Preface<\/strong><\/p>\n

<\/p>\n

This is the fifth edition of CSA C22.2 No. 74, Equipment for use with electric discharge lamps<\/em>, 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.<\/p>\n

<\/p>\n

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

<\/p>\n

The following sections have changed in this edition:<\/p>\n

<\/p>\n

a) spacings requirements \u2013 Clause 4.20.5, Part 1;<\/p>\n

<\/p>\n

b) inrush current \u2013 Clause 4.24.4, Part 1;<\/p>\n

<\/p>\n

c) risk of electric shock test \u2013 Clause 6.11, Part 1;<\/p>\n

<\/p>\n

d) anti arcing test method \u2013 Clause 6.12, Part 1; and<\/p>\n

<\/p>\n

e) harmonics proposal \u2013 Clause 4.25, Part 1 and Clause 4.19, Part 2.<\/p>\n

C22.2 No. 74-16 – Part 1 – Ballasts for use with fluorescent lamps<\/strong><\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

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.<\/p>\n

<\/p>\n

1.2<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

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.<\/p>\n

<\/p>\n

1.2<\/p>\n

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.<\/p>\n

<\/p>\n

1.3<\/p>\n

In this Part of the 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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n

C22.2 No. 74-16 – Part 3 – Ancillary equipment \u2014 Starters, holders<\/strong><\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

This Part of the Standard applies to starters of both the automatic and manual types that are intended for use in conjunction with fluorescent ballasts covered in Part 1 of this Standard for the operation of preheat type electric-discharge lamps, in accordance with the Rules of Part I of the Canadian Electrical Code.<\/p>\n","protected":false},"excerpt":{"rendered":"
