Article 250 of the National Electrical Code (NEC) is titled "Grounding and Bonding." This article outlines the requirements for grounding and bonding of electrical systems and equipment to ensure safety from electrical shock and fires caused by electrical faults.
The main purpose of Article 250 is to provide a path for electrical current to flow safely to the ground in the event of a fault or overload, thereby preventing electrical shock or fires. The article outlines the requirements for grounding electrodes, grounding conductors, bonding jumpers, and equipment grounding conductors.
Article 250 also addresses grounding and bonding for specific types of electrical systems and equipment, such as separately derived systems, lightning protection systems, and grounding of non-current-carrying metallic parts of equipment.
It is important for electricians, electrical engineers, and other professionals involved in the design, installation, and maintenance of electrical systems to be familiar with the requirements of Article 250 to ensure that electrical systems are safe and meet the requirements of the NEC.
