Updating knob and tube

In the 30's knob and tube was adequate for lights and electric circuits.

Today's air conditioners, dishwashers, and high current devices pull too large a load for knob and tube wiring to operate safely.

Knob and tube should be replaced because the original wiring was designed to carry less electrical current than today's standard wiring.When tearing the lath & plaster off of the back hall of our home, built in 1933, we uncovered every homeowner's worst fear—the unexpected surprise of out-of-date electrical work.Our hallway, which leads to our basement, was laden with knob and tube.Before we could have new drywall put up, we called a local electrician to bid out the project of removing ten instances of knob and tube wiring.The bid came in around 0 and the electrician, with an assistant, spent about six hours updating the wiring.
