I am a BAS controls engineer, and am having issues finding any code requirements for type of NEMA enclosures needed. The spaces are marked as Class I Div 2, but at certain heights, do those requirements still uphold. Getting 18 NEMA 7 enclosures for Unit Heaters in the spaces will be quite costly and is not is budget. Are there places that I can look for more information regarding height requirements by NFPA/NEC. I have gone through Article 506 and have found nothing. There seems to be a lot of gray area. We will be supplying these enclosures with 120V, and stepdown transformer to 24 volts. Any information will me much appreciated. Thanks.
