The new rule only applies to new fluorescent fixtures that are supplied by voltages exceeding 150 Volts to ground. I never saw one yet because I have only worked on older fixtures and never had to install a new one this year.
Look at 2006 CEC -
(4)Each fluorescent luminaire installed on branch circuits with voltages exceeding 150 volts-to-ground shall be:
(a) provided with a disconnecting means integral with the luminaire that simulataneously opens all circuit conductors between the branch circuit conductors and the conductors supplying the ballast(s); and
(b) marked in a conspicuous, legible, and permenant manner adjacent to the disconnecting means, identifying the specific purpose.
The description of the integral disconnect I guess could be anything, switch, plug, just as long as it does what the rule says.
Wish I could give you a picture of one but I never saw one.
I would say that they would not be able to sell 347V fixtures in Canada without one anymore because it has to meet the CSA standard. Since the CSA wrote the code book you would think that they updated their CSA Standard on the fixtures.
Hope this helps.
