Installation & Maintenance Information
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
APPLICATION
AR Series ARKTITE Heavy Duty Cable Connectors are
designed to provide connection and distribution of
secondary electrical power from a power source to portable
or stationary electrical equipment. APR Series Cable
Connectors are compatible with AP Series Plugs. Crouse-
Hinds Product Catalog provides a complete listing of
compatible ARKTITE heavy duty plugs. APR Series Cable
Connectors are supplied in 3 and 4 pole designs. They are
capable of carrying a maximum continuous current of 200
or 400 amperes at a rated voltage of 600 volts AC from 50
through 400 Hertz, or 250 volts DC. 200A rated APR
Series Cable Connectors feature load breaking capability in
emergency situations at or below the cable connectors
maximum current rating. Self-closing spring doors provide
environmental sealing.
NOTE: Crouse-Hinds 200 and 400 amp cable connectors
are intended for use with portable power cable or flexible
state & lighting power cable as described in the National
Electrical Code®, Article 400.
CAUTION
400A rated APR Series Cable Connectors may only be
connected or disconnected with electrical power OFF.
Two styles of cable connector grounding are available.
Style 1 units have the grounding conductor connected to
the cable connector housing with a pressure connector

Before assembling an APR Series Cable Connector, a
wiring pattern must be established. The same colored

assure and correct system polarity and reduces the
possibility of equipment damage and/or personal injury
due to misphasing or shorts.
Page 1 IF 854 • 04/12
ARKTITE plugs and cable connectors are polarized so plug
enters cable connectors only one way. Contact recesses in
insulating bodies are identified by number. This assures
proper polarity of conductors through plug and cable
connector.
To ensure uniformity of the system follow these instructions
or use your own established standards. Electrical
continuity testing is required to verify proper polarization.
Connect wires, identified by color in first column of Table 1, to
contacts identified by number noted in columns to the right.
White wire is connected to contact connected by #2. Connect
other contacts in accordance with color wires.
Conductors are identified by the color of insulation on each

of 250-45 of the NEC. If conductors are not identified with
exactly these colors, these colors may be assumed in
making proper connections.
If the conductors are all alike except one, that one is to be
assumed to be white and the others to be in the same relative
locations at the other end of same cable. If any doubt exists
on color identification, test them out electrically.

through plug and receptacle connections to conduit or some
other non-current-carrying conductor permanently grounded in

the cable connector is compatible with the APR Series
Cable Connector strain relief and bushing. Refer to Tables 2
