INSTALLATION INSTRUCTIONS FOR
“WSRD” INTERLOCKED RECEPTACLES
The WSRD receptacles are designed to accept clamping rings of the "ACP" plugs. Clamping rings fi t onto the
receptacle to provide a degree of protection against the
elements and to prevent plug fallout when the receptacle
is in the "OFF" position. When the plug is withdrawn from
the receptacle, the gasketed fl ip cover closes tightly against
the receptacle housing to provide weather-proof conditions
(NEMA TYPE 12 ). Screw cap is required for NEMA TYPE
4 applications.
INSTALLATION
1. PREPARE MOUNTING POSITION:
Owners are responsible for damages or injuries if these
rules are not followed.
WARNING
• Before starting with the installation, make sure the
WSRD interlocked receptacle is suitable for the intended location according to the National Electrical Code or
Canadian Electrical Code.
• If the interlocked receptacle is not suitable, serious
damage and injuries may result.
A. The WSRD interlocked receptacle must be mounted on
four (4) 1/4" maximum diameter steel bolts, securely fastened to wall, column, strut or other vertical structure, in one
plane, and must be capable of supporting the unit, as well
as its associated conduit and wiring.
NOTE: These bolts are not provided with the WSRD interlocked receptacle.
B. Referring to "FIGURE C" for dimensions of the WSRD
interlocked receptacle, prepare the structure for the mounting bolts by drilling, tapping, securing nuts or another method of providing threaded anchors for the bolts.
C. Install the two top bolts leaving 3/16" to 5/16" under the
heads.
• The bolts must be engaged at least fi ve (5) full threads.
2. MOUNTING THE WSRD INTERLOCKED
RECEPTACLE:
Place the interlocked receptacle on the previously prepared
mounting bolts, with the receptacle face
position ( See FIGURE C ). Make sure that the shanks of the
bolts are in the small part of the key-hole slot in the mounting
bracket. Install the two lower bolts. Tighten mounting bolts to
18-20 lb.-ft. torque to secure assembly in place.
3. OPENING ENCLOSURE COVER:
A. Referring to "FIGURE C", loosen the two (2) door
latches.
B. The cover

4. CONDUIT INSTALLATION:
A. Drill appropriate trade size hole in the top of the housing
according to the size of hub used. Drill this hole in the location
suggested in "FIGURE C".
B. Make sure hole is free of all burrs and sharp edges.
C. Install the corresponding hub in this hole according to the
instructions given with the hub kit.
D. At this point, ensure that all hubs are tightened appropriately.

6. ELECTRICAL TESTING:
All wiring must be checked and tested to ensure that all circuits
are according to plan and that there are no unwanted opens,
shorts or grounds. Do not apply power until the following
steps are completed:
A. Test to verify correct phasing and ground connections.
B. Test insulation resistance by meggering, high voltage or hi-
pot test, to be sure the system does not have any short circuits
or unwanted grounds.
331114-1 Rev. B 08/12/08 Page 5
7. CLEAN COVER AND HOUSING:
Before closing the cover ➂, it is strongly recommended that
all dirt, debris and other foreign materials be removed from
the interior.
• This action should be taken to help eliminate the possibility
of unwanted shorts or grounds.
• Make sure the cover gasket surface is clean and free of any
tears or damage.
• Clean the mating surface of the housing

9. POWER:
With all electrical tests successfully completed, the door
latched closed and the receptacle turned "OFF", power may
be applied to the WSRD unit.
10. OPERATION:
A. The WSRD interlocked receptacle can now be turned to
the "ON" position by lifting the operating handle
upper-most position.
Note that the WSRD interlocked receptacle cannot be
turned "ON" without a mating plug engaged.
• SAFETY FEATURE - The receptacle is interlocked to the
operating handle mechanism so that a mating plug cannot be
removed when the switch is in the "ON" position.

11. MAINTENANCE:
A. INSPECTION: Complete unit must be inspected regularly.
Schedule of inspections is determined by frequency of use
and environmental conditions.
• It is recommended that inspections be carried out at
least once a year.
WARNING
• If any part(s) of the "WSRD" unit or the mating plug
appear to be missing, broken or show signs of damage:
DISCONTINUE USE IMMEDIATELY!
This condition could cause serious or fatal personal injury
due to electrocution and/or equipment damage. Repair with
the proper replacement part(s) before continuing service.
DURING THE INSPECTIONS, PERFORM AT LEAST
THE FOLLOWING:

• Referring to "FIGURE C", loosen the line and load side lug
screws h of the disconnect switch and remove wires from
the switch. Take note of the orination of these wires for proper
reassembly. Also note that the wires i that connect the
recptacle to either the disconnect switcch directly (non-fused
version), or connect the receptacle to the fuse base (fused
version) are numbered according to the phase location (See
"FIGURE B").
• Remove disconnect switch and fuse base (if applicable)
mounting screws mountin screws
switch 12 and fuse base 13 (if applicable).
• Replace disconnect switch and fuse base, if applicable, with
the appropriate switch kit as shown in "TABLE E", reversing
