Applications
• Designed to supply power to portable or xed electrical equipment such as motor generator units, welders, pumps,
compressors, and similar apparatuses.
• Ideal for use on shipping docks, ports, and other “Ship-to-Shore” applications.
• Suitable for use in locations where a weatherproof enclosure is required.
• Interlocked receptacle design provides use in hazardous locations and rough environments.
Features
• Rugged and Type 4X watertight enclosure and cover, sealed with an O-ring.
• Grounding Style—Style 2 receptacle ground through shell and extra pole.
Receptacle is dead front without plug engaged.
• Arcing Conned—Interlock receptacle design means that all electrical switching
is done with an internal switch. The plug cannot be engaged or disengaged with
the receptacle when the switch is ON.
• Positive Contact—Brass contacts have integral springs for positive, maintained,
electrical contact.
• Receptacle face enables the engagement of plugs for a weatherproof union.
• Receptacle is designed so that it can only turn ON when the proper mating plug
is fully engaged and the padlocking collar is rotated. See Table 7 for a list of the
mating plugs.
• Receptacles come with both a ip cover and a screw cover for protection
against environmental conditions.
• Cover cannot be removed when the switch is ON.
• P4 Option—Special polarization prevents plug insertion into a receptacle wired
for a different voltage.
• Style 2 interlocked receptacles are equipped with contacts designed to provide
a safety polarization means called “controlled length” contacts. This feature will
not allow the plug grounding contact (Style 2) to touch an energized receptacle
“line” contact in the event the plug becomes damaged and/or loses its primary
polarization means and/or is rotated into the incorrect position.

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.
CAUTION
Before starting the installation, ensure the receptacle assembly is suitable for the intended location according to the National Electrical
Code or Canadian Electrical Code. If the receptacle assembly is not suitable, serious damage and injuries may result. Owners are
responsible for damages or injuries if these rules are not followed.
Prepare the Mounting Position
1. The receptacle assembly must be mounted on two 5/16 inch (for 30 A) or four 3/8 inch (for 60 A) steel, hex head bolts per ANSI
B18.6.3 and securely fastened to a wall, column, strut, or other vertical structure, in one plane, which is capable of supporting the
receptacle and its associated conduit and wiring.
NOTE: Bolts are not provided with the receptacle assembly.
2. Prepare the structure for mounting bolts by drilling, tapping, using securing nuts, or another method of providing thread anchors for
the bolts. See Figures 1 and 3 for the dimensions of the receptacle.
3. Install the bolts, leaving 1 inch under the heads. The bolts must be engaged at least ve full threads.
Mounting the Receptacle
WARNING
Before mounting the receptacle, ensure that the enclosed switch is in the “OFF” position.
1. Place the receptacle assembly on the previously prepared mounting bolts, with the receptacle ip cover at the lower-most position.
Make sure that the bolt shanks are in the mounting holes. Tighten the bolts to 10 to 15 ft.- lb. torque for 30 A or 18 to 20 ft.- lb. torque
for 60 A.
Opening the Receptacle Cover
WARNING
Ensure that the enclosed switch is in the “OFF” position.
1. Referring to Figures 2 and 4, turn the cover locking screw (Item #3) clockwise (inwards) until it enters into the groove of the receptacle housing body (Item #4). This prevents the enclosure cover (Item #2) from rotating and simultaneously locks the receptacle
interior rotation (also toggling of the switch).
2. Turn the enclosure cover counterclockwise (outward) to completely remove it from the enclosure.
3. After removal, we recommend that the enclosure cover be placed with the outer surface down, on a clean surface. Protect the
enclosure cover with a tarp or covering to ensure that it remains clean and functional.
Conduit Installation
CAUTION
For Group B locations, install sealing ttings within 4 inches (for 30 A) or 18 inches (for 60 A) of each conduit entry per the National
Electrical Code requirements. For Group C and D locations, install sealing ttings within 18 inches of each conduit entry per the
National Electrical Code requirements. Please note that both conduit entries must be used.
NOTE: Two 1 inch to 3/4 inch (for 30 A) or 1-1/2 inch to 1-1/4 inch (for 60 A) reducer bushings can be used to reduce the conduit entry
size to 3/4 inch (for 30 A) or 1-1/4 inch (for 60 A) if desired. The reducer bushings are not supplied with the receptacle.
1. Conduit entries are provided on both the top and bottom of the enclosure (see Figures 1 and 3).
2. Make sure all conduit entries are clean and free of debris before installing the conduit and close-up plugs.
3. On all conduits, reducer bushings, and close-up plugs, grease must be used to completely seal out water.
NOTE: We recommend applying Appleton thread lubricant (part number TLC-3) on threads in three generous lines, running parallel
to the thread axis and spaced equidistant around the thread.
4. Conduits and close-up plugs must be turned in until snug and then 1/2 turn further with a wrench. Make sure any installed
breathers and drains are tightened in the same manner.
NOTE: Do not over-tighten, as damage to the housing threads or any reducer bushings may occur.
5. At this point, ensure that all threaded holes in the housing are closed (including openings for breathers and drains) to prevent entry
of rain, splashed water, and hose directed water, and also to comply with Class I and Class II hazardous location requirements.

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:
1. Test to verify correct phasing and ground connections.
2. Test insulation resistance by meggering, high voltage, or hi-pot test, to ensure that the system does not have any short circuits or
unwanted grounds.
Clean the Receptacle Cover & Enclosure
Before replacing or closing the receptacle cover, it is strongly recommended that all dirt, debris, and other foreign materials be
removed from the enclosure interior. This action should be taken to help keep the breathers and drains from being plugged by these
materials.
1. Make sure the enclosure top face is clean. Wipe it with a clean, dry cloth to remove any foreign materials.
2. Clean the mating surface of the receptacle cover in the same manner, while being careful not to damage the O-ring.
Close the Receptacle Cover
1. Apply a thin lm of conductive grease (Appleton part number TLC-3 is recommended) on the threads of the housing. The purpose of
this grease is to further ensure against water migration through the receptacle cover and housing joint. Grease should be reapplied
each time the receptacle cover is opened.
2. Place/afx the cleaned receptacle cover in the enclosure by turning it clockwise. Ensure that more than seven threads are engaged
and that the cover sits face-to-face with the enclosure.
3. Referring to Figures 2 and 4, align the cover locking screw (Item #3) with one of the nearest holes on the cover ange.
4. Turn the cover locking screw counterclockwise (outward) all the way. This will lock the cover in place and will release the receptacle
interior so that the switch can be operated.
