GUA series conduit outlet boxes are installed within hazardous area conduit systems to:
protect conductors in threaded rigid conduit.
act as pull and splice boxes.
connect lengths of conduit.
change conduit direction.
provide access to conductors for maintenance and future system changes.
act as mounting outlets for fixtures (with appropriate covers).
act as sealing fittings (with appropriate covers).
Hub - 1/2" to 2".
Cover opening - 2" to 5" dia.
2. Terminator Cable Fittings
Terminator cable fittings are designed for use with
Type MC cable – corrugated aluminum, interlocked aluminum and interlocked steel
Terminator cable fittings are installed:
to provide a means for terminating type MC and
TC cable at junction boxes, control centers,
panelboards and enclosures for motor control and
electrical distribution equipment.
to form a mechanical watertight connection.
to provide ground continuity of cable armor.
indoors and outdoors in wet and dry locations.
in vertical and horizontal cable runs.
in non-hazardous and hazardous (classified)
locations. Both TMC and TMCX series can be used
in Class I and Class II, Division 2 locations. TMCX
series may be used in Division 1 locations and when
a seal is required.
TSC Epoxy Sealing Compound
A two part epoxy sealing compound is used
to seal TMCX cable fittings. It is quick and
easy to measure, mix and install. The
compound is kneaded until a uniform color is
obtained. It is then packed around the
conductors and cable armor to effectively
seal the cable.
3. GUB Junction Boxes
GUB series junction boxes are used in threaded rigid conduit systems in hazardous areas:
to function as a splice box, pull box or
equipment and device enclosure.
indoors and outdoors.
4. EJB Junction Boxes & EJB Custom-Built Control Panels
EJB junction boxes are used in threaded rigid conduit systems in hazardous areas:
as a junction or pull box.
to provide enclosures for splices and
branch circuit taps.
for housing terminal blocks, relays and
other electrical devices.
indoors or outdoors in damp, wet, dusty,
corrosive, hazardous locations.
where exposure to frequent or heavy rain,
water, spray, moisture, and humidity is
common; such as: offshore drilling facilities,
cooling towers, coal preparation and
handling facilities and sewage and waste
water treatment plant.
in areas which are hazardous due to the
presence of hydrogen or gases and vapors of
equivalent hazard such as found in process
industries, missile bases and gas
EJB custom-built control panels are used with EMP and EMPS barrel assemblies:
as a means of grouping control
stations for centralized process
control in hazardous areas in
to provide the necessary
pushbuttons, pilot lights, selector
switches, tumbler switches and
5. Unions and Elbows
UNY and UNF unions are installed in threaded thickwall conduit systems:
UNY – to connect conduit to a
conduit fitting, junction box or
UNF – to connect conduit to
conduit, or to provide a means
for future modification of the
UNA unions are used in conduit
and fitting installations when
entrance angle is between 90°
EL elbows are installed in
conduit run or in box or fitting
to change direction in threaded
rigid conduit run by 90°, or when
terminating at a box or fitting.
6. Reducers and Plugs
RE and REC reducers are used
in threaded heavy wall conduit
RE reduces conduit hubs to a
REA adapters enlarge drilled and
tapped openings by 1 NPT size.
REC connects two different sizes
of conduit together or is used to
replace a coupling and reducer
in an installation.
PLG plugs are used for closing
threaded conduit hubs.
EC couplings are used:
in hazardous areas where a
flexible member is required in a
conduit system to accomplish
difficult bends, or to allow for
movement or vibration of
connected equipment or units.
restrict the passage of gases,
vapors or flames from one
portion of the electrical
installation to another at
atmospheric pressure and
normal ambient temperatures.
limit explosions to the sealedoff
limit precompression or
‘‘pressure piling’’ in conduit
1/2" - 6".
Chico X fiber:
forms a dam between the integral bushing of the sealing fitting and the
end of the conduit and around the electrical conductors entering the hub
Chico A sealing compound:
forms a seal around each electrical conductor and between them and
inside of the sealing fitting to restrict the passage of gases, vapors or
flames through the sealing fitting at atmospheric pressure and at normal
Chico® SpeedSealTM Compound:
designed to separate and form an explosionproof seal around each
electrical conductor in Crouse-Hinds EYS and EYD sealing fittings.
restricts the passage of gasses, vapors or flames through the sealing fitting.
creates a seal for Class I, Division 1, Groups C & D and Class II, Division 1,
Groups E, F & G hazardous areas.
Chico A compound – 1 lb. to 5 lbs. (provides 23-115 cubic inches of
Chico X fiber – 2 oz. to 1 lb.
Chico A-P (5 pouches per carton) – provides 25 and 55 cubic inches of
Chico SpeedSeal - 2 oz. or 6 oz. cartridge
Drains and Breathers:
ECD drains and breathers are installed in
enclosures or conduit systems to:
–provide ventilation to minimize condensation
– drain accumulated condensate.
At least one breather should be used with
A breather is installed in top of enclosure or
upper section of conduit system.
A ‘‘standard’’ drain is installed in bottom of
enclosure or in lower section of conduit
‘‘Universal’’ breather or drain functions as a
breather when mounted at the top of an
enclosure, or as a drain when mounted in the
bottom of an enclosure.
‘‘Combination’’ breather and drain is used
in those applications where the use of a top
mounted breather is not practical due to
limited space; or in offshore and marine
installations where moisture may enter the
enclosure through the breather located on
top of enclosure.
Drains and breathers are installed in hubs
or drilled and tapped openings.
