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 Transport Canada, Marine Safety, Ship Electrical Standards.
For mines and quarry applications, see also CSA Standard CAN/CSA-M421.
This Code and any standards referenced herein do not make or imply any assurance or guarantee by the authority adopting this Code with respect to life expectancy, durability, or operating performance of equipment and materials referenced herein.
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. The CE Code, Part I, is intended to apply to all voltages because even when voltages are low enough not to be a shock hazard, a startlemight 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 the utility buildings for general office use. A 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 utility 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 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.
0
The CE Code, Part I, does not apply to selfmarine 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.
