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 usage". 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 screws.
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 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.
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).
Panel - Used in place of panelboard. Pot Light - Used to identify a recessed incandescent luminaire. Pyro® - A trademark term used to identify mineral-insulated cable. 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 drop cords. 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 Code. 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 branch circuit. 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. |
