Knob Wiring Upgrades for Older Homes

At Christian Electric Service, we understand the unique challenges and requirements of older homes, especially those with knob-and-tube wiring. This system, a groundbreaking innovation during the era of Thomas Edison and Nikola Tesla, was the backbone of electrical installations from the 1880s to the early 1940s. While durable, knob-and-tube wiring has inherent safety concerns due to its lack of grounding and outdated technology.

The Importance of Wire and Fuse Box Upgrades

Older electrical systems, including knob-and-tube wiring, fuse boxes, and outdated breaker panels, often struggle to meet the demands of modern appliances and technologies. Upgrading these systems is critical to:


  • Enhance Safety: Promptly identifying and addressing risks reduces the chances of electrical hazards like fires and electrocution.
  • Ensure Compatibility: Modernizing your wiring ensures it can support today’s appliances, electronics, and energy-efficient systems.
  • Preserve Property Value: A well-maintained, up-to-code electrical system boosts your home’s appeal and resale value.

With advancements in the electrical industry, it's now easier than ever to live in a safer home that is protected from fire and electrocution.

BX/Greenfield Flexible Steel/Armored Cable (AC Cable)

Well, it's complicated and involves several generations of changes. The "X" in BX stood for experimental, originating in the early 1900s. It became a common wiring method by the 1930s and beyond. This durable armored cable provided added protection for electrical wiring, but over time, safety standards have evolved, revealing limitations in older installations.
