What does NEC Article 250 cover?

NEC Article 250 specifically addresses grounding and bonding requirements within electrical installations. Grounding refers to the process of connecting parts of an electrical system to the earth to ensure safety and reduce the risk of electric shock. Bonding involves connecting different metal components together to ensure that they are at the same electrical potential, which helps to prevent electric shock and allows for proper operation of protective devices like circuit breakers.

Understanding Article 250 is crucial because it provides the guidelines necessary for creating a safe electrical system by ensuring that grounding is effectively implemented, which is essential for the protection of humans and equipment from electrical faults. This article also details the sizes and types of grounding conductors, the methods of establishing effective grounding systems, and the requirements for various installations to prevent electrical hazards.
