What Is Knob & Tube Wiring?

Knob and tube wiring, common from the 1880s through the 1940s, uses ceramic knobs to anchor wires and tubes to route wiring through joists. While effective in its era, it lacks grounding and isn’t suited for modern appliances, electronics, or HVAC systems.

In Philadelphia, knob and tube wiring is often discovered during renovations, inspections, or when properties experience frequent electrical issues.

Why Replace Knob & Tube Wiring?

Replacement is recommended for several reasons:

  • Increased electrical demand. Modern appliances and electronics require more power than knob and tube can safely deliver.
  • Safety concerns. Lack of grounding and aging insulation can create fire hazards.
  • Insurance requirements. Many insurers decline coverage for properties with active knob and tube wiring.
  • Property value. Buyers are often hesitant to purchase homes with outdated electrical systems.

Replacing knob and tube wiring provides a safer, more reliable foundation for your property’s electrical system.

Signs Your Property May Still Have Outdated Wiring

Look for:

  • Porcelain knobs or tubes visible in basements, attics, or crawl spaces
  • Two-prong outlets without grounding
  • Frequent blown fuses or tripped breakers
  • Brittle, cracked, or fabric-covered wiring

A licensed electrician from Jim & Sons Electric can inspect and recommend the right upgrades.
