But what about a power outage? As you know, this can happen unexpectedly in the area where you are or in your home. However, not many people realize that this can greatly affect their electrical appliances. So they don’t even think about separating them. As a home security measure, but also to protect your devices, it is important to have good reflexes. We explain why.
Power outages: why should electrical appliances be disconnected?
In the event of a power outage or power changes, electrical devices such as television and computer may suffer severe performance damage. In some cases, they can fail, or even cause a short circuit. So, when the power is cut off, your first instinct is to unplug all the appliances you have in the house.
Do the consequences of these disruptions also affect closed devices? In absolute terms, as long as your devices are still plugged in, they may also be damaged.
In addition, although large appliances such as a refrigerator or freezer are more resistant to voltage changes, it is still advisable to unplug them in the event of a power outage.
Can it be connected again right after that?
It is not recommended to connect your household appliances to the mains immediately after restoring the power supply. According to experts, it is necessary to wait at least two minutes after restoring electricity to connect the TV or computer. For some household appliances such as the refrigerator, wait a few more minutes to turn it back on.
So it is better to wait a bit for the power to become stable, so as to avoid possible small cut-offs in a row.
