What came after knob and Tube wiring?

A look behind your outlets



Why is this bad wiring?

1. All new electrical circuit are grounded for safety. 
2. Many pieces of electronics need a ground to work reliably and safely 
3. The insulation around the the wires is cloth that gets weaker with age.
4. The wire an not capped with wire connectors. They are only taped.
5.Flammable dirt an dust builds up by the electrical connections in the junction boxes. All they need is a spark.
6. Circuits often get extended with new wires to carry more then they were originally intended to.
