Installation & Maintenance Instructions for ECP/NCP Model “E”
U-Line® Plugs
RETAIN THIS INSTRUCTION SHEET FOR FUTURE REFERENCE. For safe installation and operation, please read these instructions
carefully and with full understanding.
Compliance & Ratings
UL 1203
Class I, Group B, C; Class II, Group F, G; Class III
Electrical Ratings
Maximum Voltage: 125 V or 250 V; Current: 15 A or 20 A; Configuration: 2W, 3P
Applications
• Locations where receptacles are used with stationary or portable electrically operated devices such as lighting systems, conveyors,
heaters, motor-generator sets, air conditioners compressors, and pumps.
• Locations where damp or corrosive conditions are encountered.
• Class I classied areas such as petrochemical plants, petroleum reneries, 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 our, grain, and starch
or any location where ignitable amounts of dust are present or amounts which would otherwise affect performances.
Installation
WARNINGS
• 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.
• Use cable diameters ranging from 0.538 to 0.639 inches. Failure to do so may result in overstressed wire terminations, which may
cause the conductors to pull out of the contacts and cause serious/fatal injuries due to electrocution.
• 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.
CAUTION
Before starting the installation, ensure the plug assembly is suitable for the intended location according to the National Electrical Code
or Canadian Electrical Code. If the plug assembly is not suitable, serious damage and injuries may result. Owners are responsible for
damages or injuries if these rules are not followed.
NOTICE
The plug should be wired with three-conductor, rubber-covered #12 AWG – #14 AWG Type SO or SOOW Cords with copper
conductors only.

Installing & Wiring
1. To disassemble the device, loosen (do not remove) the two front retaining screws from the plug and remove the plug base assembly
from the plug housing.
2. Remove plug base and insulator clamp from the plug housing. Note orientation of insulator clamp before complete removal.
3. Remove the four clamp screws from the insulator clamp.
4. Slide plug housing over cord. The self-sealing neoprene bushing will adjust to the cord diameter.
5. Strip the cable jacket and individual conductors as below:
FIGURE 2
6. Fasten the individual conductor wires to the proper terminals (in the plug base assembly) as follows:
For 125 V: GREEN wire to lug terminal “G”. For 250 V: GREEN wire to lug terminal “G”.
(terminal with grounding strap) (terminal with grounding strap)
WHITE wire to lug terminal with WHITE DOT. Other two wires to remaining lug terminals.
BLACK wire to remaining lug terminal.
FIGURE 3
Tighten the terminal screws to a torque of 15 in.-lb.
7. Slide insulator clamp down the cord and position over terminals. The insulator clamp has two slots which engage with the arc
barrier walls, providing proper orientation. Continue to slide the insulator clamp over the cord until it seats against the plug
base gasket.
FIGURE 4(
NOTE: Conguration of the plug housing is such that the plug base assembly and insulator clamp assembly can only be installed
in one position.
8. Place the cord clamp according to the cable diameter (0.538–0.639 inch) and tighten the four clamp screws to a torque of 15 in.-lb.
NOTE: DO NOT attempt to over-tighten the screws or bottom the clamp.
9. Slide the plug housing over the insulator clamp assembly and tighten the two retaining screws.
