Why you need a transfer switch?

The transfer switch will prevent unexpected transmission of high voltages that can cause electrocution. Before the connection of the generator power, your appliances were powered up by electricity. The electricity has high voltages which need to be lowered by a transformer.

However, the transformer can also step up the voltages leading to very high currency. In such an occurrence, if your generator does not have a transfer switch, it will transfer the high energies, which is fatal.

Despite the generator and the electricity having similar AC power, the frequency tends to differ one way or another. If there is a lack of transfer switch, such unequal frequencies can run together, leading to a short circuit. Such eventualities can lead to unexpected fires in your building or damage to your appliances.

It is best to have safety measures to mitigate such risks in your household, office, or any other building.

Lastly, the use of alternative extension cords can lead to back feed from the voltage or power that is running in your utility line. Such connections increase the risk of electrocution.
