Knob and Tube Wiring Experts in Toronto
If your home was built between the 1900s and 1940s, it was likely constructed with knob and tube wiring. This is an older-style electrical installation, so named for the use of porcelain knobs and tubes to insulate and secure the wiring. Although this type is no longer the standard, it is still acceptable to perform replacement repairs and maintenance on existing knob and tube setups.
Given that in any instance, knob and tube wiring is at least 70 years old, it naturally has some notable deficiencies:
- Knob and tube wiring only exists in 15 amp ratings. Many modern devices require more power to function properly. There are additional overloading and fire hazards that can occur if the wrong fuse or type of extension cord is used.
- There is a distinct fire hazard present when the insulation around the wiring breaks down.
- Knob and tube wiring is not grounded, creating additional electrical dangers that need to be monitored.
- Some insurance companies will not write a policy for a home with knob and tube wiring, or will otherwise charge a premium for such policies.
Despite these risks, knob and tube wiring is not inherently unsafe. Toronto homes can still retain their vintage wiring setups provided the appropriately sized fuse or circuit breaker is used without any outlets being added to the original installation. A certified electrician will also need to inspect the wiring to ensure that all parts and conductors are in good condition.
