I want to know, which type and size of wire we use for different household appliances in a home ?for e.g: if we want to connect a full size refrigerator/deep freezer/air-conditioner then which type and size of electrical wire we use ?if we have an electrical switch board that has 6 switches and 2 sockets then what type size of wire should be used so that there would be good connection and to avoid burning or heating of the wire and hence the appliance ?thanks a lot for your co-operation
The average home uses # 12 wire. Older knob and tube homes use # 14. If the refrigerator is on its own circuit, # 14 is plenty. Lok at the appliance rating: Watts Volts X amps. A 1200 watt appliance at 120 volts would be 10 amps. A # 14 wire is fused at 15 amps. A # 12 wire is fused at 20 amps.
House wiring must conform to wiring codes. Some places require the work be done by or at least signed off by a licensed electrician. Unless you follow your local codes you run the risk of fire, or even death in wiring near water. What's more, you will not be covered by insurance and you will be held personally responsible. There are too many opportunities for wrong answers on the internet. Please consult a licensed electrician.
