Safety standards
 4. (1) All distribution systems and the electrical installations and electrical equipment forming part of such systems shall meet the primary safety standard set out in subsection (2) by meeting the safety standards set out in subsections (3), (4), (5) and (6). O. Reg. 22/04, s. 4 (1). (2) All distribution systems and the electrical installations and electrical equipment forming part of such systems shall be designed, constructed, installed, protected, used, maintained, repaired, extended, connected and disconnected so as to reduce the probability of exposure to electrical safety hazards. O. Reg. 22/04, s. 4 (2). (3) All electrical installations operating at 750 volts or below that are not a direct part of a distribution system shall meet the following safety standards: 1. Operating electrical equipment shall be maintained in proper operating condition. 2. Adequate space shall be provided around electrical equipment for proper operation and maintenance. 3. Live conductors shall be adequately insulated or barriered to prevent inadvertent contact. 4. Persons who have reason to work on electrical wiring or touch live conductors shall have ready access to a means to disconnect the live conductors before working on the wiring or touching the conductors. 5. Disconnecting means shall effectively disconnect and be operable without undue hazard. 6. Metal parts of an installation that are not intended to be energized shall be effectively grounded. 7. Electrical installations shall be carried out so as to minimize the possibility of contributing to or causing a fire or explosion. 8. Electrical installations shall be carried out so as to minimize the possibility of insulation damage or deterioration. O. Reg. 22/04, s. 4 (3). (4) All overhead distribution lines, including secondary distribution lines, shall meet the following safety standards: 1. Operating electrical equipment shall be maintained in proper operating condition. 2. Adequate space shall be provided around electrical equipment for proper operation and maintenance. 3. Energized conductors and live parts shall be barriered such that vegetation, equipment or unauthorized persons do not come in contact with them or draw arcs under reasonably foreseeable circumstances. 4. Metal parts of the installation that are not intended to be energized and that are accessible to unauthorized persons shall be effectively grounded. 5. Structures supporting energized conductors and live parts shall have sufficient strength to withstand the loads imposed on the structure by electrical equipment and weather loadings. O. Reg. 22/04, s. 4 (4). (5) All underground distribution lines, including secondary distribution lines, shall meet the following safety standards: 1. Operating electrical equipment shall be maintained in proper operating condition. 2. Adequate space shall be provided around electrical equipment for proper operation and maintenance. 3. Energized conductors and live parts shall be barriered such that equipment or unauthorized persons do not come into contact with them or draw arcs under reasonably foreseeable circumstances. 4. Metal parts of the installation that are not intended to be energized and that are accessible to unauthorized persons shall be effectively grounded. 5. Parts of the distribution system in proximity to the inside walls of a swimming pool shall be installed in such a way as to minimize the possibility of voltage gradients in the swimming pool. 6. Parts of a distribution system in proximity to propane tanks and natural gas pipelines shall be installed in such a way as to minimize the possibility of explosions under normal circumstances and operating conditions. O. Reg. 22/04, s. 4 (5). (6) Distribution stations shall meet the following safety standards: 1. Operating electrical equipment shall be maintained in proper operating condition. 2. Adequate space shall be provided around electrical equipment for proper operation and maintenance. 3. Metal parts of the installation that are not intended to be energized and that are accessible to unauthorized persons shall be effectively grounded. 4. Energized conductors and live parts shall be barriered such that equipment or unauthorized persons do not contact them or draw arcs under reasonably foreseeable circumstances. 5. Structures supporting energized conductors and live parts shall have sufficient strength to withstand the loads imposed on the structure by equipment and weather loadings. O. Reg. 22/04, s. 4 (6). (7) In this section, “weather loadings” means loads due to temperature, ice or wind acting on conductors and structures. O. Reg. 22/04, s. 4 (7).
