Applications:
CPS receptacles, angle and straight types,
and CPP plugs are used:
• With portable electrically operated
devices such as motor-generator sets,
compressors, conveyors, portable tools,
lighting systems and similar equipment
• In locations which are hazardous due to
the presence of flammable vapors or
gases
• In damp or corrosive locations
• In petroleum refineries, chemical and
petrochemical plants, and other process
industry facilities where similar hazards
exist

Features:
• The delayed action feature permits the
plug to be used as an emergency pushpull switch
• CPS receptacles are equipped with a
rotating mechanism which prevents
complete withdrawal of the CPP plug in
one continuous movement. Details of
operation are illustrated and explained
below
Figure 1 shows a CPS angle type
receptacle assembly with CPP plug
fully engaged.
Figure 2 shows the plug withdrawn
until it is stopped by the delayed action
mechanism. In this position the circuit
has been broken and the arc has been
snuffed in the contact chambers.
To completely withdraw the plug as
shown in Figure 3, the delayed action
release lever must be rotated
counterclockwise. The time required to
actuate the mechanism permits
dissipation of the arc-generated heat
before contacts and arcing chambers
are opened to the atmosphere. When
inserting the plug, the reverse
procedure is followed.
• CPS receptacles are factory sealed to
simplify installation and wiring – external
seals are not required
• Series 152 receptacles have top hinged
cover design, with 45° downward angled
receptacle housing, to provide superior
environmental protection from
accumulations of dust, snow, ice, and
water
• Back boxes used for angle type
receptacles are standard EDS bodies.
Assemblies are listed with single and
two gang bodies and dead end or
through feed hubs –
• Back boxes used for straight type
receptacles are available with a variety of
hub arrangements in
• All receptacles and 30 ampere plugs are
provided with pressure terminals for
ease of field wiring. 20 ampere plugs
have solder terminals.

VAC
Grounding:
• NEC Article 501 and CEC Part 1 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
• CPS receptacles and CPP plugs are
provided with an extra grounding pole
• In plugs, provision is made for
attachment of the grounding wire to the
grounding pole. In addition, direct
connection is provided between plug
and receptacle housings and the
grounding pole. In the receptacle,
grounding is accomplished through the
conduit system
Interchangeability of Plugs
with Non-hazardous
Location Receptacles:
• 30 ampere CPP plugs can also be used
with standard 30 ampere AR Arktite
receptacles of the same style and
number of poles, thus permitting
portable devices suitable for use in
hazardous locations to be connected to
receptacles in both hazardous and nonhazardous areas
Note: Equipment to be used in hazardous areas must be
suitable for use in the specific hazardous location.
