Definitions 2.1 The f
13、ollowing definitions apply in this Standard: Bonding a low impedance path obtained by permanently joining all non-current-carrying metal parts to assure electrical continuity and have the capacity to conduct safely any current likely to be imposed on it. Bonding conductor a conductor that connects t
14、he non-current-carrying parts of electrical equipment, raceways, or enclosures to the system grounding conductor. Collar ferrule the portion of a standard housing to be used solely as a mounting means inside a sign enclosure. Pendent type receptacle a receptacle housing intended to be mounted to the
15、 end of the gas tube without any other direct support. 3. General Requirements 3.1 General requirements applicable in this Standard are given in CSA Standard C22.2 No. 0. 3.2 Reference Publications 3.2.1 Where reference is made to CSA Standards of the CE Code, Parts I and II, such references shall b
