The following sections have changed in this edition:

c) risk of electric shock test - Clause 6.11, Part 1;
d) anti arcing test method - Clause 6.12, Part 1; and
e) harmonics proposal - Clause 4.25, Part 1 and Clause 4.19, Part 2.

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.
2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.
3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization - Code of good practice for standardization as "substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity". It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.
