INSTALLATION AND

APPLICATIONS INSTRUCTION

Instruction Sheet for Appleton’s 20 Amp “CPP” Plug

Applications:

• Locations where receptacles are used with stationary
or portable electrically operated devices such as
lighting systems, conveyors, heaters, motor-generator
sets, air conditioner compressors and pumps.

• Locations where damp or corrosive conditions are
encountered.

• Class I –classified areas such as petrochemical
plants, petroleum refineries, paint and chemical plants
or any location where ignitable vapors or gases are
present.

• Class II –locations such as process industries where
there are dust hazards from handling such products
as flour, grain and starch or any location where
ignitable amounts of dust are present or amounts
which would otherwise effect performances.

Operational Data:

• Lift receptacle door and insert plug all the way into the
receptacle.

• Turn plug clockwise limit (37˚). This closes internal
contacts and completes circuit.

• Release plug.

• To remove plug, apply inward pressure on plug and
turn to counter-clockwise limit (37˚). Pull plug straight
out.

Features:

A. Heavy duty cable grip exceeds UL Standard 1010,

150 lb. pull-out test for classified locations.

B. Twisting plug locks it in place, cannot be accidentally

pulled out.

C. Special neoprene plug bushing accommodates

flexible cord ranging from .536 to .639 inch diameter.

D. Longer plug housing for better gripping and easier

plug insertion and withdrawal.

Instructions:

1. To disassemble device as shown, remove clinch ring
(1) from plug housing (2) interior.

2. Remove terminal block assembly (5) and insulator
clamp assembly (3) from plug housing (2).

3. Strip the cable jacket and individual conductors per
Table A.

Caution:

Care must be taken not to cut into the individual
conductor insulation when removing the outer cable
jacket and to not damage the conductors when
removing individual wire insulation.

Failure to do so will seriously degrade the electrical
properties of the cable and may produce
overheating/electrical hazard leading to
electrocution.

4. Slide plug housing (2) over cord (4).

• The self sealing neoprene bushing will adjust to cord
diameter.

5. Loosen four clamp screws (7) from insulator clamp
assembly (3).

Note:

The CPP Plug should be wired with three conductor
rubber covered #12 AWG through #14 AWG Type
SO Cords with copper conductors ONLY.

6. Slide insulator clamp assembly (3) over cord (4).

7. Separate front terminal block (9) from rear terminal
block (5). Fasten individual conductor wires to terminal
block assembly as follows:
For 125V: Green wire to grounding plug terminal “G”

(11).
White wire to lug terminal “W”.
Black wire to remaining lug terminal.

For 250V: Green wire to grounding plug terminal “G”

(11).

Other 2 wires to remaining 2 lug terminals.
Tighten terminal screw to a torque of 9 in.-lb.
Minimum/11 in.-lb. Maximum.

8. Slide insulator clamp (3) over cord (4) until it is seated
against the terminal block assembly.

9. Place the cord clamp (8) as shown in Ta b le B
according to cable diameter and tighten the four
clamp screws (7) to a torque of 10 in. -lb. Minimum/11
in.-lb. Maximum.

Caution:

DO NOT attempt to over-tighten the screws or
bottom the clamp.

10. Slide plug housing (2) over insulator clamp
assembly (3) and terminal block assembly. Rotate
housing to find correct orientation

11. Insert clinch ring into plug housing interior.

Warning:

Use cable with diameters within the specified range
given in Table B.
Failure to do so may result in over stressed wore
terminations which could cause the conductors to
pull out of the contacts and cause serious/fatal
injuries due to electrocution.

Caution:

Plug and cord connections are rated for use with
Type SO cord with copper conductors ONLY.

Maintenance:

Electrical and mechanical inspection of all components

must be performed regularly. It is recommended that
inspection be performed a minimum of once a year.

Warning:

• Electrical power must be turned “OFF” before and
during installation and maintenance.

• Failure to do so may result in serious or fatal
injuries due to electrocution.

Warning:

If any parts of the plug, receptacle or cable
connector appear to be missing, broken or show
signs of damage:

DISCONTINUE USE IMMEDIATELY

This condition could cause serious/fatal personal
due to electrocution and or equipment damage.
Repair with proper replacement part(s) before
continuing use.

1. Inspect all contact wire terminals for tightness.

• Discoloration due to excessive heat is an indicator of
possible problems and should be thoroughly
investigated and repaired if necessary.

2. Check grounding and bonding for correct installation
and secure connection. (Retorque).

3. Check gaskets for deterioration and replace if
necessary.

4. Clean exterior surfaces making sure nameplates
remain legible.

5. Inspect cable grip tightness to ensure proper
cord/cable gripping.

6. Torque all screws as described in instructions before
using device.

7. Inspect all parts and replace those which are broken
or excessively worn.

8. Check contacts for signs of excessive arcing or
burning and replace if necessary.

In addition to these required maintenance
procedures, we recommend an Electrical Preventive
Maintenance program as described in the Nation
Fire Protection association Bulletin NFPA No. 70B.

Electrical Testing:

Do not connect to power until conducting the following

electrical tests:

• Test continuity of wiring to verify correct phasing and
grounding connections.

• Measure insulation resistance to be sure system
does not have any short circuits or unwanted grounds.

Electrical Ratings:

125-250V A.C., 20A at 2 H.P.; 28V D.C.

Warning:

• Do not modify these devices in any way.

• Replace any missing or broken parts with proper
replacement parts from Appleton Electric, LLC.

• Modifications of these devices or substitution of
parts with non-standard parts may result in
serious/fatal personal injury from electrocution.
