Fuse-wires are used, at the mains as well as at the device plugs to avoid damage to wiring as well as the electrical devices, in case of current outages.  

Similarly Voltage Stabilizers with cut-off are used to avoid voltage outages that cause damage to electrical/electronic appliances. 

Now that the safety of the wiring and the devices have been taken care of, human safety is left for discussion.

Historically human safety has been more on the defense, whereby using rubber gloves, switching off mains, covering electrical lines, devices with insulating materials like plastics/ceramics have been adopted. 

However these do not prevent accidents involving electric shocks and Trip switches have become indispensable in electrical wiring for ensuring human safety.

Trip-switches detect load leakage currents and break-off the electrical connection.   However if the wiring is not done properly you will have tripping and you will have a tough time in identifying the source.   So the advise is to master your electrical wiring plan and use trip switches at strategic electrical branches, so that you can fix that particular line easily.

Now there are trip switches which break even before a person receives a shock.   In order to install this, one has to do the electrical wiring with a trained electrician, or it may never let you operate a gadget.

Though you may have a nice home, comfort today is determined by electricity.  Hope this article will prompt you to know more about electrical wiring with the experts and accomplish Human/Device/Wiring safety for your home.
