This Code specifies objectives to provide for the safety of persons, livestock, and property against dangers and damage that can arise from the use of electrical installations and to provide for the proper functioning of those installations. In addition, this Code sets objectives for the protection of property against damage, if the damage can lead to unsafe events or conditions for persons and livestock.

(a) design;
(b) selection of electrical equipment;
(c) erection and verification; and
(d) operation and maintenance.
 

1.3
This Code specifies technical provisions to address the safety objectives. The technical references in this Code are not exclusive and do not necessarily represent all acceptable solutions that might be considered to have a bearing on the objectives of this Code.

1.4
This Code and any standards referenced herein do not make or imply any assurance or guarantee with respect to the life expectancy, durability, or operating performance of the equipment and material referenced herein.
