, and equipment specifications to ensure that all electrical installations minimize hazards like electrical fires and shocks. This code is essential for ensuring that all electrical components meet safety and performance requirements relevant to their class of use, and is crucial for compliance with local regulations and policies.
