In this post we’ll provide answers to some of the most common knob and tube wiring FAQs.
When was knob and tube wiring used?
Knob and Tube wiring (aka open wiring or K&T wiring) is now obsolete but it was the standard form of electrical wiring used in Canada and the United States between the late 1800s and the mid 1930s. That means, if you own a home or you are considering buying a home that is pre-1940s, it will most likely have knob and tube wiring installed.
Is knob and tube wiring dangerous?
No, in and of itself, K&T wiring is not inherently dangerous. However, because of its age, or if the knob and tube wiring has been modified or updated incorrectly, it could be a potential safety hazard. It’s also important to note that there are no ground wires in K&T wiring so you cannot plug in any 3-pronged appliances. Our Abbotsford electricians recommend replacing knob and tube electrical wiring to bring your home up to today’s electrical standards.
Will I be able to get insurance for knob and tube wiring?
Since old K&T wiring violates current electrical code standards most Canadian insurance companies are reluctant to offer coverage and recommend replacing knob and tube wiring. It may be challenging to find but there are a few insurance companies that are still willing to provide K&T wiring insurance, but you will be required to provide proof of an electrical inspection by a certified electrician.
How can I tell if I have knob and tube wiring?
Most electrical wiring is sealed within the walls of your home so it may be difficult to tell if you have K&T wiring, even if some of your outlets are only 2-prong. If you have an attic or basement, most likely the wiring will be visible and easy to inspect. If you suspect your home has this out-dated wiring and you need help, call our Abbotsford electricians at 604-308-6195 and request an electrical safety inspection.
What is the cost to replace knob and tube wiring?
Old, unsafe wiring can be a real fire hazard so the cost of replacing K&T wiring is always warranted. In most cases the old knob and tube wiring doesn’t have to be completely removed. It can simply be disconnected and new wiring installed beside it, which will help to keep costs at a minimum. If your home must be rewired, always hire a qualified election. If you are considering buying an older home that has knob and tube wiring, we recommend you hire a qualified electrician to provide an accurate estimate on the cost to replace the old wiring.
