I believe this has come up before. I still see this a lot in older homes that have knob and tube, both installed by 'electricians' and home owners. They would replace old light fixtures with new metal ones, even though they have no equipment grounding. These are just average rectangle shaped fluorescent 'metal' fixtures you pick up at home depot or Lowes etc.. , with no gfci protection and no ground hook up.
I ask one guy about 2008 NEC 410.42, he says the 'painted metal fixture' is insulated from the egc and other conducting surfaces and therefore is in compliance. I asked about a line to case fault and if a home owner is changing the lamp, isn't it possible for the home owner to be a 'conducting' surface then ? I have not seen too many all plastic fluorescent fixtures that a lot of people like to install in their homes, but that is really the only way you can truly 'insulate' a fixture.
Am I missing something somewhere in the code concerning this issue?
