Im writing a paper on thisI'm going to college to be an electrician, I don't have a whole lot of experience with thisI know it's no longer used in residential, commercial or industrial companiesIts no really a fire hazard but it could beThat's about itI'm having a hard time finding information on this and Wikipedia isn't allowed to be used for reference infoIt's actually bannedLolAny help would be appreciated.

Answer:

Knob and tube is widely used here in West Virginia and in many other places with older homesI replace it all the timeI am an electrician and a residential building contractorIt IS really a fire hazardThe wire is aluminum and is always undersized for the amount of current that passes through itI have actually been burned by it after it was off for a minuteThe worst problem with it is that people replace their old service panels with newer models and don't upgrade the wire tooThe insulation on the wire falls apart leaving bared wiresThey are aluminum wires and most of the new outlets are made to be used with copper wires so the dissimilar metals pose more problems as time goes by.
