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. /
