Standard

1.1 This Standard applies to single-phase and polyphase transformers of the dry type for supplying energy to power, heating, and lighting circuits and designed to be installed and used in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard applies to multiwinding and autotransformers rated 72.5 kV class and less. 1.3 This Standard applies to transformers for use in nonhazardous indoor and outdoor locations.

1.1 This Standard specifies the technical requirements for the interconnection of distributed resources (DR) and distribution systems up to 50 kV line to line. This Standard covers all distributed resource technologies with an aggregate capacity of 10 MW or less at the point of common coupling (PCC).

1.2 This Standard does not define the maximum DR capacity or the upper voltage limit for installations that are interconnected with a single PCC or connected to a given feeder.

1.3 This Standard covers the interconnection of (a) inverter-based DR systems and distribution systems where the PCC is at medium voltage; and (b) generator-based DR systems and distribution systems where the PCC is at low or medium voltage. See CAN/CSA-C22.2 No. 257 for interconnections of inverter-based DR systems and distribution systems where the PCC is at low voltage.

1.4 The objective of this Standard is to specify minimum requirements for the (a) safety of persons; (b) continuity of service; and (c) protection of property.

1.5 This Standard does not apply to secondary network connections and does not address (a) protection of the power producer's facility; (b) operating requirements for DR units; (c) intentional islanding; (d) transmission system impact and upgrades; (e) planning, design, or operation of the distribution system or DR system; (f) metering, rates, tariffs, and other contractual or commercial issues associated with interconnection; or (g) interconnection of distributed resources and distribution systems that are not ultimately connected to a province-wide or regional electricity grid (i.e., remote locations).

This standard provides requirements for the application, location, installation, performance, testing, and maintenance of electronic premises security systems and their components. Provisions define the means of signal initiation, transmission, notification, and annunciation; the levels of performance; and reliability.

This standard protects life and property from fire through the standardization of design, installation, maintenance, and testing requirements for water mist fire-suppression systems.

This standard covers performance requirements for emergency and standby power systems providing an alternate source of electrical power in buildings and facilities in the event that the normal electrical power source fails. Systems include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to the selected circuits.

This standard provides criteria for developing pre-incident plans to help responders effectively manage emergencies so as to maximize protection for occupants, responding personnel, property, and the environment.

This standard provides technical requirements for exhaust systems that will protect lives and property from fires and explosions and minimize damage in the event that such fires and explosions occur.
