If you have an older home that was built between 1900 – 1940, you’re probably familiar with it or even have an existing knob and tube electrical system in your home.
Maybe you have had some electrical upgrades since then, maybe you haven’t. What you should know is that knob and tube, Although knob and tube was once deemed an electrical system of choice, by today’s electrical safety standards, it is no longer safe and should be replaced.
The name “knob and tube” is pretty self-explanatory – it’s named after the ceramic knobs that are used to support the ceramic tubes that encase the wires. The knobs hold the tubes in place as they pass through the wood framing of your home.
One of the biggest differences between modern wiring and knob and tube is that the knob and tube system runs white and black wires separately.
So what’s the problem?
Since the knob and tube system uses no ground wire, there’s no protection when a fault occurs. As a result, you increase your risk of shocks and fires.
Today, these wires are bundled together with a ground wire in a single plastic sheathing cable.
It’s also important to mention that modern wiring is insulated with plastic, while knob and tube wire uses rubber. Breakdown of the rubber insulation is a common reason to have your knob and tube wiring replaced.
Degraded and Frayed Knob and Tube
If you have knob and tube wiring in your home, here’s why you need to upgrade your electrical:
- Degradation: Knob and tube wire will eventually break down. If your home has seen multiple homeowners, handymen, and contractors, the mechanical abuse and inevitable wear and tear from decades of service will render a knob and tube system unsafe. Symptoms of old knob and tube electrical systems include cracked or broken tubes, sagging or frayed wires and broken sheathing that exposes live wires.
- Dangerous Combos: Dream Team has inspected several homes that have been wired with old knob and tube and modern wiring. This is extremely dangerous and against the electrical code. Think of it this way, you’re now using different materials that are contracting and expanding at different rates. If left in the wrong hands, altering your knob and tube system can lead to a fire hazard.
- Electrical Demand: With the rise of technology there is a higher electrical demand. Homeowners with knob and tube often overuse and abuse extension cords and power bars. There’s simply not enough power for modern-day living.
- Poor Connections: Problems with knob and tube wire can result from amateurish connections made after original installation.
- Weakness: The rubber insulation on knob and tube can become brittle; this usually happens in high heat areas like receptacles, fixtures and switches.
- Old Technology: Homes with knob and tube wiring will likely have two-prong receptacles. Since there is no ground wire, there is an increased chance of shock and injury, especially around water.
- 60 Amp Service: Knob-and-tube uses a 60 amp service, today it is recommended that homeowners use a 100 amp service/ breaker panel.
