Hi all. In the building I live in, some people I know have removed the ground plug from their three-pronged appliances in order to plug them into the house's older, two-wire setup. There is only a limited number of 3-conductor outlets in the house. I've urged them to stop doing this because of the dangers involved (Also not being GFCI'd), but ultimately they do it anyway. Now my question is, is this illegal for any reason? Does it violate any fire or electrical codes? Does having 3-pronged appliances ungrounded put the building 'out of compliance'?
