Description / Abstract:

This Standard applies to the design, installation, operation, maintenance, and testing of emergency generators and associated equipment for providing an emergency electrical 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.

3) Normative provisions of this Standard are not limited to the installations where an emergency generator is used as the NBCC required emergency power supply source to the “life safety equipment”.

4) For guidelines on the use of emergency electrical power supply equipment for purposes beyond the provisions of Clause 1.1, see Annex D.

5) It is intended by the scope of this Standard that equipment other than “life safety equipment” could be connected to the emergency generator (see Clause 6.4.1).

6) For electrical power supply systems designed and installed to operate for purposes other than those specified in Clauses 1.1, the electrical power supply system should meet the requirements of this Standard, where practical, and in conjunction with the guidelines of Annex E of this Standard. 

This Standard does not cover

a) any emergency electrical power supply provided from storage batteries or other sources of uninterrupted power supply (UPS); and

b) design and construction of unit equipment for emergency lighting that complies with CSA C22.2 No. 141.

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
