19、is the first edition of CSA Special Publication SPE-2000, Guide for Electrical Equipment for Installation and Use in Canada. This Special Publication is based on requirements of the Canadian Electrical Code, fart l (also referred to as CE Code, Part I) and is intended to be used as a guide for ident

20、ifying equipment requirements that are influenced by rules of the installation Code. Manufacturers need to be aware of requirements directly or indirectly linked to the CE Code, Part l when making choices in the design of electrical products intended to be installed and used in Canada. Electrical in

21、spection authorities base their official acceptance of electrical products upon Certification by an independent agency that the equipment conforms to applicable Standards consistent with maintaining the level of safety so as not to present an undue hazard to persons or property. The published applic

22、able Standards apply, except that additional features may need to be built into some products, or modifications made to existing products in order to meet installation Code requirements. This Guide addresses equipment related requirements that are based directly or indirectly (compatibility) on the

23、Rules of the CE Code, fati 1. Equipment related requirements based on other Canadian Codes which apply to electrical equipment installed in Canada have also been in cl uded. June 1994 Notes: (1) Although the intended primary application of this Guide for Electrical Equipment for Installation and Use

24、 in Canada is as stated above, it is important to note that it remains the responsibility of the user of the Guide to judge its suitability for any particular purpose. (2) The Guide for Electrical Equipment for Installation and Use in Canada is subject to periodic review, and suggestions for its imp

25、rovement will be entertained. (3) All enquiries regarding this Guide for Electrical Equipment for Installation and Use in Canada should be addressed to Canadian Standards Association, Standards Development, 178 Rexdale Boulevard, Rexdale, Ontario M9 W 1 R3.

26、3 b39 SPE-2000-94 Introduction This Guide for Electrical Equipment for Installation and Use in Canada is intended to be used in conjunction with the Canadian Electrical Code, Part l. The Guide covers certain construction requirements and features of electrical products that must be addressed when th

27、ose products are designed to meet international Standards and are offered for sale in Canada, where their installation and use is governed by Rules of the CE Code, Part l. Manufacturers who develop electrical products conforming to specific product Standards (National or International) need to know

28、how their products are affected by the installation Code. Effoits can then be directed toward making any necessary changes to products in order to gain acceptance by the local inspection authorities charged with enforcing Code rules and regulations aimed at achieving safe installation and usage of e

29、lectrical products. vi June 1994 CSA SPE-2000-94 * L750b 0522944 575 = Guide for Electrical EuuiDment for Installation and Use in Canada SPE-2000-94 Guide for Electrical Equipment for Installation and Use in Canada 1.

33、 and Il. 2. Definitions and Reference Publications 2.1 Definitions The following definitions apply in this Guide: Acceptable-acceptable to the authority enforcing the installation code. Alive or Iive-electrically connected to a source of voltage difference, or electrically charged so as to have a vo

34、ltage different from that of the earth. This term may be used in place of the term current-carrying, where the intent is clear, to avoid repetition of the longer term. Applicable standard-Standard of design, construction, testing, and marking that is (a) applied to electrical equipment by persons or

35、 associations who inspect, test, and report upon electrical equipment; and (b) intended to prevent exposure of persons and property to undue hazards. Attachment plug-a contact device for the readily detachable connection of a flexible cord or cable to receptacles, connectors, flanged equipment power

36、 outlets, and similar devices. Attachment plug, polarized-an attachment plug having blades so constructed or arranged that they can be inserted only in the intended position in a cord connector, current tap, flanged June 1994 I CSA SPE-12000-94 * = L750b 0522945 401 SPE-2000-94 equipment power outle

37、t, or receptacle. Authorized person-a qualified person who, by the nature of their duties or occupation, is obliged to approach or handle electrical equipment; or, a person who, having been warned of the hazards involved, has been instructed or authorized to do so by someone having authority to give

38、 the instruction or authorization. Circuit-a conductor or system of conductors and other electrical components through which an electric current is intended to flow. Class 2 circult-a circuit in which the power is limited in accordance with Rule 16-200 of the Canadian Electrical Code, Part 1. Conduc

39、tor-a wire or combination of wires not insulated from one another, bare or insulated, suitable for carrying an electric current from one piece of electrical equipment to another or to ground. Connector, wires device that connects two or more conductors together or one or more conductors to a termina

40、l point for the purpose of connecting electrical circuits. Continuous duty-a requirement of service that demands operation at a substantially constant load for an indefinitely long time. Control circuit-the circuit that carries the electric signals directing the performance of a control device, but

41、does not necessarily carry the power which the device controls. Cord-connected equipment-equipment that is connected to the electrical supply by a cord set or a power supply cord terminating in a suitable attachment plug.
