Preface

This is the fifth edition of CSA C22.2 No. 74, Equipment for use with electric discharge lamps, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1996, 1992, 1969, and 1954.

This edition incorporates, in three parts, requirements for fluorescent light ballasts, high-intensity discharge lamp ballasts, and ancillary equipment such as lampholders and starters.

The following sections have changed in this edition:

a) spacings requirements – Clause 4.20.5, Part 1;

b) inrush current – Clause 4.24.4, Part 1;

c) risk of electric shock test – Clause 6.11, Part 1;

d) anti arcing test method – Clause 6.12, Part 1; and

e) harmonics proposal – Clause 4.25, Part 1 and Clause 4.19, Part 2.

C22.2 No. 74-16 – Part 1 – Ballasts for use with fluorescent lamps

Scope

1.1
Part 1 of this Standard applies to ballasts of the resistance, reactance, and electronic (solid state) types for use with fluorescent lamps, involving potentials of 2500 V to ground or less during either starting or running conditions, whether intended for mounting in a luminaire or otherwise, and designed to be employed on circuits of not more than 600 V between supply conductors in accordance with the Canadian Electrical Code, Part I.

1.2
In this Part of 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” 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.

C22.2 No. 74-16 – Part 2 – Ballasts for use with high-intensity discharge lamps

Scope

1.1
This Part of the Standard applies to ballasts for use with high-intensity electric discharge lamps of the metallic vapour types including low-pressure sodium and similar types, intended for permanent installation on branch circuits of not more than 600 V between conductors, in accordance with the Rules of the Canadian Electrical Code, Part I.

1.2
This Part of the Standard does not apply to ballasts intended for use in cold cathode, luminous tube (neon), and xenon lamps as specified in CSA C22.2 No. 255.
