Preface
This is the second edition of No. 117 of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes the first edition published in 1957.
This second edition includes revisions previously published and a number which have been approved but not published heretofore.
Since the adoption of this Standard in 1960 the variety in equipment in the room air conditioner category has emphasized the need to extend the original scope, to make more specific requirements for the enclosures, supply cords, switches, grounding, etc., and to amend the test requirements so as to reflect changes in practice recognized in other Standards. The changes will produce a more up-to-date Standard and remove some ambiguities which now exist, without requiring any changes to equipment which is now approved.
This Standard was prepared under the jurisdiction of the Committee on CE Code, Part II, which is subsidiary to the Committee on CE Code, Part I, and was formally approved by these Committees.
Scope

This Standard applies to cord-connected room air conditioners rated not more than 250 volts, single phase, with a rated capacity not over 36,000 Btu/hr, designed to be used in accordance with the Rules of Canadian Electrical Code, Part I.
1.2
This Standard applies to self-contained air-cooled window, or console or built-in-wall type room air conditioners, which have hermetic-type condensing units and which are intended to be installed in the conditioned room, usually in or in front of a window, or in a wall or transom.
