TMCX Terminator ™ II Cable Fitting
Installation & Maintenance Information
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE
APPLICATION
TMCX Series Terminator ™ II Cable Fittings are designed for use with Type MC/MC-HL jacketed metal-clad cable, interlocked armour and continuous corrugated
armour, TECK, ITC, and Type TC tray cable in hazardous (classified) locations when installed, in accordance with NEC/CEC. TMCX Series Terminator II Cable Fittings
are cULus Listed for hazardous locations (with TSC Epoxy Sealing Compound and Chico
Standard C22.2 No. 174. They are suitable for use in NEC/CEC Class I, Divisions 1 & 2, Groups A, B, C, D; Class II, Divisions 1 & 2, Groups E, F, G; and Class III,
when installed in accordance with NEC/CEC.
Explosionproof cable fittings should be installed, inspected, and maintained by qualified and competent personnel.
WARNING
To avoid risk of electrical shock, electrical power must be OFF before and
during installation and maintenance.

CABLE PREPARATION
1. Remove jacket (and armour, if applicable) from the cable to expose a
sufficient length of conductors required for the job.
For trade sizes 1/2" to 1-1/4" (M20 to M40) with type MC cable, leave
0.92" (23.3mm) of armour exposed when cable O.D. is from mid to upper
range, and 0.82" (21.0mm) when cable O.D. falls at the lower range.
Prepare cable. For Type MC, remove all fillers and shielding back to
armour. For Type TC, remove fillers back to cable jacket. Separate
uninsulated ground conductors back to armour or sheath to allow sealing
of individual strands.
2. Install TMCX into hub, wrench-tight.
3. Apply electrical tape to tip of conductors, and slide through integral dam
until armour or TC jacket contacts the dam.

4. Tighten back nut wrench-tight and visually inspect that environmental
seal has collapsed 360° around cable jacket. If desired, use included
torque table as a guideline.
CAUTION
To avoid risk of ignition:
1. Tools must not be allowed to damage the tapered flame path surfaces.
Do not handle sealing chambers roughly, or use tools that might damage
or scratch the tapered surfaces.
2. Any excess sealing compound should be removed from the exterior
tapered surface of the sealing chamber immediately.
3. The sealing chamber should be fully bottomed to the rear assembly
before assembly to the thread body.
4. Before reassembly, examine the tapered joint surfaces of the thread
body and sealing chamber. Surfaces must seat fully against each other
to provide a proper explosionproof joint. Remove any dirt or other
foreign matter from both surfaces. If either surface is scratched,
marred, corroded, or otherwise damaged, do not reassemble. Replace
the fitting.
5. After packing sealing chamber with TSC, be sure to allow compound to
harden before moving conductors.
5. Disassemble union nut and remove rear assembly from thread body.
5a. For Chico ® LiquidSeal installation: remove electrical tape and separate
conductors. Mix liquid compound per included instructions. Hold cable
gland upright and pour liquid compound until it reaches the top of the
compound chamber. Wiggle and separate conductors to make sure
compound settles between conductors, and top off if necessary. Maintain
assembly in vertical position until compound has gelled. See cure graph
for gel and energizing times.
IF 1647
5b. For TSC installation: (with cables containing more than four (4)
conductors, Chico ® LiquidSeal is recommended): unscrew and remove
sealing chamber, remove electrical tape, and separate conductors. Mix
two-part epoxy sealing compound provided by kneading and folding until
a uniform color is obtained (approximately 2-3 minutes). Pack a
sufficient amount of compound between and around conductors, using
the length and ID of the sealing chamber as a guide for shaping the
compound. Insert conductors into sealing chamber and slide the sealing
chamber down over the sealing compound. As compound is getting
compressed, use a hardwood stick or dowel to remove excess compound
and prevent it from getting into the mating threads. Screw sealing
chamber into mating thread and pack more sealing compound from the
top of the sealing chamber, making sure conductors are properly sealed
around, and the sealing chamber is completely full. Wipe off any
compound from the sealing chamber's exterior immediately. Allow
compound to sufficiently harden before moving conductors to avoid
creating voids. Allow TSC to cure for 24 hours before energizing
equipment.
