Applications:
• The EPC interlock receptacle is
designed for use as a service outlet for
portable equipment
• It is designed for use in damp, wet and
corrosive locations, indoors or outdoors,
in areas which are hazardous due to
flammable vapors, gases or combustible
dust. For example: refineries, chemical
plants, and other processing and
handling facilities of a hazardous nature
Features:
• Mechanical interlock mechanism for
dead front construction
• Receptacles are mechanically
interlocked with circuit breakers to
provide disconnect means, short circuit
protection and thermal time delay
overload protection
• A spring door receptacle, located at
bottom of 30, 60 and 100 ampere units
and at front of 200 ampere units, is
mechanically interlocked with the circuit
breaker operating mechanism for
maximum safety
• Plug and receptacle contacts cannot be
made or broken under load. The circuit
breaker cannot be closed until the plug
is fully inserted and the plug cannot be
withdrawn unless the breaker is open
• Operating handles can be padlocked in
either "ON" or "OFF" positions. Breakers
are trip-free of the handles and will open
under short circuit or overload even if
the handle is locked in the "ON" position
• Quick installation and leveling is
provided by the three-point mounting
arrangement which has one keyhole slot
at top and two open slots at bottom
• Bodies have four taper-tapped conduit
hubs with integral bushings. Two are
located at top and two directly below.
Sizes are as shown in the listings.
Grounding:
• EPC interlocked receptacles and
matching plugs are provided with an
extra grounding pole for attaching a
grounding wire. In addition, direct
connection is provided between plug
and receptacle and the grounding pole.
If a separate grounding wire is not
installed in the enclosure, grounding is
accomplished through the conduit
system.
Standard Materials:
• Bodies, covers and receptacle housings
– copper-free aluminum
• Operating handles – copper-free
aluminum
• Operating shafts – stainless steel
• Interior parts – sheet steel
• Insulation (receptacles and plugs) –
fiberglass-reinforced polyester
• Pressure contacts – brass
• Crimp/solder contacts – leaded red
brass
Standard Finishes:
• Copper-free aluminum – natural
• Stainless steel – natural
• Sheet steel – electrogalvanized with
chromate finish
• Brass – natural
• Fiberglass-reinforced polyester – natural
(red)
• Leaded red brass – electro-tin-plate

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.
†Pressure connectors are standard. Crimp/solder type terminators are optionally available for 2, 3 and 4-pole 30 ampere,
3 and 4-pole 60 and 100 ampere. For details, see page 1316. To specify, add the suffix "T" to the catalog number.
For example: APJ3365-T (Plug).

Interchangeability of Plugs with Other
Hazardous and Non-hazardous Location
Receptacles:
• Plugs listed for use with 30, 60 and 100 ampere EPC assemblies
are standard Arktite APJ/NPJ plugs. Other standard APJ and CPH
plugs of the same rating, style and number of poles may be used
with EPC receptacles, as well as with DBR, EBBR and EPCB
receptacles listed elsewhere in this section.
• As a result, portable equipment suitable for the location and
equipped with the proper plug can be used with AR/NR series
receptacles for non-hazardous locations: EBBR, EPC and EPCB
receptacles for Class I hazardous locations; DR and DBR
receptacles for Class II hazardous locations.

*Circuit breaker trip rating may exceed receptacle rating for welding equipment applications only,
as higher trip rating may not protect wiring.
††200 ampere units are suitable for Class I, Group D (NEMA 7D).
‡Enclosures with 600 volt circuit breakers from U.S.A. are available. Information on request.
†CSA Certified units are supplied with 600VAC FDB frame circuit breakers.
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.
