B. DISCONNECT SWITCH:
Disconnect switches occasionally fail and need to be replaced. The disconnect switch utilized in this receptacle can be
replaced with the same type and brand as factory installed. Doing so will not affect the U.L. Listing.
TO REPLACE DISCONNECT SWITCH:
•
Referring to "Figure A", loosen the line and load sides of disconnect switch pressure screws (13) and remove line side
wires (10) and load side wires (7) from switch (11).
•
Remove disconnect switch by removing disconnect switch mounting screws (12). Remember the orientation of the
handle (9) with respect to the switch position. The handle must indicate that the receptacle is "OFF" when the disconnect
switch is in the "OFF" position.
•
Replace the disconnect switch with the same type as shown in "Table F", reversing the steps taken to remove it. Make
sure to reconnect the wires to the same locations as before disassembly.
•
Torque the disconnect switch mounting screws (12) to 10-14 in-lbs to fasten switch to mounting brackets (14).
•
Torque the disconnect switch pressure screws (13) to 12-15 in-lbs to hold wires in place.
•
Conduct tests as detailed in section 6, page 6 of these instructions.
C. MOUNTING FEET (WITH ASSEMBLY NOT MOUNTED):
• Referring to "Figure G", remove mounting feet
screws from the back of the mounting feet assemblies (1).
• Replace mounting feet with new ones as shown in "Table G".
• Tighten mounting feet screws to 25-30 in-lbs torque.
D. COVER AND HOUSING HINGES (WITH RECEPTACLE COVER CLOSED):
• Referring to "Figure G", loosen and remove housing hinge bolts. Replace old hinge assemblies with the new
assemblies (2) as shown in "Table G". Make sure to properly align new hinge. Tighten all hinge screws to
25-32 in-lbs torque.

screws and remove wires (7) from lugs.
• Remove terminal block mounting screws and remove terminal block from housing.
• Replace the terminal block assembly (5) with a new one as speci
fi
ed in "Table G" by reversing the
steps taken to remove it.
• Torque terminal block mounting screws to 8-12 in-lbs to fasten to housing.
• Replace wires (7) into the same lug locations as removed from the old terminal block. Torque terminal block
lug screws to the value shown in "Table A", depending on wire size. Make sure wires are securely fas-
tened.
F. GROUND LUG:
• Referring to "Figure G" , loosen ground lug screw and remove ground wire from lug.
• Remove ground lug mounting screw from housing.
• Replace ground lug and mounting screw assembly (7) with the appropriate one shown in "Table G".
• Torque ground lug mounting screw to 16-20 in-lbs to fasten to housing.
• Reconnect ground wire to lug and tighten ground lug screw to 30-40 in-lbs torque.
