Knob-and-tube (K&T) wiring is an electrical wiring method employed in buildings. It was the electrical standard until the 1940s. Though it is now mostly obsolete, this type of wiring is still present in older homes, and it can pose significant safety hazards. As Honolulu, HI’s master electricians, the team at AA Electric share a brief guide about the dangers of K&T wiring, and why you should upgrade your home’s electrical system if yours contains it.

What Are the Dangers of Knob & Tube Wiring?

K&T wiring is not naturally dangerous. It was perfect for powering homes during a time when only a few appliances ran on electricity. The problems they create primarily come from aging equipment or incorrect modifications. Occasionally, a house’s insulation wraps around the wiring, which then creates a fire hazard. Another problem is the lack of a grounding conductor. Without it, the K&T has a higher chance of starting an electrical fire and causing extensive damage to your home.

Why Is Upgrading a Home’s Electricity Important?

Though no new building construction is allowed to install K&T wiring, no specific code states it should be removed entirely from older structures. However, electricians suggest removing as much of the wiring as possible and instead supplementing the existing system with electrical lines dedicated to specific appliances. The process can be costly and time-consuming, and it requires the expertise of qualified electricians, which is why replacing K&T during home remodeling is ideal. If home remodeling isn't an option, you can swap out your electrical systems one room at a time. For some homeowners, home electrical repair may be a headache, but it is the best way to ensure your family and property remain safe.
