38、to be installed in airport field lighting series circuits for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I.1.2 This Standard applies to transformers that consist of primary and secondary coils that are wound upon a core, the assembly being enclosed in a water
39、proof case. The primary coil is connected into the series circuit and the secondary coil to the light fixture lead by means of plug/receptacle connectors. The receptacle portion of the connector is provided with the transformer to mate with the plug portion on the series circuit and light fixture ca
40、bles. The transformer receptacle portion may be either built into the transformer body or moulded into the ends of transformer leads.1.3 Transformers constructed to meet the requirements of this Standard are suitable for continuous outdoor service in ambient temperatures from a minimum of 55 C to a
41、maximum of +65 C and for direct earth burial.1.4 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user 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” i
42、s 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
43、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.2 Reference publicationsThis Standard refers to the following publications, and where such reference is ma
