What is knob and tube wiring?

Knob and tube wiring (K&T wiring) is an early method of wiring homes used from the 1880s to the 1930s, but there is still a surprising amount of it about! It is very easy to identify; look for a single wire covered in cloth or rubber, which passes through your joists in its own little porcelain tube. The wire will be fixed to the beam or joist via a 'knob' made of porcelain.

Why you should replace knob and tube wiring

  • No safety grounding conductor
  • Open joints and junctions buried behind walls, ceilings and floors
  • Prone to overloading by using incorrect fuses
  • Danger of overheating and resulting fires in walls, ceilings and floors
  • High risk of decay and rodent damage to the wire casings
  • Insurance companies may not insure homes with K&T wiring
  • Loan companies may not finance a home with K&T wiring

outlets aluminum hazardAluminum wiring

If your house was built during the 1960s and 1970s, it may have aluminum wiring. Aluminum wiring came into fashion during this period when copper prices were high. Aluminum wiring was thicker than copper wiring, yet cheaper and lighter. However, problems arose with compatibility with other systems and appliances, and the different ways aluminum and cooper expand and contract in heat or cold. The result is that aluminum wiring poses a greater fire risk than today's copper equivalents.

When dissimilar metals make contact with one another, corrosion will usually occur. Since aluminum wiring is no longer available for use in your home, any renovations since the aluminum was initially installed will be copper, and any joining of this copper to aluminum could be a hazard waiting to happen. Noticeable symptoms may include flickering lights, and switches or receptacles that are warm to the touch.

At MBH Mechanical & Electrical, we can inspect your existing aluminum wiring and advise on the more cost effective methods to bring your home wiring up to today's safety standards, including replacement of receptacles and switches compatible with aluminum wiring (CO/ALR rated devices).
