How do you wire two switches and lights with the same power?

If you’ve mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail.

How do you wire a black and white light switch?

You connect the black wires in the electrical box to the switch terminals, and the white wires to each other. The switch also has a green terminal for the ground wires, which usually are bare.

Should a switch be on the live or neutral wire?

The purpose of a switch or a fuse is to break or connect an electric circuit, but they must be correctly connected in the home. A switch or a fuse in an electrical circuit is always connected to the live wire so that the socket or appliance is not live when switched off.

In which wire the switches can be connected?

A switch must be connected in live wire. Explanation: A switch must be connected in live wire, so that when it is in ‘off’ position, the circuit is incomplete and no current reaches the appliance through the live wire.

How are light switches wired?

The white wire from the service panel is wired to one side of the light. The black wire is spliced to a black wire in a cable that runs to the switch. That cable’s white wire is also connected to the switch and runs back to and is connected to the light.

What will happen if switch is connected in neutral wire?

If switch is connected in the neutral wire, an electric appliance, e.g., an electric iron will remain connected to the live wire even when the switch is off and so if any one happens to touch the appliances; he of she will get a shock which is sometimes fatal.

Why the fuse and switch must be on live wire?

Once the fuse has melted, the circuit is broken and no more current flows through the device. The fuse or circuit breaker must be connected in the live wire side of a domestic circuit to ensure that it keeps high voltage from reaching the user, or surroundings, if a fault develops.

Why are switches connected to the neutral wire and not the live wire?

Because ‘earth’ is always connected there is nothing to be gained by switching off neutral, except that this would break the load connection and stop the powered device. Switching the ‘live’ wire isolates the device from the power source. Not only does it stop the device it removes the power connection.

Where do you connect the live wire on a switch?

The switch should always be connected to the live wire, so that when it is ‘off’ no current flow through the appliance as the circuit is open. If the switch is connected to the neutral wire, then even in the ‘off’ position the appliance remains connected to high potential through the live wire.
