Do you know how to tell if knob and tube wire is live or not?
If you live in an older model of a house, you may have seen wire circuits that are connected into rounded circular pieces, these are what you call the knob and tube wirings.
This type of wiring is popular in older types of homes, especially those built in the 1900’s up to the early years of the 1950’s. Although it isn’t already used in new houses, other old house models still keep on using this type of wiring.
As what we may have known, older wirings can become quite dangerous and become prone to fire accidents.
