CABINETS AND CUTOUT BOXES (CYIV)
[size=4]This category covers sheet-metal boxes and nonmetallic boxes. Cutout boxes are provided with a door secured by hinges and one or more fasteners and are intended for surface mounting. A cabinet consists of two parts: a cabinet box and a mating cabinet front that contains a door.
A cabinet may be flush mounted or surface mounted. These boxes are intended for installation in accordance with Article 312 of ANSI/NFPA 70, ‘‘National Electrical Code.’’
So a panel cover is not correct and although Deadfront is used the term here is the correct term, I must say.
PS: Anyone who wants me to review their electrical narratives can send them to me and let me BOLD the suggestions I have, so that when talking to a electrician the same language will be spoken.
