Hazardous Area Junction Boxes
Hazardous Area Junction Boxes
(OP)
Where an area is classified as Cl 1, Zone 2, do the junction boxes that have only terminals need to have a certification rating on the box?
Will the box be any different than a box in the same service in an unclassified area, except that perhaps the manufacturer may omit the label indicating that the box is certified for use in that area?
Any references or web URL's would be appreciated.
Any help, thanks in advance...

See 501.4(B)(4)in the National Electrical Code. In general junction or pull boxes in Class I, Division 2 areas are not required to be explosionproof.
