Knob & Tube Wiring

This type of wiring was used in buildings in North America from about 1880 to the 1930s. It consists of single-insulated copper wires run within walls or ceilings, passing through joists and stud drill-holes through protective porcelain insulating tubes, and supported along their length on nailed-down porcelain knob insulators. Due to the age of this wiring, if there are an live wires in your home or building, the should be replaced immediately. This type of wiring is also known to cause problems with squirrels and other rodents damaging the wires.

BX Wiring

BX wiring are bundles of insulated wires sheathed in a flexible and protective metallic sheath.  
BX or Type AC is one of the earliest types of electrical cable made for both residential and commercial uses in the early part of the 20th century.  "BX" is the older term for this type of cable. It’s assumed that the name originated from the Bronx, NY since the first BX cable was made there.

BX cable is still used today in both residential and building applications. It is especially used when the wiring is exposed and not protected by interior walls i.e. workshops, commercial buildings, etc.

If the protective insulation is nicked or cut, the wiring should be replaced.  Also, if the wires within show degrading of their rubber insulation, these wires should also be replaced.
