Knob and Tube Wiring Upgrades in Riverside

Knob and tube wiring was used in North American homes from the 1880s up until the 1940s. While not illegal or inherently dangerous, it’s obsolete and does not meet modern electrical standards. Nor does it support the power requirements of modern appliances. If your Riverside home has knob and tube (K&T) wiring, there are steps you can take to modernize it. At Express Electrical Services, our licensed and trained technicians provide professional knob and tube replacement in Riverside to ensure your electrical system is safe and up to code.

What Is Knob and Tube Wiring?

This old house wiring uses porcelain or ceramic knobs that keep the wiring parallel to wooden frame elements. The tubes help run the wires through the frame and prevent them from touching the wood. Contrary to common belief, knob and tube wiring is not unsafe or dangerous. However, it is designed for service boxes only up to 60 amps and can’t support a 100-amp or higher breaker box.

The Risks of Knob and Tube Wiring

Having knob and tube wiring is a sign your home has an outdated electrical system. The risks come not from this wiring technology being unsafe, but due to the following issues:

  • Lack of Grounding: Knob and tube wiring doesn’t have a ground wire that conducts electricity to a safe place. Modern outlets have three holes to support grounding. A knob and tube system only has two-prong outlets, which increases the risk of shock when using large appliances.
  • Aging Wiring: Since the wiring system may have been installed as early as the late 1800s, its age is a factor in determining its safety. Over time, wiring materials degrade and become unsuited for use in the best of circumstances.
  • Brittle Materials: The varnish and fiber used to insulate K&T wiring tend to deteriorate over time. The stretching and sagging associated with older wiring materials can also create an electrical fire hazard.
  • Poor Insulation: The rubber-insulated cloth insulation around the wiring is a fire hazard. Another hazard is its proximity to building insulation. Foam insulation installed later can prevent heat from properly escaping from the wires.
  • Incorrect Modifications: If a K&T wiring system was spliced to function with modern wiring, a high-power appliance, or a higher-capacity service box, an overload could occur. Regulations have become tighter in recent years. Before then, unlicensed technicians would do electrical work that does not meet modern standards.
  • Insurance Issues: Insurance companies require home inspections. If knob and tube wiring is found, a company may charge a higher premium or refuse to insure your home. That is unless you hire a contractor to perform electrical rewiring.

What to Do If You Need a Knob and Tube Upgrade

If you find K&T wiring in your home, it’s best to leave it alone as the wire casing is likely brittle. While waiting for a replacement, you can use it, but schedule regular inspections by a licensed contractor. Be careful not to overload circuits or use too many appliances at once. You could have ground fault circuit interrupter (GFCI) outlets installed for some protection, but they won’t provide grounding.

Also, avoid splicing the wiring and keep it away from insulation (if it’s touching insulation in your attic or basement, shut off the main breaker and pull the insulation away from the wiring. Wear protective clothing to let heat dissipate from the wires and don’t touch them directly).

Knob and tube removal should be performed during remodeling. Eliminating outdated circuits ensures your home is properly updated. The old wiring system should be replaced in the following situations:

  • Electrical issues are common in your home
  • An inspector finds the system is in bad shape
  • You’re adding or replacing your home insulation
  • Insurance won’t cover your home because of K&T wiring
  • A home improvement project requires an electrical upgrade

Frequently Asked Questions

You’re more likely to find K&T wiring hidden in wall cavities and attics. Therefore, it’s often not easy to find.

It’s not illegal to keep K&T wiring. However, using it to power modern appliances is not recommended. You can install an updated wiring system and leave the K&T alone, but it’s best to consult a professional about knob and tube removal.

Electrical rewiring is a complex job. It entails turning off the power, unplugging appliances and electronics, and removing existing wiring. Professional equipment such as voltmeters, wire/bolt cutters, and other tools are used to remove the wires. Then the technician may remove the knobs; the method used depends on how they’re fastened to the wood framing. Now they can rewire your house, ground it, and install a new electrical panel, receptacles, and fixtures.
