Keeping up with the requirements of the Code should be the goal of
everyone involved in electrical safety. The following is what I feel is an
important rule in the 2020 NEC®, complete with
graphics and a video. I encourage you to use it as a training resource for
your organization, and share it with your colleagues.
| Bonding, Other Enclosures [250.96] |

When it comes to making the use of electricity safer, nothing can compete with the bonding requirements of the NEC. Remember that bonding is the connection(s) made to ensure the continuity of all noncurrent-carrying metal components of an electrical system.
But what exactly is meant by other enclosures? Well other enclosures are, metal raceways, cable trays, cable armor, cable sheath, enclosures, frames, fittings, and other metal non–current-carrying parts that are to serve as equipment grounding conductors or part of an effective ground-fault current path. Any nonconductive paint on equipment must be removed to ensure electrical continuity and the capacity to conduct safely any fault current likely imposed. This rule has to do with the performance requirements of grounding and bonding, for example if a non-metallic raceway is installed with metallic boxes then 250.96(A) requires us to bond the metal box.
So why is bonding so important and how does it make using electricity safer? Read the attached PDF, study the graphic, and watch this informative video as myself and a panel of experts explain.
