It stopped being used because it became too expensive with 3 wiring systems. If the plugs in a home have only two holes in them, the wiring is probably knob and tube. It uses copper wire.
- Aluminum Wiring- Just as safe as copper wire if installed properly. The problem with aluminum is that is oxidizes and expands more than copper resulting in the joints between the wires to overheat and seperate forming a gap.
- Copper Wiring- avaliable in a wide variety of sizes to accommadate different electrical loads. These systems can be very safe.
