Twist-Lock® Devices
20 and 30 Ampere Plugs and Connector Bodies
Features and Benefits
Our 20 and 30 amp Insulgrip® plugs and connectors
maintain Hubbell’s classic integrity, solid construction
and safety features that make these devices the ‘industry
standard’.
Insulgrip’s cord gripping design clamps the conductors, not
just the cable jacket, making it the industry’s most powerful
cord grip. The restyled cord grips provide a clean, one-piece
look, and actually make it stronger.
Insulgrip’s design guards against contamination.
The nylon body and housing of the plugs and connectors
are resistant to industrial chemicals, solvents and
hydrocarbons. The face of each plug is molded specific
to the blade configuration, eliminating holes that attract
debris. And finally, our dust shield provides additional
protection from contamination.
Additional features that make Insulgrip the industry standard
are our improved contacts that provide better terminations,
an exclusive double rivet design for the female contacts and
an easy to read identification system.
The Hubbell Twist-Lock® line of plugs and connectors
remain the broadest in the industry. Hubbell has you
covered – proven performance, innovation and selection.
Tough ribbed nylon housing
for secure gripping
Self-threading screws
specially designed for
secure assembly
Insulated nylon construction to
keep non-current carrying parts
from becoming energized
Wiring chambers separate and
positively insulate conductors
and promote easy inspection
Funneled holes to permit “straight-
in” conductor insertion
Improved terminations include
#10 multiple drive screws and
thicker .080" clamping nuts
Two-part cord grip tightens with
two screws for maximum retention
force. Broad gripping area to
accommodate wide range of
cable diameters
Integral dust shield protects
wiring chamber from dust or
contaminants. Single-piece
shield/housing eliminates need
for separate step at installation
Product identification is visible while
device is in use. Markings include
catalog number and ratings printed in
the IEC color scheme on the current-
carrying portion of the device

Twist-Lock® Devices
The Standard for Locking Receptacles
Features and Benefits
Twist-Lock® receptacles combine functional design features,
unparalleled quality to deliver pace-setting performance.
The high-impact nylon face of each Hubbell Twist-Lock
receptacle has a colored ring. Keyed to an internationally
recognized color coding scheme, this ring enables mating
devices to be matched quickly. It's just one more example
of user-oriented thinking at Hubbell.
The terminals in each Hubbell Twist-Lock receptacle are
mechanically and electrically the finest available. These
terminals incorporate unique design features to contain
and hold conductors, including an external back wiring
“wraparound” clamp, a wire restraint recess and more.
The materials used in every receptacle are of the highest
quality. The all brass mounting system provides a safer,
lower resistance ground path than those made of steel.
The thick wall base is constructed of an engineered
thermoplastic to offer the benefits of a thermoset, yet with
much greater impact resistance.
Hubbell Twist-Lock Receptacles: Voltage color coding on
the outside. Proven designs and quality materials on the
inside. Any way you look at them, they are the standard
of the industry.
125V 250V 277V AC 480V AC 600V AC 125/250V
Glass-Reinforced thermoplastic
polyester base (RTP) has the
desirable characteristics of a
thermoset material, including
heat, flame resistance and
dimensional stability. The
impact resistance it provides,
however, is much greater than
that of a thermoset
One-piece contact with long
spring arm (low stress) and oxide
cutting nibs: prevents stress and
overheating associated with riveted
contact and short spring arms
#10 silicon bronze terminal screw provides
greater strength and resistance to corrosion
and stripping. Anti-rotational clamp has a
stop to limit the amount of cocking when
only one side is used. Accommodates both
back and side wiring
Wire restraint recess
for both back and side
wiring, greatly reduces the
possibility of loosening
the terminal connection
High-impact, abuse-resistant
nylon face
Face color coding by voltage facilitates
locating and mating of proper devices
Boss diameter is 1.562"
on 20 and 30A devices for
simplifying installation and
accessory selection
All-brass mounting and grounding
system provides a lower resistance
ground path and greater resistance to
corrosion than steel mounting systems

Switched Safety Enclosures
Switched Twist-Lock® and Hubbellock® Enclosures
The Switched Twist-Lock® and Hubbellock® Enclosures
integrate a receptacle and a switch to produce distinct
advantages for the user. This enclosure replaces box,
switch, cover and all in a compact design that meets
Type 3R Rainproof or 12K Dust-tight requirements.
The receptacle is angled downward for a low profile, and
it maintains a low profile while accommodating either a
20 or 30 Amp Twist-Lock receptacle or 30 Amp, 4 wire
Hubbellock receptacle. The enclosure can be used in top,
bottom or back feed applications. The handle is designed
to be locked in the off position for lockout protection.
Hubbell has developed the Switched Safety Enclosure
because users want to be able to disconnect higher voltage
devices confidently. Hubbell responded with a line of
Switched Safety Enclosures for Twist-Lock and Hubbellock
receptacles.
The provision of the integral switch and the receptacle in
a compact, non-metallic enclosure encourages the safe
operating practice of disconnecting at the switch rather
than the plug and receptacle.
For plants and factories in a wide variety of industries,
as well as light industrial facilities, Hubbell’s Switched
Enclosures offer an upgrade that’s convenient, compact
and easy to install.
Lockable handle provides
lockout protection for greater
safety and complies with
OSHA lockout requirements
Premolded conduit entry hole is
offset to prevent water condensation
from falling directly on interior
electrical components, while
speeding installation by making it
easier to pull conductors
Heavy-duty internal frame bonds

DIN rail to accommodate the switch
Angled 20 or 30 amp Hubbell Twist-Lock®

Mechanical Interlock Switched Safety Enclosures
Circuit-Lock® Unfused Safety-Shroud® Twist-Lock®
Hubbell offers the only mechanical interlock for
Twist-Lock®. This new, unfused mechanical interlock
for watertight Safety-Shroud® Twist-Lock® integrates a
watertight receptacle with a linked disconnect switch to
provide a mechanically interlocked receptacle. This virtually
eliminates the possibility of making or breaking the circuit
while under load or making a casual or “lazy” connection.
The switch cannot be turned “ON” until the plug is properly
inserted and locked, and the plug cannot be removed until
the switch is turned “OFF.” All these protective features are
included in a compact Type 4X hose-directed water and
corrosion resistant enclosure that allows for top, bottom or
back feed options.
The non-metallic enclosure is nonconductive, yet has an
internal frame to assure ground continuity with metallic
conduit.
In addition, this interlock works with all Safety-Shroud
Twist-Lock Plugs. The new unfused mechanical interlock
for watertight Safety-Shroud Twist-Lock can be locked
out as a method of compliance with OSHA lockout/tagout
regulations.
Lockable handle provides
lockout protection for greater
safety and complies with
OSHA lockout requirements

Variload Twist-Lock® Devices
In many large plants and laboratories the number of circuits of different ratings and
frequency is greater than the number of blade configurations available in conventional
wiring devices.
Prior to NEMA configuration standardization the solution was “Variload Twist-Lock”
devices with four non-interchangeable center pin and slot configurations that can be
designated to different circuits.

Hubbell’s 50 amp Twist-Lock® devices features heavy-duty
design built for heavy-duty applications. These Hubbell
50 amp Twist-Lock plugs and connector bodies are built
to go where you need power, even in some of the
harshest environments.
On the outside, 50 amp plugs and connectors are made
of Super tough nylon for better impact resistance. On the
plug, the stainless steel shroud not only provides protection
and durability, but safety as well. That’s because the rigid
construction restricts distortion, thus minimizing the
possibility of mating incorrect devices.
On the inside are the kinds of features that separate Hubbell
from all the rest. The cord grip has been designed with
offset gripping jaws to securely hold the conductors – not
just the cord jacket. Hubbell’s box terminals speed wiring
and provide a superior termination. The plug’s thermoplastic
polyester interior provides excellent heat resistance without
compromising strength.
In all, it’s the combination of function and performance that
Hubbell demands of all its products. And it’s why we’ll never
add a feature that compromises performance.

Features and Benefits
Note: Above cut-away view and call-outs are construction elements pertaining specifically to the 30A Hubbellock series.
While the Hubbellock contact interface design applies to all, there are construction elements that are different, depending on the amperage.
Three-piece thermoplastic clamp assembly
with fast-lead stainless screws provides a
more consistent durable grip. Grommets
provide a sealed cable entry that protects
against the entry of moisture and dust
Superior wire terminations are assured
with box terminals and screws with
pressure pads. This design captures stray
wire strands and permits more clamping
pressure on the wire without damaging it.
Loosening of terminations and resulting
heat build-up are greatly reduced
Impact resistance in the interior of the
female device comes from a strong
thermoplastic material
No “lazy” connections because a spring-
loaded safety shutter automatically ejects
the plug if it hasn’t been properly locked
into the female device. This eliminates
teasing of the contacts, a major cause
of contact burn-up
Arcs are snuffed out, when devices
are mated or unmated under load, by
spring-loaded safety shutter
Longer contact life is assured by
supplementary springs. Other
devices rely just on contacts
themselves to provide proper
contact pressure Enhanced safety because access to
live female contacts is restricted by the
spring-loaded safety shutter
Positive locking is ensured by the nose
of the plug being keyed into
a detent in female device. This lock is
independent of the contacts or
a separate mechanical lock
Insulated non-metallic housing
enhances safety and abuse
resistance
