Abstract

Preface

This is the fifth edition of CSA C282, Emergency electrical power supply for buildings. It supersedes the previous editions published in 2005, 2000, 1989, and 1977.

Scope

1.1
This Standard applies to the design, installation, operation, maintenance, and testing of emergency generators and associated equipment for providing an emergency power supply to electrical loads
(a) in buildings and facilities when the normal power supply fails and an emergency electrical power supply is required by the National Building Code of Canada (NBCC); and
(b) of essential electrical systems, where emergency generators are intended for use in health care facilities (HCFs) in accordance with Clause 6 of CSA Z32.
Notes:
(1) For guidelines on emergency electrical power supply for life-support equipment, see Annex A.
(2) In this Standard, the term "building" also includes facilities.

1.2
Electrical power supply systems designed and installed to operate for purposes beyond emergency situations may be used for emergency electrical power supply provided that they meet the requirements of this Standard.
Note: For guidelines on the use of emergency electrical power supply equipment for purposes beyond emergency situations see Annex D.

1.3
This Standard does not cover
(a) any emergency power supply provided from storage batteries or other sources of uninterrupted power supply (UPS);
(b) application of an emergency power supply; and (c) design and construction of unit equipment for emergency lighting that complies with CSA C22.2 No. 141.

1.4
In CSA Standards, "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; "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 (nonmandatory) to define their application.
