What does Article 250 of the NEC address?

Article 250 of the National Electrical Code (NEC) is dedicated to grounding and bonding requirements. This article outlines the fundamental principles and practices necessary to ensure that electrical systems are safely and effectively grounded. Proper grounding is crucial because it helps to protect both people and property from electrical faults, such as short circuits and lightning strikes.

The article provides specific guidelines for various types of systems, including residential, commercial, and industrial applications. It covers aspects such as grounding electrode systems, grounding conductors, and the bonding of various metal parts to ensure they are at the same electrical potential. This helps to minimize the risk of shock hazards and equipment damage. By ensuring that all conductive parts are properly bonded and grounded, Article 250 plays a vital role in enhancing electrical safety and system reliability in all installations.
