The position of switches and fuses 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. If the switch or fuse is placed in the neutral wire, the electrical appliance is still connected to the high voltage live wire even when the switch is open, or the fuse is blown. This could cause the user to get an electric shock if they touched the inside of the appliance. A switch or a fuse is always connected to the live wire. Double Insulation Appliances encased in an insulating plastic case or body, such as hair dryers, mobile phone chargers and hand whisks do not need an Earth wire. Such appliance are designed so that there are two levels of insulating material between the electrical parts of the appliance and any parts on the outside that can be touched. These two layers are normally the insulating plastic case and the insulated cable carrying the live and neutral wires. A metal attachment, such as a whisk blade, is fitted into a plastic case so that it does not make direct contact with the internal electrical parts. Even though the device contains a live wire at mains voltage, there are two layers of plastic separating the user from this live wire. The symbol for double insulation on an appliance is:

The live wire of domestic circuits is usually red and is at high voltage. The neutral wire is black and has voltage close to that of the ground. The potential difference between these two wires in India is about 220 V. The earth or ground wire provides safety against faults and current leaks. Earth pin is longer to ensure earth connection happens first while connecting and last while disconnecting any devices. Created by Mahesh Shenoy. Hi ! The neutral wire just has it's voltage the same of Earth , but it can't be connected to ground as voltages of ground and wire will be same the electricity won't flow (As their potential difference is equal ) . Making it simpler it's like connecting two tanks having same amount of water in same height and expecting the water to move from one to the another (which isn't possible) here's a seemingly boring plug and a plug point something that we see every day right but here's an interesting question if you looked at your plug carefully you will see that the top of the top pin is usually longer and thicker compared to the other two pins why do you think that is the case turns out that this can save us from deadly shocks but how you may be wondering how can a little feature like making one pin longer can save us from shocks well to answer that question we need to explore what are the different wires that come to your plug point and what each wire does so that's what we will do in this video we'll explore these three wires and then hopefully ...

How To Add A Neutral Wire To An Existing Light Switch Electrical work is intimidating even if you have experience, and that is especially true when it comes to adding a neutral wire to a light switch. Luckily, you can add a neutral wire either to the switch box or simply extend your old wires to the new box. Whether you add a wire or extend one, let’s take a look at how you can add an existing neutral wire to an existing light switch. Adding a neutral wire can be a little daunting, especially if you’re dealing with a light switch that you’ve had for years. A neutral wire makes smart home creation easier and also better completes your electrical circuits. If you are adding a smart home switch box to your place, chances are that you might need to add a neutral wire to your current setup. You can either add a new neutral wire to your switch box, or you can choose to extend your older neutral wires to the newer switch box. Both projects will require you to call an electrician due to the sheer complexity of it. However, there are some workarounds and it’s good to know the general steps that will be done. This is great for old school inventions, but not if you want to have a smart outlet. Smart outlets need to have a constant stream of power. If they’re switched off, they can’t be programmed. A neutral wire is meant to carry voltage back to the power source, which means that your switches won’t entirely cut off from electricity. Do You Need A Neutral Wire? In many cases, outlets...

In redoing my main level I have misplaced my electrical diagram showing what was there before I started (so annoying!). Now I am unsure if my new solution is safe or not. I have seen diagrams which confirm, but would greatly appreciate an expert helping me out. So here's what was there before (see my horrible diagram attached): - power to the fixture - three wire to a switch (not a two way or three way switch) - power continues to an outlet I want to remove the outlet part. But this makes the three wire neutral "stranded". I have tested the wire and there is nothing there (perhaps that is obvious to most!). The second picture attached shows the current setup. So the question is: Is this safe? If the neutral was for an outlet that you're removing from the system, then so long as other outlets in the circuit have a properly grounded neutral wire, everything should be all set. Be sure to cap off the stranded neutral wire. Keep in mind that wiring isn't always what you expect, so verify that each wire is indeed hot or neutral as expected. Code in the US dictates that black is hot, white is neutral and bare copper is ground. Neutral: The white wire is called the neutral wire. It provides the return path for the current provided by the hot wire. The neutral wire is connected to an earth ground. See this guide for more info You should think about editing your answer so that it is more accurate and less misleading. As it stands now there is the direct implication that the neutral ...

Most of the common types of switches come in different styles, such as toggle, rocker, slider, or push-button. The style usually does not affect the switch function and Below, you'll learn about eight common types of wall switches and what they're best for. The Spruce / Claire Cohen • Best for: Controlling a light fixture, appliance, or outlet from a single wall location A Examined closely, you'll notice that a new single-pole switch has two brass-colored screw terminals attached to the body of the switch, plus a green screw that is connected to the metal strap. In normal use, this type of switch is used to control the flow of current through "hot" wires in the circuit (usually black wires). With single-pole switch wiring, each of the brass-colored screw terminals is attached to a hot wire, and there is generally no neutral wire connection at all. The circuit's grounding wire (usually a bare copper wire) is attached to the green grounding screw on the switch. As a general rule, neutral (usually white) wires are not connected to switc...
