I have come across a discrepency between the Handbook and the black code book. The local inspector and I were discussing this topic, a garage pit for large truck services. The client wants lights and outlets in the space. Inspector says that the pit is Class 1 Div 1 or would be div 2 if proper ventaliation is provided. However as I read this section in the handbook it clearly states that if the 1 CFM per Sq. Ft. is provided 12" from the floor of the pit, then the area shall be unclassified. Can you all help me understand if this is a true and accurate intrepretation?? If the pit is unclassified can standard fixtures, outlets, raceways, and boxes be installed in the pit??
Any help appreciated...
