If several devices are plugged into a single power strip, the power of these devices adds up.

There is therefore a real risk of electrical overload.

As a result, the wire before the socket can start to heat up.

And unfortunately, it can then catch fire.

A long reference writing about a power strip

– Even if it is very practical to plug in the electric plates, the garland of the fir tree, the raclette grill and a lamp at the same time… on an extension cord with a power strip. Don’t! It’s dangerous. Do not connect them with each other, in a row. You just don’t have to extend a power strip by plugging it into an extension cord.

– Next, avoid plugging too many power strips into the wall outlets at the same time. Your electrical installation may not be designed for this. And you risk breaking everything!

– Finally, in all cases, it is formally not recommended to connect powerful devices to a power strip. Fridge, plates and especially radiators… Forget! So, you wonder what good is a power strip if you can’t plug anything into it? It’s simple.

Reserve the use of power strips for small devices such as mobile chargers, a coffee maker, a screen, etc.

Electrician’s word!

Don’t forget that according to the National Observatory for Electrical Safety, there are 240,000 declarations of home fires in France with insurance companies.

And 20 to 35% of these fires have a electrical source. So be very careful.
