1. Scope Section A - Transformers for Luminous-Tube Signs A1.1 This section applies to transformers for luminous-tube signs of portable and stationary types, for potentials up to and includ ing 600 volts low-potential, and l5,000 volts open-circuit high-potential, designed to be employed in accordance with the rules of the Canadian Electrical Code, Part I. It includes: (a) outdoor types - Enclosed , non-weatherproof construction intended for use within the enclosures of signs; (b) indoor types:,, (i) enclosed , including pendent-type transformers (and standing-type transformers); and,, (ii) open or skeleton-type transformers; and (c) reactors, if supplied as part of a transformer. Having sealed-in (ie, compound-sealed) windings. A1.2 Transformers covered by this Section for use as auxiliary equ ipment for signs used for general advertising and display purposes. Section B - Transformers for Oil- or Gas-Burner Ignition Equipment B1.1 This Section applies to transformers for oil- and gas- burner ignition equipment for potentials up to and including 600 volts low-potential, and 15,000 volts open-circuit high- potential, designed to be employed in accordance with the rules of t he Canadian Electrical Code, Part I. Note: The terms low-potential and high-potential are used herein, respectively, for primary or low-voltage, and secondary or high-voltage. B1.2 Transformers covered by this Section are intended for use as auxiliary equipment for oil- and gas-burning apparatus. Section C - Transformers for Cold-Cathode Interior Lighting C1.1 This Section applies to transformers for cold-cathode, high-voltage, luminous tubing, for potentials up to and including 600 volts low-potential and 15,000 volts open-circuit high-potential, designed to be employed in accordance with the rules of the Canadian Electrical Code, Part I. Note: The terms low-potential and high-potential are used herein for primary or low-voltage and secondary or high- voltage respectively. It includes: (a) (i) Enclosed transformers having sealed-in windings; and (ii) Open or skeleton-type transformers; and (b) Reactors, if supplied as part of a transformer. C1.2 It does not apply to transformers for lighting systems under 1,0 00 volts. C1.3 Transformers covered by this Specification are intended for use as auxiliary equipment for interior lighting.
