Peter,
The Canadian Electrical Code is a publication issued by CSA in several parts. Among these are Part I, which establishes safety standards for the installation and maintenance of electrical equipment, and Part II, which consists of safety standards governing the construction, testing, and marking of electrical equipment.
Question #1) CAN/CSA-C22.1 is the Canadian Electrical Code
This Standard covers the following:
Scope
This Code covers all electrical work and electrical equipment operating or intended to operate at all voltages in electrical installations for buildings, structures, and premises, including factory-built relocatable and non-relocatable structures, and self-propelled marine vessels stationary for periods exceeding five months and connected to a shore supply of electricity continuously or from time to time, with the following exceptions:
(a) Installations or equipment employed by an electric, a communication, or a community antenna distribution system utility in the exercise of its function as a utility, and located outdoors or in buildings or sections of buildings used for that purpose; and
(b) Equipment and facilities that are used in the operation of an electric railway and are supplied exclusively from circuits that supply the motive power; and
(c) Installations or equipment used for railway signalling and railway communication purposes, and located outdoors or in buildings or sections of buildings used exclusively for such installations; and
(d) Aircraft; and
(e) Electrical systems in ships which are regulated under the Canadian Coast Guard, Ship Safety Branch, Ship Safety Electrical Standards.
For mines and quarry applications, see also CSA Standard CAN/CSA-M421.
Rationale. The Scope states the extent and coverage of the requirements of the CE Code, Part I, as well as the limitations or exceptions.
Intent. We intend the CE Code, Part I, to apply to all voltages because even when voltages are low enough not to be a shock hazard, a startle-effect might lead to an injury and/or a condition may occur which creates a thermal hazard.
The CE Code, Part I, does not apply to electrical installations used by utilities that are electrical, communication, or a community antenna distribution system, in their function as a utility, but does apply to the wiring system and equipment used in their buildings for general office use. building used as a receiving/transmitting station for a community antenna distribution system, a central exchange building used by a communication utility, or a generating station used by an electrical utility is not covered, and portions or sections of their buildings that are closed to the public and used primarily for this purpose are not included in the Scope.
It is not the intention that requirements in the CE Code, Part I, apply to electrical installations that are installed on rights of way or public thoroughfares by a utility.
In spite of the overall coverage implied by the word “all” in the first sentence of the Scope, it was never the intent, or so we believe, that the CE Code, Part I, apply to the ordinary automobile. The CE Code, Part I, does apply to such portions of the electrical wiring and electrical equipment as lighting and power circuits connected to an external source of power, eg, in a motor home or a recreational vehicle.
Luminaires, regardless of voltage, can create thermal hazards and thus should not be excluded from the requirements of this Code. The intent of the word “premises” in the Scope is to include a house or building with its grounds and appurtenances.
Generators or alternators used for supplying power from the unit to portable tools and/or lighting units should be approved as otherwise required by the CE Code, Part I.
The CE Code, Part I, does not apply to that portion of electric railways used in their operation and supplied from that circuit supplying the motive power.
The CE Code, Part I, does not apply to electrical installations and electrical equipment used for railway signalling and railway communication purposes, and located outdoors, or in buildings or parts of buildings used exclusively for such electrical installations. However, portions of the buildings used for offices are covered.
The CE Code, Part I, does not apply to aircraft of any type.
The CE Code, Part I, does not apply to self-propelled marine vessels, unless the vessels are stationary for periods longer than 5 months and are connected to a shore supply of electricity even for short periods. A vessel anchored in a harbour for 6 months and supplied with power from the shore is an example. Also, electrical systems on ships regulated under the Canadian Coast Guard Ship Safety Branch are not covered by this CE Code, Part I.
A note indicates where mines are covered; they are not included or excluded in the foregoing Scope, since CSA Standard M421 states that it is to be used in conjunction with the CE Code, Part I.
Question #1 Cont'd.) CAN/CSA-C22.2 is the Canadian Electrical Code for Electrical Equipment
This Standard covers the following:
1. Scope and Object
1.1 Scope of this Standard
This Standard covers definitions, construction requirements, marking, and tests of a general nature that are applicable to all or several of the individual standards of Part II of this Code.
1.2 Scope of Individual Standards
Each individual Standard covers definitions, construction requirements, marking, and tests for a single class or a closely allied group of electrical equipment.
1.3 Object of Canadian Electrical Code, Part II
The object of Standards issued as portions of Part II of this Code is prevention of injury to persons and damage to property through proper design, good construction, and high quality workmanship. To this end, there are safety standards for the design and construction of electrical equipment for use throughout Canada in conformity with the Rules of Part I of this Code.
1.4 Object of this Standard
This Standard shall form a part of, and be read in conjunction with, all individual standards to which the requirements of this Standard may apply, except that, where an individual standard contains requirements that are at variance with those of this Standard, the requirements of the individual Standard shall take precedence.
1.5 Object of Individual Standards
1.5.1
Individual Standards contain only the special requirements applicable to the equipment that they cover.
1.5.2
Where an individual Standard makes reference to another Standard, requirements in the individual Standard at variance with those in the other Standard shall take precedence.

Peter, you can purchase the Part II Standards by contacting CSA in Toronto @ 178 Rexdale Blvd, Etobicoke, Ontario @ 416-747-4000.
Question #2
Peter, follow the manufactures spec sheet for the PT's as indicated in the previous post, which was taken from the CSA Standard.
