These enclosures are Classified as to explosion and fire hazards only in according to Standard UL1203 4° ed.
The explosion-proof enclosures are suitable for Class I, Group B Hazardous Locations only when provided with from M20 to M90, 1/2 in. to 3 in., supply connection openings. If
other supply connection openings are provided, then the enclosures are suitable for Class I, Groups C & D Hazardous Locations only.
The 1/2 in. NPSM operator openings are only suitable for enclosures marked for Class I, Groups B, C & D Hazardous Locations
The enclosures covered by this Certification may have electrical components installed inside. The installation of electrical components shall not reduce the mechanical integrity of
the enclosures.
EJB UL
The enclosures may or may not be provided with hinges for service of the enclosures only.
PROTECTION AGAINST CORROSION
All ferrous-metal other than stainless steel shall be protected against corrosion, except at joint surfaces and conduit threads There shall be no materials

Internal Ground Screw – Hexagon head screw M6 x 10 with a stainless steel flat and lock washer provided on the base of the enclosure body.
External Ground – Terminal colored green, marked with the letter or word “G”, “GROUND”, or marked with a grounding symbol.
SUPPLY CONNECTIONS
NPT and Metric Supply Connections - The side walls of the enclosure are provided with conduit openings or none may be supplied, in which case field drilling and tapping
instructions are provided with each enclosure. The entry is drilled and tapped completely through the enclosure wall, and the inside edge is smoothed and well-rounded such that
the conductor insulation will not be damaged when installed. All unused openings are closed with plated steel, plated cast iron or aluminum close-up plugs which are threaded to
match the opening. Closer-up Plugs have to be Listed for the same Class, Group and Division as marked on Enclosure nameplate.
OPERATOR OPENINGS
The cover of the enclosure may be provided with operator openings in the cover only and located only as given in drilling and tapping instructions provided with each Classified enclosure. All unused
