This is the first edition of CSA C22.2 No. 338, Type Class 2 power supplies (USB) and combination devices (receptacle/USB). It is one of a series of Standards issued under Part II of the Canadian Electrical Code.

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of the latest edition of CAN/CSA-C22.2 No. 0.

Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided the following direction for the interpretation of standards under its jurisdiction: The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials or construction, and when a relevant committee interpretation has not already been published, CSA’s procedures for interpretation shall be followed to determine the intended safety principle.

This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1

This Standard applies to wiring devices rated 60 A or less and intended for use in accordance with CSA C22.1, Canadian Electrical Code, Part I, as follows:

a) Class 2 power supply outlets (USB) installed on

i) faceplates of an outlet box;

ii) a yoke similar to an outlet box mounted receptacle; or

iii) mounted on a wall as a self-contained device; and

b) combination devices (receptacle/USB, general use switch/USB).

1.2

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 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.

1.3

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

This is the harmonized CSA Group and UL standard for Molded-Case Circuit Breakers, Molded-Case Switches, and Circuit-Breaker Enclosures for Use with Photovoltaic (PV) Systems. It is the First edition of CSA C22.2 No. 305 and the First edition of UL 489B.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1

These requirements cover molded-case circuit breakers, molded-case switches, and circuit-breaker enclosures rated up to 1500 V dc, intended for use with photovoltaic (PV) systems and Ref. No. 1 of Annex B.

1.2

These requirements are intended to be used in conjunction with the requirements in Ref. No. 2 of Annex B, except as modified or supplemented by this Standard.

1.3

These requirements do not cover molded-case circuit breakers or molded-case switches intended for use in battery circuits.

This is the first edition of CSA C22.2 No. 292, Dc arc fault protection for photovoltaic applications, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.

This Standard is intended to replace the requirements previously contained in CSA TIL M-07.

Arc fault protective devices are often embodied in combination with another device. As such, the user of this Standard may need to reference additional requirements as found in CSA C22.2 No. 5, CSA C22.2 No. 144.1, CSA C22.2 No. 21, CSA C22.2 No. 42, or elsewhere, as applicable.

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0, General Requirements — Canadian Electrical Code, Part II.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1

This Standard applies to dc arc fault protective devices (DC-AFPDs) and devices incorporating arc fault circuit protection intended for use in direct current circuits in photovoltaic (PV) systems having a maximum voltage rating of 1000 V dc and intended for installation in accordance with the rules of the Canadian Electrical Code, Part I.

1.2

This Standard contains construction, test, and marking requirements for DC-AFPDs and is designed to be used in conjunction with CSA CAN/CSA-C22.2 No. 5, CSA C22.2 No. 144.1, CSA C22.2 No. 305, and CSA C22.2 No. 107.1 as applicable.

1.3

A DC-AFPD is intended to detect and mitigate the effects of arcing faults that can pose a risk of fire ignition under certain conditions if the arcing persists. A DC-AFPD is not intended to detect glowing connections.

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 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.
