Why should you install a home voltage protector?


Would you live in a house with No MCB ? Would you feel safe to live in that house?

Whenever a building is designed, all safety factors are taken into consideration. From electrical installation point of view , the safety factors to be considered are

  1. Over current
  2. Spikes
  3. Over voltage

All of them have to considered from worst case scenario basis, if not then it can cause fires and loss of property, worse.. loss of life.

Generally short circuit is taken care with help of MCBs/ fuse. While MCB/fuse can handle overload issues , short circuit, which is the worst case scenario is also taken care

Lightning protection

Lightning protection is generally taken care in high rise building , but the measure taken are incomplete and only from structural integrity point of view as lightning strike on a building will result in structural damage. Lightning rod is installed on top of building and connected to an earthing pit so that lightning pulse can be directed to the ground with out causing damage to building

As the lightning strikes the rod and passes to ground the wire carrying the lightning pulse to ground with gets magnetized. If there is any utility wire which is in the magnetic field of wire carrying lightning pulse, the charge can transferred to the utility cable, this is how normally electronic equipment get damaged due to lightning.

Spike protection

Every on off action of any electrical or electronic device will create a spike. This is how spike is generated inside your house. Dont believe us? Do a small experiment.

  1. Go to your bath room and switch on the light bulb and now switch on the geyser
  2. you will notice that the light from the bulb flickers or goes dim.
  3. now switch off the geyser , you will see that light goes bright again.
  4. Congratulation!!! You have created voltage fluctuation in your house!!!

The geyser is generally 3000-4000 Watts and it causes voltage fluctuation during its on -off operation. Now imagine the same for other equipment in your home. viz. TV, refrigerator, AC.

So the bottomline is that the spikes are always there in your house. Its not a question of if but when it will damage your electronic items.

Do you have any safeguards against spikes in your home? now that you know that spike are also always there, does it not scare you?

Over voltage protection

The MCBs and fuses are current sensing protection. In a Fuse when the current increases, wire melts in fuse to disconnect the circuit. In an MCB there is bimetallic strip inside it bends due to heat causing it MCB to release contact and make it trip.

If the voltage changes from 230V to 280-290 V, it has not effect on the current and as a result the MCB/ fuse do not react. Your equipment can get damaged by high voltage and MCB / fuse will not react

This brings us back to question ” Are you really protected in your home from electrical problems?”

This is the reason why you should install a home voltage protector.
