Knob and tube wiring is also known as open wiring and was very common in the 1900s to 1940s as it was the only way to wire a house for electricity. Knob and tube systems are technically safe but only if they have been unaltered, well maintained and was installed by a very competent electrician. Typically, homeowners find these systems covered in insulation which can cause major problems for the home because of the heat that is stored which can cause a fire. Most of these homes were built over 60 to 100 years ago and should upgrade their systems for safety reasons.
Key Takeaways:
- Knob and tube wiring is safe if the system hasn’t been altered and it has been maintained. You would need the repairs made by a competent electrician.
- When insulation is installed over tube wiring, it creates danger as it can lead to a fire due to all of the heat that is being stored.
- Knob and tube wiring is extremely old and is usually only found in homes that were built about 60 to 100 years ago as it was the only way to wire a home back then.
“Realistically, complete replacement of the old wiring is the best option.”
