The 2006 Canadian Electrical Code, Part I includes many important changes in technical requirements in areas such as:

• bonding and grounding conductor sizing, ground electrode types, grounding of AC circuits supplied from two different sources, and impedance grounded systems
• supplementary protectors
• hazardous locations – classifications, high pressure sealing, wiring methods for Class I
• ground fault circuit interrupter requirements expanded
• sewage lifts and treatment plants
• sunlight resistant materials
• shock and arc flash protection
• 347 V ballast disconnect means
• fire pump installations
• disconnecting means for spas and hot tubs
• airport installations
• neutral supported cable ampacities
• interconnection of power sources

This twentieth edition of the Canadian Electrical Code, Part I, was approved by the Committee on the Canadian Electrical Code, Part I, and by the Regulatory Authority Committee at their June 2005 meetings in Kelowna, British Columbia. This twentieth edition supersedes the previous editions, published in 1927, 1930, 1935, 1939, 1947, 1953, 1958, 1962, 1966, 1969, 1972, 1975, 1978, 1982, 1986, 1990, 1994, 1998, and 2002.

Sections 0 to 16 and 26 are considered general sections, and the other sections supplement or amend the Various requirements were revised as a result of the continuing efforts toward harmonization. In addition, there are significant changes to Sections 2, 10, 18 (particularly in Appendices B and J), 26, and 32. Sections 74 and 84 have been revised considerably to reflect new technology and industry practices.

A new subsection was added to Section 22 to contain the requirements for Sewage Lift and Treatment Plants.

A new Appendix I has been added listing the interpretations that have been approved since the last edition, in the cases where the Rule in question has not been clarified yet. A new Appendix K has been added giving the fundamental safety principles contained in IEC 60634-1.

Object

The object of this Code is to establish safety standards for the installation and maintenance of electrical equipment. In its preparation, consideration has been given to the prevention of fire and shock hazards, as well as proper maintenance and operation.

Compliance with the requirements of this Code and proper maintenance will ensure an essentially safe installation. Safe installations may also be ensured by compliance with the objective-based fundamental safety principles of IEC 60364-1.

Compliance with these objective-based installation criteria by industrial and similar users may be achieved through the implementation of specific quality management programs or equivalent programs acceptable to the authorities adopting and enforcing this Code. Wiring installations that do not make provision for the increasing use of electricity may be overloaded in the future, resulting in a hazardous condition. It is recommended that the initial installation have sufficient wiring capacity and that there be some provision made for wiring changes that might be required as a result of future load growth.

This Code is not intended as a design specification nor as an instruction manual for untrained persons. The requirements in this Code address the fundamental principles of protection for safety contained in Section 131 of IEC 60364-1, which encompasses protection against electric shock, thermal effects, overcurrent, fault currents, and overvoltage.

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, as recognized by the regulatory authority having jurisdiction, and located outdoors or in buildings or sections of buildings used for that purpose;
(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;
(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 that are regulated under Transport Canada.

For mines and quarry applications, see also 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.

Notes Regarding “SMART” CD-ROM:This is a standalone, single-user license CD-ROM.

This SMART CD-ROM includes enhanced features such as:

• Complete text, tables, figures, and diagrams from both the 2006 CE Code and CE Code Handbook
• The CD is designed so you can easily differentiate between the mandatory CE Code and the Rationale and Intent from the Handbook.
• The most commonly used calculations such as individual and motor feeders, transformers, grounding and bonding, ampacity of conductors are computed automatically with the help of a calculator. All you have to do is answer the sequence of questions to end up with a final result for your particular situation.
• Three easy ways to navigate quickly within both documents – by search function, through the Index, and in the Table of Contents
