|The terms clarified below are used by the electrical trade and
are not normally found in the CEC or NEC.
Across-The-Line - Used to describe a full voltage motor controller.
Alu-Sheath - Used to identify an aluminum sheathed cable.
Antishort - The insulated bushing required when armoured cable is terminated.
Appliance - Portable units or groups of units assembled so as to form a complete unit.
Box Connector - Sometimes called a 300 V, 1010, 1030, or L16 connector.
Burndy® Connector - A term or trademark used to identify a split bolt type connector for splicing conductors.
Busduct - Used to identify a busway.
BX - Used to identify armoured cable.
Cab Tire - Used to identify flexible cords with the CSA letter
designation, beginning with the letter "S". Cab tire
usually has a condition of use of "hard usage" or "extra-hard
Chico - Used to identify the sealing compound used in explosion-proof seals.
Code Fuse - Used to identify a standard certified fuse.
Condulet - Used to identify fittings used with metal conduit such
as LB'S, LL'S, LR'S, E, etc.
Coreflex - Used to identify aluminum sheathed cable.
Device Box - Used to identify a box that holds
a device (eg, switch, receptacle, or cover) by means of 6/32 machine
- #1100 is a 3 x 2 x 1 1/2 in device box
- #1102 is a 3 x 2 x 2 in device box
- #1104 is a 3 x 2 x 2 1/2 in device box
- #1004 is a 3 x 2 x 3 in device box
Electro-Strip® - A trademark used to identify a multi-outlet assembly.
Enclosure - Used to identify a mechanical, electrical, and environmental protection for a control device, etc.
EYS - Used to identify an explosion-proof seal.
Fixture - Used to identify a permanently connected unit or group
of units assembled so as to form a complete unit that can be removed
or replaced without damaging any part of the building structure
(eg, luminaire, electric baseboard heater).
Grounded Conductor - Used to describe any conductor that is bonded to ground; often confused with neutral.
Harmonics - Used to describe electrical energy that is at a frequency other than 60 Hz, usually caused by unbalanced user loads.
Heater - Used to identify a thermal overload device.
Hickey - Used to identify:
(a) a manual bending device used to bend rigid
metal conduit; or
(b) a coupling used to connect a luminaire to its supporting device.
Neutral - Used to identify a conductor that is
always bonded to ground and intended to carry the unbalanced load;
a grounded conductor is not always a neutral conductor.
By definition, a neutral conductor
of a circuit requires at least three conductors in that circuit.
However, in the
trade, the term “neutral conductor” is commonly applied
to that conductor of a 2-wire circuit that is connected
to a conductor grounded at the supply end. Care should therefore
be used in the use of this term when applying Electrical
Nipple - Used to identify a short section of conduit used between
fittings, between fittings and enclosures, and between enclosures.
Nolox® - A trademark term used to identify the joint
compound used to prevent the oxide film from forming or reforming
on the termination or splice of stranded aluminum conductors.
Outlet Box - Used to identify a box that uses 8/32 machine screws
for attachment of fixtures (eg, luminaires, ceiling fans, covers,
plaster rings, extension rings).
- pancake 1/2 in deep round box
- octagonal 4 x 4 x 1 1/2 in deep
- square 4 x 4 x 1 1/2 in deep
- square 4 11/16 x 4 11/16 x 2 1/8 in deep
Panel - Used in place of panelboard.
Pot Light - Used to identify a recessed incandescent luminaire.
Pyro® - A trademark term used to identify mineral-insulated
Quadraplex - Used to identify neutral supported cable that has
three insulated conductors.
Rosette - Used to identify a device that is used for supporting
and connecting to the circuit the cord and sockets of flexible
Romex - Used to identify nonmetallic sheathed cable.
Running Board - Used to identify a piece of material at least
19mm thick used to protect conductors or cables from mechanical
injury (eg, in attic spaces).
Running Thread - Used to identify when the length of external
thread on a rigid conduit exceeds the maximum length stated by
Seal-Tight Flex - Used to identify liquid-tight flexible conduit.
Standard fuse - Another term for code fuse.
Starter - Used to identify a motor controller.
Stud - Used to identify a conduit run between a luminaire and
the fixture hickey (coupling) or the fixture hickey (coupling)
and the outlet box supporting the luminaire.
System - used within the context
of electrical power distribution, a system is intended to mean an electrical
installation in which the energy provided by that
installation to utilization equipment is derived from a single
energy source. For example, an electrical installation
supplied from a transformer or bank of transformers can be considered
a system; an installation supplied from a
different transformer would be considered a different system.
Tap Conductor - Used to identify a conductor that has an ampacity
rating less than the ampacity of the conductor or busbar feeding it.
Three-Wire Split Branch Circuit - Used to identify a multi-wire
Triplex - Used to describe a neutral supported cable that has
two insulated conductors.
Wire Connector - Identified by several terms or trademarks such
as marrette®, marr®, wire nut, and splice cap.
Wiremould® - A trademark term that is also commonly
used to identify a surface raceway.
