How do you de energize an electrical circit?
De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.
What is the definition of main switch?
Type your answer here... main switch is difine as the switch which opparate whole power throw the house.
What is the function of main switch?
The main switch fuse box is there to help prevent electrical fires. If you overload a circuit, and it tries to draw more current than the wire is supposed to have, it will pop the fuse, causing an open circuit, and electricity stops flowing. The main switch allows you to disconnect all electricity coming into the home. Otherwise, the current would heat the wire to the point where it would burn/melt the insulation, then the bare wires would start the house on fire. Not fun if left unattended.
What has replaced fuses in the main fuse box in a house?
Resettable circuit breakers.
Why main switch use in the rest of the circuits in the house?
A main switch controls the entry of power into the property. Inside the property there may be several circuits that are individually switched

Why is the main switch connected in series together with the rest of the circuits in the house?
It is connected so that it can disconnect the entire power grid in the house with one switch. This switch is usually integrated into a circuit breaker. No matter how one looks at it, this switch must be made to withstand (and be able to switch) great currents (in excess of 16A) at relatively high voltages (120V/230V). Special care must be taken during the design phase, as the switch will most likely have to suffer severe arcing as well as heating, during normal operation.

What are the main parts of a household circuit?
One main part of any household branch circuit is its circuit breaker. It is designed to protect the electrical circuit from damage caused by current overloads or short circuits. It is designed to disconnect the electrical flow within a few milliseconds if it detects certain electrical faults. Then, to be able to provide power to the appliances and lights in the house, there must be fixed outlets and socket outlets supplied by the various branch circuits. Nothing can be provided with electrical power unless there is a main breaker panel to contain all the separate circuit breakers and also to provide the house with a main power on-off switch.

Where in the circuit do you insert the switch?
i assume main switch in that case at the mains input.

What is the difference between a fuse and circuit?
a fuse main purpose is to quickly disconnect a short circuit. when the current passing through it exceed its rated value
Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?
Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.
Why was a switch made?
A switches main purposes is to stop the current flow in a closed circuit.
What is the main parts of the house hold circuits and simple circuits?
household circuit comprises of main swith,circuit breakers,wires and control switches.
