Ampacity - The current, in amperes, that a
conductor can carry continuously under the
conditions of use without exceeding its tem-
perature rating.
ANSI - American National Standards Institute.
Armor - A sheath, serving or braid or other
layer of metal applied over a cable to increase
its mechanical protection.
ASTM - American Society for Testing and
Materials.
AWG - American Wire Gage.
Bonding (Bonded) - The permanent joining of
metallic parts to form an electrically conductive
path that will ensure electrical continuity and
the capacity to conduct safely any current likely
to be imposed.
Breakaway Link - A device that is connected
in series with the pull rope that is designed to
break at a specified tension.
Cable - A cable is either an insulated conductor
(one conductor cable) or a combination of con-
ductors insulated from one another (multiple
conductor cable).
CEC – Canadian Electrical Code
Circular Mil (Cmil) - The area of a circle one
thousandth of an inch (or one mil) in diameter.
Compatible - A material suitable for use with
adjoining materials at the normal operating
and emergency environments (i.e., proper size;
similar materials, such that no adverse reac-
tion occurs; able to withstand the temperature
range, radiation, and other harmful parameters
for the area; as recommended for use by the
respective manufacturer).
Component - A segment of the cable, particu-
larly pairs, triads, etc.
Conductor - A wire or combination of wires not
insulated from one another, suitable for carrying
an electrical current.
Estimated Pulling Tension - The calculated
pulling tension based on conduit configuration
and cable construction.
Fire-Roc™ - RSCC trade name for a proprietary
insulation capable of passing the UL 2 hour fire
test as part of a qualified system.
Fitting - An accessory such as a locknut, bushing,
or other part of a wiring system that is intended
primarily to perform a mechanical rather than
an electrical function.
Galloping - A phenomenon that may occur
when pulling cables where the cable will slide,
based on the dynamic friction, then stop until
tension increases to a point as to overcome
the static friction. At this point, the cable slides
again, and the process repeats. To minimize
this effect use pulling ropes with minimal stretch
(i.e. aramid, etc.).
Ground Wire - The conductor leading from
a current consuming device to a ground
connection.
ICEA - Insulated Cable Engineers Association
(Formerly IPCEA).
IEEE - Institute of Electrical and Electronics
Engineers (Formerly two separate organiza-
tions: AIEE and IRE).
Insulation - As applied to electrical wire and
cable, insulation is the covering applied to
conductors in order to isolate and confine the
electrical currents which they carry. Insulation
materials are of many types, i.e., plastic,
rubber, etc. and are characterized by high
volume resistivity.
Jacket - An extruded plastic or elastomeric
material covering applied over an insulation or
an assembly of components to provide protec-
tion or act as a barrier.
Kcmil - A unit of conductor area in thousands
of circular mils (formerly MCM).
kV (Kilovolt) - One thousand volts.
LSZH - Low smoke zero halogen material
used as an optional jacket on RSCC VITALink
MC cable.
