Anyone know of any good Hazard. Location literature out there, besides NEC art. 500? Would like to know alot more about class I,II,III, but not having much luck finding anything.
NEC Handbook is more descriptive then NEC text. Also, many manufacturers have Classified detailed catalogs. (Crouse Hinds is one) Another source would be NFPA.
It is not supposed to be available until December 08, but when I worked in the chemical plant I had an NFPA standard pertaining to Hazardous Locations.
