The Code covers all electrical installations for buildings, structures, and premises and is intended to apply to all voltages. Although low voltages might not pose a shock hazard, various conditions can lead to injury and damage to equipment, even at seemingly harmless voltage levels.

The Scope specifies the subjects that the Code covers. In addition, it lists subjects not covered so that the reader can determine what other requirements apply, as determined by the authority having jurisdiction. For example, the requirements for electrical systems on aircraft and ships are not covered in the Code but are regulated by Transport Canada. If an application is excluded from the Scope of the Code, the authority having jurisdiction should be contacted to determine the requirements that do apply.
