Knob and Tube Wiring Was the Standard Between 1880 and 1930

One of the earliest commonly used standard wiring methods that is still in limited use today is referred to as knob and tube wiring dating back to the early 1880’s to 1930.

 

Its name comes from the use of ceramic knobs used to hold wires in position while the ceramic tubes acted as protective cases for wires running through the floor and wall studs.

 

If you are living in an older home in the Black Diamond area with this knob and tube wiring method there are associated safety issues with which you should be familiar:

  • Degrading rubber insulation exposing wires to moisture increasing the chance of fire
  • Load demand limitations
  • Two-stranded wiring with no provision of ground wire
  • Fire hazard with more current flowing through wire than it was designed to handle

Since most homes built during that time period likely have this type of electrical wiring that is now found to be dangerous, uninsurable and impractical in today’s electronic age, we recommend calling on our licensed electricians to examine the system in your Black Diamond home for visible hazards and to recommend appropriate upgrading.

 

Why Replace Knob and Tube Electrical Wiring in Black Diamond Homes?

Replacing knob and tube wiring likely occurred in the 1930’s with the growing popularity and availability of non-metallic and armored cable systems for residential homes.

 

These are a few reasons to consider knob and tube wiring replacement in your home:

  • Fire hazards where splices with red hot connections could ignite cellulose insulation
  • Lack of a ground conductor
  • Switches placed on the neutral wire turning off the circuit but not the current
  • Improper alterations or unsafe splicing creating a potential safety hazard
  • Degradation of wire insulation by heat and critters
  • Refusal by insurance companies to write a policy
  • Most installations restricted to 60-amp service

While some still consider this wiring method superior to current wiring practices when originally and correctly installed, these major problems and the fact that it is uninsurable are reasons to call us for replacement wiring of your Black Diamond home.
