Application:

ENR receptacles and ENP plugs are used:

ɀwith portable electrical equipment such as

compressors, tools, lighting systems, and

similar devices

ɀin areas made hazardous by the presence

of flammable vapors and gases or

combustible dusts

ɀwherever portable electrical equipment is

likely to be transferred from hazardous to

nonhazardous areas

ɀin damp and corrosive areas

ɀwhen power requirements do not exceed

20 amperes

ɀwhere general purpose application is

required

Features:

ArkȿGard 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

(Fig. 1). The plug is then rotated, (Fig. 2),

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.

ɀFactory-sealed chamber encloses the

potential arcing components between two

explosion-proof threaded joints. These

threads are specially coated to guarantee

freedom of movement, which ensures on-off

action. No additional seals are required.

ɀOne piece molded gasket seals cover plate

and ENP plug when plug is inserted,

providing full environmental protection at the

receptacle face.

ɀTop-hinged cover design with 45°

downward angle provides superior protection

in damp, wet, and dirty locations.

ɀMolded-in contact design provides superior

interior contact reliability.

ɀENP plugs can be used in nonhazardous

areas with standard U-ground NEMA/EEMAC

configuration 5 and 6 receptacles, eliminating

the need for two separately equipped

portable units of the same type. The ENR

receptacle will not accept standard NEMA/

EEMAC configuration plugs.

ɀENP plug handle body is designed with an

internal cord strain relief mechanism and a

cable sealing grommet which will accept

various cable diameters.

ɀField assembly is accomplished with

standard tools.

ɀUse standard EDS back boxes.

†Single gang receptacles purchased as a complete

assembly with EDS back box are suitable for Class I, Group

B usage. Two gang receptacles can be modified for Class I,

Group B usage. Add the letter B to Cat. No. Example:

ENRB22201. Seals must be installed within 11⁄2⍯of each

conduit opening. Receptacle units only (ie. ENR5201) are not

suitable for Class I, Group B.

Figure 1

Grounding:

ɀNEC 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.
