• Lockout tagout hole in
cover gives users the
ability to lock the cover
closed while not-in-use
Protected Hinge:
Spring-Loaded Sliding Key Offers Increased
Safety:
• Rejects standard NEMA/EEMAC configuration plugs
that could cause an arc in a hazardous area.
• Also prevents the receptacle faceplate from being
rotated until the ENP plug is fully inserted.
• Cap design provides 360° of protection
around cover hinge to reduce damage from
dirt and corrosion
Integral Bushings:
Saddle Clamp

• NEC Article 501 and CEC Section 18
requires that metal frames or exposed
non-current-carrying metal parts of
portable devices used in hazardous
locations be grounded through an extra
conductor in the portable cord. ENR
Receptacles and ENP Plugs are
provided with an extra grounding pole.
CAUTION:
To reduce the risk of ignition of
hazardous atmospheres, do not use plugs
or receptacles in Class II, Group F
locations that contain electrically
conductive dusts.
Features:
•
Ark•Gard 2
receptacle incorporates
three spring-loaded slide keys that
prevent the receptacle face plate from
being rotated until the ENP plug is fully
inserted into the receptacle. To make
the connection, the ENP plug is fully
inserted, and the receptacle face moved
inward by pushing the plug forward. The
plug is then rotated, closing the circuit.
As rotation begins, the plug becomes
locked in the receptacle and cannot be
accidentally disengaged. In making or
breaking the circuit, any resulting
electrical arc is confined in the factory-
sealed chamber.
• Factory-sealed chamber encloses the
potential arcing components between
two explosionproof threaded joints.
These threads are specially coated to
guarantee freedom of movement, which
ensures on-off action. No additional
seals are required.
• One piece molded gasket seals cover
plate and ENP plug when plug is
inserted, providing full environmental
protection at the receptacle face.
• Top-hinged cover design with 45°
downward angle provides superior
protection in damp, wet, and dirty
locations.
• Field assembly is accomplished with
standard tools.
• Use standard EDS back boxes.
