Why is this switch put in the live wire?

The switch must be placed in live wire to maintain the body of appliance at zero potential in the switch off position and if the switch is kept in neutral wire, then the body of the appliance to keep the body at infinite potential in the switch on position.

Is switch connected to the live wire?

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.

Does it matter which wires go on light switch?

In the case of a single-pole switch, these wires are interchangeable—it doesn’t make any difference which wire is attached to which screw terminal.

Which wire should the switch be connected to?

Switch should be connected to the neutral wire.

Do you switch live or neutral?

live. A connection from neutral to ground will not likely kill you, but a connection from live to ground stands a decent chance of doing so. And more of the circuit is live than neutral if you switch only the neutral, including any electrical devices on the circuit.

Why is switch connected to live wire and not neutral wire?

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.

What will happen if switch is connected to neutral wire?

If the switches are connected to neutral wire, no current will flow through the appliance and hence it will not operate.

What is Live wire also called?

The live wire is also called hot wire. Live wire is brown or red in colour. This is the wire through which the current enters an appliance.

Quote from Youtube video: So you've got your power coming. In also one new regulation that many areas are following now as well as making sure that. You've got a neutral wire at the switch location at every switch location.

What happens if you hook up a light switch wrong?

But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

Why does my light switch have 4 wires?

Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.
