CSA Group CSA/ANSI C22.2 No. 298:21 National Standard of Canada American National Standard High voltage couplers

Preface

This is the second edition of CSA/ANSI C22.2 No. 298, High voltage couplers. It supersedes the previous edition published in 2016. 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 CSA C22.2 No. 0.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was prepared by the Subcommittee on High Voltage Couplers, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.

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.

This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.

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.”

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at

1 Scope

1.1

This Standard applies to locking-type, pin and sleeve type plugs, receptacles, power inlets, connectors, junction boxes, and live-end covers rated up to 1200 A (for single- and multi-pole) and above 750 V to 35 kV ac, 50/60 Hz or up to 1500 V dc and which shall have one or more pilot contacts for multi-pole configuration and above 750 V to 1000 V ac or dc for single pole configuration. These devices are intended to provide portable power from branch circuits, or are for direct connection to the branch circuit in accordance with the Canadian Electrical Code, Part I, or National Electrical Code (NEC) using portable power cables with copper conductors, for use in either indoor or outdoor, nonhazardous locations.

1.2

The products covered in this Standard are commonly, but not exclusively, used in the following applications:

a) open pit mining;

b) underground mining;

c) tunneling;

d) shore to ship power;

e) portable power equipment;

f) general industrial use; and

g) drilling.

1.3

This Standard does not apply to

a) products covered in CSA C22.2 No. 182.1 and UL 1682;

b) devices intended to be separated or connected under load; and

c) products covered in CSA C22.2 No. 282 and UL 2251.

1.4

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.

1.5

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.
