I have k&t wiring in my outcoves in my attic. How can I tell if it is still in use on my electrical system.
My wall fixtures are 3 prong but have limited # of them in each room. My circut panel is switches and not screw in bulbs. Is there a device to test wires in attic to tell if they are still live or just not removed when wiring was rewired.Inspector said when I bought house said there was about 30% still in house but did not remove fixtures to see for sure, so he was not sure
