Preface This is the third edition of CSA C22.2 No. 206, Lighting poles, part of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes the previous editions, published in 2013 and 1987. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0, General Requirements - Canadian Electrical Code, Part II. Significant changes to this edition include the following: a) Clause 7.1 - adds reference to the fatigue design of AASHTO LRFD; b) Clause 7.5 - adds minimum thickness for aluminum poles; c) Clause 5.1 - clarifies which types of fasteners and special tools are permitted; and d) Scope - adds fibre reinforced poles. The purpose of this Standard is to ensure, through the provision of minimum requirements for construction, the mechanical strength aspects, electrical features, as well as the design-load capabilities of lighting poles. Scope 1.1 This Standard applies to free-standing poles of ferrous metal, aluminum, polymeric, concrete, fibre reinforced structures, and wood, and to their accessories, for use in the support of lighting equipment having ratings of 600 V and less, and intended to be installed in the commercial and industrial nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I. 1.2 This Standard applies to poles used for the support of lighting equipment, such as luminaires, electric signs, and traffic lights. The poles may also serve as supports for aerial conductors, PV modules, and wind turbines used to supply the lighting equipment and, in the case of concrete or metal poles, provide wireways for conductors entering the poles. 1.3 This Standard applies to the electrical features of poles as well as to the mechanical strength aspects and the ability to support their design loads. 1.4 This Standard does not apply to the erection of poles or the installation of accessories on site. Note: Lighting Poles for residential applications less than 4 m in height may be evaluated to the requirements of CSA CSA C22.2 No 250.0 for electrical safety only, and be marked NOT EVALUATED FOR STRUCTURAL STRENGTH and N'A PAS ETE EVALUE QUANT A LA RESISTANCE STRUCTURALE. 1.5 In this Standard, "shall" is used to express a requirement, i.e., a provision that the worker is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
