Knob & Tube wiring in itself is not dangerous. In fact, the tradesmen that first manufactured it built it to last.

Knob & tube wiring was used extensively in houses built from 1880 to the 1940s. This type of wiring is made with copper conductors attached to porcelain insulating tubes and knob insulators nailed into place, hence the name. The main problem with this method of wiring is that is can’t handle the electric load of today’s appliances. Think about what a house in 1880 would have in the way of electrical appliances versus household of today with electric ovens, refrigerators, TVs, microwaves, even a modern day air conditioning system. It’s no wonder knob and tube wiring would have issues.
Another huge red flag about knob & tube wiring is that this system was developed before circuit breakers and fuse boxes. Knob and tube systems also don’t have grounding wires or components. Some homeowners have tried to bypass this by installing three pronged outlets in areas where appliances need it but this doesn’t provide grounding, just an extra hole for the third prong, basically.
