In reguards to the code change in Article 410.130(G) I am very surprised that the powers to be did not also make it mandatory that you post a sign next to the disconnecting means that says. All qualified personnel shall turn the disconnecting means to the off position before disconnecting the wires to the ballast. I read that this change was made because a large number of so called qualified people are getting electrocuted. I guess turning off the light switch and using a flashlight never entered their minds. The majority of the code changes in the 2008 code I find to be very funny. Like posting a sign on the panel telling the so called qualified electrician that Phase B is 208V so he will know not connect a 120V receptacle to it. NEC for dummies
