If a switch was on the neutral wire the live wire would still be at the mains potential even when the switch was off. This would cause on en electric shock when one handles any conductor linked to the live wire
If an appliance is plugged in but the switch is OFF, the electrician should always consider the appliance as A. hazardous. C. safe. B. ungrounded. D. de-energized.
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
the safest position for a switch is on the live wire and not on the neutral wire
See Discuss Question below.
It is called Double Insulated because any "hot" wires (= "live" wires in British English) inside the appliance have been made safe by using extra insulation and/or fuses to protect the user from getting a shock if the appliance suffers any damage. That is why it does not need a separate earth or ground wire. Always be sure to switch off the breakers at the main panel before you attempt to do any work on any mains power circuit.
The red wire is typically used for connecting the live or hot wire in an electrical circuit. It helps to safely transmit power to the switch, allowing for control of the connected device or appliance. It is important to follow proper wiring procedures to ensure the switch functions correctly and safely.
If this is about a rebate from the state that you live in for energy efficient appliance purchases you will have to apply with your state tax department and you can probably do it at state web site. If it is from the manufacture of the appliance the dealer that sold the appliance to you should be able to help you with this.
The "can" or metal case of an appliance is supposed to be grounded so if the "live" wire touches it then the breaker or fuse will trip open and remove the power to the wire to prevent the person touching the appliance from being shocked.
So that the live wire is isolated when the fuse blows. If a fuse was placed in the neutral, the equipment would still be live when the fuse blows.
Two different methods, either: 1) Faulty internal wiring is the most common cause. A live cable is somehow electrically connected to appliance. 2) Static build up, can be caused by internal mechanical movement. Note that the appliance may appear charged if a static shock is received, but the charge is not actually received from the appliance, but instead delivered to the appliance from the person.
A fuse should be connected in the live wire, before reaching the appliance.
