What is Knob and Tube Wiring?
Knob and tube wiring was one of the earliest standardized electrical systems used in homes and buildings between the 1880s and 1930s. This system featured single copper conductors wrapped in cloth insulation, routed through ceramic tubes and supported by porcelain knobs, hence the name “knob and tube.”

At the time, it was considered a major advancement in electrical safety. However, it was designed for a much lower electrical load than today’s homes require and lacks essential modern safety features, most notably, a ground wire.

Why Knob and Tube Wiring is Unsafe and Outdated

Today, knob and tube wiring is considered obsolete and a significant fire hazard. Common risks include:

• No ground wire, making it incompatible with modern appliances

• Deteriorated insulation, especially around light fixtures

• Increased risk of fire due to exposed conductors and lack of junction boxes

• Vulnerability to damage from rodents, renovations, or accidental contact

• Insurance concerns—many providers deny coverage or increase premiums for homes with this wiring

If you’re buying, selling, or living in a home built before the 1940s, this wiring is a red flag during inspections and often a deal-breaker unless replaced.
