INSTALLATION INSTRUCTIONS
Spec Grade Non-Metallic FS/FD
30 Amp Circuit Interrupting Plugs
Important
Read and understand all instructions and
safety information before use. Be aware
of proper usage and potential hazards.
Part Numbers: 3750 and 3760 with suffixes; DP/__, PDG/__, and DPG/__
WARNING:
• Risk of shock, disconnect power before installation.
• Equipment connected to circuits having different
voltages, frequencies or types of current (AC or DC)
must not have interchangeable attachment plugs
per NEC Section 406.3(F).
Application:
Pin and sleeve contact design allows Spec Grade devices to be
tailored to specific industrial applications and special purpose work
in accordance with the National Electrical Code and local codes. The
devices can be rated and polarized for specific voltages and
amperages, preventing dangerous mismating of devices of different
ratings
Preparation:
1. Recommended tools
• Torque Wrench
• Screw drivers
• Wire strippers
• Ohmmeter
• Allen wrench 3/16"
2. Select cable size from table according to ampere rating of device.
Tab le
Ampere rating 30
Cable size AWG 10
Cord type S, SJ
3. Establish a wiring pattern so the same colored wire is put in the
same terminal on all plugs, receptacles and connectors in the
system. Spec Grade devices are polarized so the plug will enter
the receptacle or connector only one way.
4. Interior markings for wiring as follows
2p 3w
X/L1,Y/L2,G/
3p 4w
X/L1,Y/L2,Z/L3,G/
CAUTION:
• Product should be installed by a qualified electrician
in accordance with national and local electrical
codes.
• Use only copper or copper clad aluminum wire with
box mounted outlet or inlet. Use of other wire may
result in the connector failing in service.
Male plug installation
Instructions: (Figure on page 2)
1. Turn power OFF.
2. Strip cable jacket 1-2 inches as needed and conductors ½ inch
each.
3. Disassemble device removing gland nut #8, glide washer #7,
bushing #6, liner #5, collar nut #4 (furnished with plug only) and
interior #2 from housing #1.
4. Loosen screws #8B (2). Slide gland nut #8, glide washer #7,
bushing #6, (conical face towards device) liner #5, and collar nut
#4 over supply cable.
5. Loosen pressure screws #2A in pins. Insert stripped end of each
conductor in pin #2B or sleeve #2B in accordance w/wiring
pattern estab. in Step #3 under “preparation”.
6. Tighten pressure screws #2A to 20 in-lbs of torque.
a. For PDG/DPG styles: Attach RFI shield braid if required to
Aux. Ground strap #9 (if used) and tighten terminal screw to
5 in-lbs.
7. Reassemble interior #2 in housing #1 by lining up 2 tabs in
housing with 2 notches on interior.
NOTE: Plug interiors must be rotated to “seat” by grasping pins while
slowly turning housings. Interior must seat flat against housing inner
ring (liner #5 flush with housing #1).
NOTE: O-rings on plug interiors are lubricated at factory for sealing
and ease of assembly. If additional lubricant is required, apply a nonconductive lubricant such as GE type G661 silicone compound.
8. Slide liner #5 down cable, to seat on interior (in housing).
NOTE: Liner must be rotated by hand (note keyways) until properly
engaged. Liner #5 seats completely in housing #1, flush with back
end.

9. Position bushing (conical face down) into liner, with glide washer
ring on top. Secure in place with gland nut #8. Tighten gland nut
#8 on housing #1 to 40 inch pounds max or until bushing
compression firmly grips cable. Max. compression of bushing is
approx. 10% or to 90% of original I.D.. Other bushing sizes are
available. Gland nut #8 has an additional thread locking screw
#8A, tightened to 2 in-lbs, after clamps are assembled tight. See
Note*
General information
Electrical testing
Important: To avoid risk of shock or electrocution, or damage to
electrical equipment do not connect to power until the following
electrical tests have been performed.
1. Make continuity checks of wiring with ohmmeter to verify correct
phasing and grounding connections.
2. Check insulation resistance to be sure system does not have any
short circuits or unwanted grounds.
Connect all devices in the system, turn the power on and test the
system.
#4
Aux. ground strap (not shown)
#9
on PDG/DPG styles
NOTE: Make sure O-ring gasket #3 is on housing (for plugs only)
*NOTE: Hand assemble (item #8B) both cable clamp yokes, both
machine screws an nuts (supplied loose) onto cable gland #8 as
shown. Alternately tighten screws to firmly grip cable & bushing to
10-15 in-lbs. Use of automatic tools is NOT recommended unless
verified torque limit <15 in-lbs.
Maintenance
Inspection of electrical equipment used in industrial and heavy use
situations must be conducted regularly to ensure proper function
and safely.
Check for and correct the following items during inspection:
1. Unsecured contact wire terminals
2. Cracked or broken housings
3. An unfastened or loose ground conductor
4. Deteriorated or misplaced gaskets
5. Loose or missing screws
