This is the second edition of CSA C22.2 No. 250.7, Extra-low-voltage landscape lighting systems. This Standard is one of a series of Standards issued under the Canadian Electrical Code, Part II. It supersedes the previous edition published in 2007.

This edition of the Standard updates the scope to cover safety extra-low-voltage (SELV) circuits.

This Standard contains specific requirements for extra-low-voltage landscape lighting systems and is intended to be used together with the requirements for luminaires contained in CSA C22.2 No. 250.0-18, Luminaires.

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

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

This Standard sets out minimum requirements for the design, construction and testing of electrical installations that supply electricity to appliances and equipment on construction and demolition sites, and for the in-service testing of portable, transportable and fixed electrical equipment used on construction and demolition sites.
In Australia only, for a single domestic residence intended to be occupied as a residential housing unit, or, adjoining units each with a separate exterior entry and intended to be occupied as residential housing units, the requirements of this Standard are modified as detailed in Appendix A.
NOTE: The National Construction Code (NCC) for Australia and New Zealand Building Code (NZBC) classification of building and structures is given in Appendix A.
In New Zealand only, for domestic housing sites where an electricity supply not exceeding 32 A single phase is installed specifically for the purposes of construction work, the requirements of this Standard are modified as detailed in Appendix A and Appendix J.
The requirements are intended to protect personnel, livestock and property from electric shock, fire and physical injury hazards that may arise from an electrical installation that is used with reasonable care and with due regard to the intended purpose of the electrical installation.
NOTE: For requirements and recommendations regarding safe working on or near electrical equipment and installations, refer to AS/NZS 4836 and to Codes of Practice or other guidance issued by the regulatory authorities.
This Standard applies to electrical installations associated with construction and demolition sites, which include—
(a) building work, excavation work, compressed air work and diving work;
(b) parts of buildings that undergo structural alterations, such as extensions, major repairs or demolition, to the extent that the work necessitates the provision of a temporary electrical installation;
(c) work on or in connection with the construction or maintenance of roads, airfields or airstrips, civil engineering works or bridges, or of the permanent way of a railway or tramway;
(d) dredging or salvaging work;
(e) the laying, lining or maintenance of pipes or cables;
(f) earthmoving work carried out with equipment requiring the use of other than manual power;
(g) any work in which explosives are used;
(h) site offices, cloakrooms, meeting rooms, dormitories, canteens, toilets, appliances and other facilities provided during any work referred to in Items (a) to (g); and
(i) land clearing in preparation for any work referred to in Items (a) to (g).

Scope

This Standard sets out a method for cable selection for those types of electrical cables and methods of installation that are in common use at working voltages up to and including 0.6/1 kV at 50 Hz a.c.
NOTE: Although the Standard specifically applies to a.c. installations, it may also be applied to d.c. installations.
Four criteria are given for cable selection, as follows:
(a) Current carrying capacity.
(b) Voltage drop.
(c) Short-circuit temperature rise.
(d) Economic optimization.
This Standard provides sustained current-carrying capacities and voltage drop values for those types of electrical cable and installation practices in common use in Australia. A significant amount of explanatory material is also provided on the application of rating factors that arise from the particular installation conditions of a single circuit or groups of circuits. Also, provided in Section 5 is information on cable selection based on short-circuit temperature limits.
NOTE: A number of worked examples on cable selection are included in Appendix A.
This Standard does not take into account the effects that may occur owing to temperature rise at the terminals of equipment and reference is necessary to AS/NZS 3000 and the individual equipment Standards.
NOTE: For ease of reference, an index of the Tables included in this Standard is provided in Appendix B.
