These days, it’s hard to imagine life without electricity and frankly speaking, no home is designed with enough wall sockets for all the electrical appliances. That’s the reason why we need extension cords to expand the capacity of our home’s electrical system, turning one plug into six or more.

However, there are some very important electrical safety rules when you extension cords that we still innocently violate every day. Let’s check them out!

1. Plug one extension cord into another

Sometimes an extension cord isn’t long enough, or we need more plugs, so we often “chain” several extension cords together by plugging one into another. In short – never do it!

This is not just a violation of safety rules in theory, but it can cause one or more outlets to fail or even catch fire in practice.

Not all extension cords are specifically designed for outdoor use, unless their packaging clearly states that they are weather and water resistant. If you have a very common extension cord, keep it indoors and buy a more rugged one that you can safely use.

3. Weak sockets but full of  loads

Every extension socket has a load limit. It means that it can only handle a certain amount of power at any one time. When an extension socket is overloaded, it can melt, damaging your home and surrounding appliances as well as creating a fire hazard.
