How does Mainline Stabilizer protect my home appliances?

This stabilizer is installed between your main power supply and your home appliances. This product is designed to smoothen out any voltage fluctuations coming from the main power supply and provide a constant supply to your devices.

In simple words, if the input voltage coming at this point in time is higher then when your appliances can handle, your stabilizer will reduce it to an acceptable level. Similarly, if the input voltage is low, it amplifies it.

This way the mainline voltage stabilizer provide a constant supply of electricity within your device’s operating range. This helps prevent any unwanted damage due to overloading and increases the life of your home appliances.


How many appliances can I run on my mainline stabilizer?

This depends on the wattage of the devices you use. You should add up the peak power requirements of all appliance in your household to figure out which stabilizer you should be buying.

Normally, people with multiple phases of electricity in their homes, use one phase dedicated for all heavy appliances like Air conditioners, Washing machines (Especially if you use heated water to wash your clothes) etc.

You can use a mainline stabilizer on the second phase which will run fans, lights, televisions and other smaller appliances.


Do I need to buy separate stabilizers for my appliance even if I have a mainline stabilizer?

It is highly likely that you will need a separate stabilizer for heavy appliances like Air conditioners. If you are not sure, do consult an experienced electrician to suggest you the right combination.
