Navigating the grounding and bonding of electrical systems can be a tall task unless you have taken the time to familiarize yourself with the requirements of Article 250 of NFPA 70 ®, National Electrical Code ® (NEC ®). Where should you start? The following are some common questions from individuals who are just beginning to explore Article 250.
Grounding and Bonding Performance Requirements, based on the 2023 NEC
As you bond metallic objects together, you are building part of the EGC. Given its construction requirements and its primary function, the EGC serves more the purpose of bonding than grounding . However, it does ultimately connect to the grounding point at the service or separately derived system.
Question: Explain the difference between grounding and bonding , and describe the role of the Main Bonding Jumper. Model Answer: Grounding is the intentional connection of an electrical system or equipment to the earth through a grounding electrode, establishing a reference voltage and providing protection against lightning and line surges.
250.8(A) Permitted Methods of Grounding and Bonding.
In the 2023 NEC®, the parent text of 250.8 (A) referenced the connection method for joining equipment grounding conductors, grounding electrode conductors, and bonding jumpers, but did not expressly mention the actual termination points from those connection methods to the equipment. This omission created a subtle but important gap.
