mikesh,yes it is infact an Ontario amendment(my mistake).The rule # is
2-028 Miscellaneous sub-rule (2)
Subject to sub-rule (5) of rule 2-024,any electrical equipment used or capable of being used or adapted to serve or preform any particular purpose or function when connected to an electrical installation shall be approved before being so connected unless the connection is made for the purpose of inspection or testing of the equipment under this code.
Sub-rule (3)
Any electrical equipment that consists of an assembly or combination of other electrical equipment is subject to this code respecting approval,and is not approved by reason only that any or all of the component parts thereof have been individuality approved.

Trying to rationalize(3)but it seems to be missing a word or two?Thats why i think it has to be approved as a whole assembly?
How do you read it?
thanks
