National Electrical Installation Standards

Standards as High as Your Own

Tuesday, November 14, 2023


Hi Charlie, several years ago I requested that the Code Committee consider GFCI protection for luminaries of jewelry display cases, I understand that since some of these display cases are florescent lighting, it can cause a technical problem. The Code Committee did not revise the code to require GFCI protection. I am curious as to why the Code Committee chose not to make the suggested revision. Do you know how someone can find out why a Code Committee made a decision on a specific suggested revision? I feel this one is especially important since on several occasions while working in these stores I witnessed infants being shocked when their mothers placed them on the showcases on rainy or snowy days. Thanks, Thomas Al Yasha


Hello Thomas, thank you for participating in the CQD, and thank you for your interest in electrical safety. We cannot speak directly to the results of your public input regarding GFCI protection of display cases. However, we can speak on where to find the Code Making Panel’s reasoning as to why a public input did or did not result in a code revision. The NEC® is subject to the revision requirements outlined by NFPA. These requirements are found in The Regulations Governing the Development of NFPA Standards. Sections and of the development regulations requires the Code Making Panels to provide a panel statement responding to each submitted public input. These Code Making Panel statements can be found in the 1st Draft and 2nd Draft reports of each edition of the NEC® online at
