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.
| Inspector's Authority [90.4] |

The National Electrical Code (NEC) covers the installation and removal of conductors and equipment for power, control and signaling, communication circuits, and optical fiber cables [90.2(A)]. The Code is intended to be suitable for legal adoption and enforcement by state or city legislation. The authority having jurisdiction (AHJ) is responsible for making interpretations of NEC rules, approving or not approving equipment, and granting special permission (written consent) for certain installations.
Keep in mind the AHJ cannot make up requirements and must cite the Code section if there is a violation. In rare scenarios the Code will sometimes require new products that are not available and, in this case, the AHJ may allow the use of a product that complied with the most previous edition of the NEC. An AHJ may accept methods that do not follow a specific Code rule provided equivalent safety is achieved, however this does not grant AHJ's the right to approve non-Code installations and most do not practice this provision unless its absolutely necessary.
