Up until the 1940s, knob and tube wiring was considered the best way to wire a home. Ceramic knobs could be easily nailed to joists, wire fed through the knobs, and matching ceramic tubes used to protect the exposed wires.
However, this type of wiring predates the common use of heavy home appliances like microwaves, washers, dryers, dishwashers, and HVAC systems. Additionally, many knob and tube wiring systems have been repeatedly repaired and even circumvented, rendering them even more of a hazard.
Quite a few homes have had knob and tube wiring replacement, but owners find remnants of previous systems still in place.
