designed to provide connection and distribution of secondary
electrical power (600 volts or less) between a power source and
portable or stationary electrical equipment. WSQ Series
receptacles are supplied in 2-wire, 3-pole and 3-wire, 4-pole

wiring.
2. Position receptacle facing downward and securely fasten
enclosure to the mounting surface and attach into conduit

the same electrical ratings and configurations. Refer to Cooper
Crouse-Hinds Product Catalog for a listing of compatible WSQ
Series dead front receptacles and matching ARKTITE plugs.
WSQ Series receptacles are dead front, where plug and
receptacle contacts cannot be made or broken under load. The
plug must be fully inserted in the receptacle and rotated
clockwise to manually operate the enclosed switch, closing the
circuit to the receptacle. The WSQ Series receptacle meets
OSHA lockout/tagout requirements.
WARNING
Before installing an WSQ Series receptacle, a wiring pattern
must be established for your system. Locations having different
voltages, frequencies or types of current (AC or DC) must not
have interchangeable attachment plugs per the National
Electrical Code. For each system the same colored wire must
be put into the same numbered contact on all plugs and
receptacles in that system. This will assure correct system
polarity and eliminate the possibility of equipment damage
and/or personal injury due to misphasing or shorts. Always test
before energizing.
The WSQ is suitable for use on circuits capable of delivering not
more than 10,000 amps (RMS symmetrical) 600V maximum
when protected by 40A (WSQ 30 amp) or 80A (WSQ 60 amp)
Class J fuses.
WSQ Series receptacles are polarized so plug enters receptacle
only one way. This provides for proper polarity of conductors
through plug and receptacle.
Note: Receptacles identified with the addition of Suffix S4 to
catalog number are supplied with receptacle contacts rotated 22-
1/2 degrees for special polarity application. They are compatible
only with plugs built with the same special feature.
Contacts in the receptacle insulating body are identified by
number. Corresponding plug contacts must always mate with
those in receptacle identified by the same contact number.
