What is the population of Karachi Electric Supply Company?
How do you install a doorbell with four wires both having black and red wires?
It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.
Asked in Home Electricity
Why there is always a neutral wire in the supply of electricity to home?
For any electricity supply there has to be a pair of wires to carry the electric current. One of the wires is connected to earth at the transformer where the power comes from. That one is called the neutral. They can't both be grounded so only one of them is, and that prevents a buildup of static electricity.
