Safety requirements for electrical equipment for measurement, control, and laboratory use — Part 1: General
Canadian Electrical Code, Part III
Automatic — performing a function without the necessity of human intervention.
Balaclava (sock hood) — an arc-rated hood that protects the neck and head, except for the area of the eyes and nose.
Bare-hand work — a technique of performing work on energized electrical conductors or circuit parts, after the worker has been raised to the potential of the conductor or circuit part.
Barricade — a physical obstruction, e.g., tape, cones, or an A-frame-type wood or metal structure, intended to provide a warning about and to limit access to a hazardous area.
Barrier — a physical obstruction that is intended to prevent contact with equipment or energized electrical conductors and circuit parts or to prevent unauthorized access to a work area.
Battery — a system consisting of two or more electrochemical cells connected in series or parallel that is capable of storing the electric energy received, and returning such energy by reconversion.
Battery effect — a voltage that exists on the cell line after the power supply is disconnected.
Note: Electrolytic cells can exhibit characteristics similar to an electrical storage battery, and thus a hazardous voltage can exist after the power supply is disconnected from the cell line.
Battery enclosure — an enclosure containing batteries that is suitable for use in an area other than a battery room or an area restricted to authorized personnel.
Battery room — a room specifically intended for the installation of batteries that have no other protective enclosure.
Bonding (bonded) — a low-impedance path that is obtained by permanently joining all non-current-carrying metal parts to ensure electrical continuity and has the capacity to conduct safely any current likely to be imposed on it.
Bonding conductor — a conductor that connects the non-current-carrying parts of electrical equipment, raceways, or enclosures to the service equipment or system grounding conductor.
Boundary, arc flash — when an arc flash hazard exists, an approach limit at a distance from a prospective arc source within which a person could receive a second-degree burn if an electrical arc flash were to occur.
Note: A second-degree burn is possible by an exposure of unprotected skin to an electric arc flash above the incident-energy level of 5 J/cm 2 (1.2 cal/cm 2 ).
Boundary, limited approach — an approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists.
Note: See Clause 4.3.4 and Annex C.
