Knob and Tube Wiring Experts in Toronto

Knob And Tube Wiring

With many homes and buildings in the area being decades old, it’s quite common to find knob and tube in Toronto.  More specifically, if your home was built between 1900 and 1945, you likely have older wiring, which is no longer considered standard or secure. 

What exactly is knob and tube wiring? It’s an older-style electrical system that uses porcelain knobs and tubes to insulate and secure electrical wiring. The knobs support individual wires that run along wooden beams, the ceramic tubes pass through the beams.

Is Knob and Tube Wiring in Old Toronto Houses Safe?

The number one question around outdated wiring is whether or not it’s safe. There are several concerns with knobs and tubes in Toronto that homeowners should be aware of.

A quick summary of issues includes:

  • It’s an ungrounded system, which creates a greater risk of damage or injury.
  • Since it is very old, it has likely deteriorated and cracked, which can lead to a fire.
  • The original switches and receptacles are not CSA-approved.
  • Newer wiring has often been improperly connected to knob and tube wiring, resulting in dangerous conditions.
  • Knob and tube wiring only exist in 15-amp ratings, which will not support most modern devices that require more power to function properly.

If you’ve discovered outdated wiring in your home, now is the time to complete a knob and tube replacement. Ensure your home is as safe and as efficient as possible by making the right decision to have your electrical upgraded by a licensed electrician.

Frequently Asked Questions

The common life expectancy of knob and tube wiring is 25 years, due to the rubberized cloth insulation used on the wires beginning to break down. While the wiring itself remains functional, the deterioration of insulation increases the risk of injury and damage that can cause more serious issues. As this type of wiring is an outdated option, dating back to the early to mid-1900s, the homes that still have it today are living on borrowed time.

Knob and tube wiring can only exist in 15-amp ratings, which is a very low current on the general scale of wiring methods. Most modern devices require more power than 15-amps to function properly, which means that the devices may not work, or the wiring will be working much harder than it is designed to. Neither of these circumstances are ideal for your home, nor are they safe.

There are several concerns surrounding knob and tube electrical, as it is outdated, which means its level of safety is questionable. The following are issues associated with this type of electrical wiring that homeowners should be aware of. As an ungrounded system, it increases the risk of injury; deterioration or cracking likely has happened over time, which can lead to an electrical fire; and newer wiring is often connected to knob and tube wiring, which creates dangerous conditions. Langstaff and Sloan Inc advises all homeowners to replace their knob and tube wiring. Having a licensed electrician upgrade your electrical will ensure your home is as safe as possible.

While you can tell if a knob and tube wire is active by following the wires and seeing where they lead to, the safest way is to hire a professional. At Langstaff and Sloan, we send one of our licensed electricians to inspect your home’s wiring and see what condition it is in. Alternatively, if you have some technical knowledge of electricity, you may also use a voltage stick, otherwise known as a “tick buster.” By inserting the probes into the knob and tube fixture, you may test the alternating current. If the result is within 110 to 120 volts, the wire is live, so proceed with caution.

While many homes built between 1900 and 1945 have knob and tube wiring, there are several concerns associated with this wiring method that should not be ignored. It is an ungrounded system, which increases the likelihood of damage or injury. This is not only because it is old, meaning it may have deteriorated or cracked, but also because modern devices are not properly supported by it. If your home is suspected to have or has been confirmed to have knob and tube wiring, it is time to call Langstaff and Sloan Inc and book your wiring replacement.
