What is the advantage of main switch?
The major advantage of using a main switch is that it can break the connection of both, the live and the neutral wire at the same time. This protects electrical appliances from accidental damage due to electrical faults.
Why do live wires connect to switches?
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.
What is the function of live wire?
The live wire carries the current to the appliance, while the neutral wire carries it back. The earth wire is for our protection, in case the live wire makes a contact with metal casing of an appliance. When this happens, the current will pass to the earth instead of our body, thus saving us.
Which wire is a fuse connected to?
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.
Why is it dangerous to connect the switch in the neutral wire?
In case of excessive current, it is dangerous to connect the switch in the neutral wire. Even if the fuse blows off due to excessive current and the current in the circuit would no longer be conducted, the appliance will still remain connected to the live wire of a very high potential.
What will happen if a switch is connected in the 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.
What is the importance of neutral wire?
Neutral wires carry currents back to power source to better control and regulate voltage. Its overall purpose is to serve as a path to return energy. Ground wires are electrical paths designed to carry fault currents when a power abnormality occurs.
How do you prevent electric shock?
10 Tips – How to avoid getting shocked when working with electricity at home?
- Never mix water and electricity.
- Pay attention to what your appliances are telling you.
- Install Ground Fault Circuit Interrupters (GFCI).
- Make sure you’re using the right size circuit breakers and fuses.
- Protect kids with outlet covers.
