I have an old stone 18th C. Pennsylvania farm house. In several rooms, wall sconces were installed when the house was first electrified - with knob & tube wiring. The knob and tube wired to old outlets are being rewired with romex to handle modern heavier loads. But for the sconces, I wanted to explore the possibility of connecting the knob & tube wiring from a low voltage 12v source.
- I imagine 12 volt is safer than 120 volt. I have read here elsewhere that NFPA70 (National Electic Code) does not exclude use of knob & tube, but that some insurance companies will not insure a house with active knob & tube. I wonder how an insurance underwriter would react to the use of old knob & tube for 12v lighting only?
- Would a 12v system work with K&T wiring? And old sconces?
