Several people in the inspection community have commented to me that they're running into an increasing number of non-compliant installations of these systems, and a seeming lack of awareness of installation companies regarding the requirements in the current edition (2016). There also seem to be challenges with cabinets that have listing marks on them despite never being tested according to NEMA 4 or 4X requirements.
Are you hearing about or experiencing these same challenges? If so, please describe them here. Then we at NFPA can figure out to how to best address them.
