How to use an electrical power strip without risk?

The power strip is a very practical accessory for anyone who has several electronic devices to plug in.

Indeed, it allows you to connect several devices to a single electrical outlet, thus avoiding overloading the wall sockets.

However, misused, a power strip can be dangerous.

In this article, we will explain how to use a power strip safely.

What is an electrical power strip?

A power strip is an electrical power supply that allows the connection of several devices to a single electrical outlet.

It is usually equipped with several female sockets and a power cable that plugs into a wall outlet.

A power strip can take from 2 to 10 sockets depending on the model.

What are the different types of multiple sockets?

There are different types of power strips, each with its own features and specifications.

The most common types are:

• Power strips with switch: they save energy by cutting off the power supply to all connected equipment when you don't need it.

• Power strips with surge protector: they protect your electrical equipment against electrical surges, which can damage your electronic equipment.

• Power strips with USB ports: these allow you to charge your electronic devices, such as smartphones and tablets.

• Power strips made in a waterproof monobloc for outdoor use.

Some also have an indicator light to indicate operation.

What are the risks of using a power strip?

The use of a power strip can present certain risks if used incorrectly.

Electrical overload is the first danger.

When you plug too many devices (especially those that are too powerful) into a single power strip, this can lead to electrical overload, overheating and can trip the electrical panel.

The risk is then to cause an electrical failure and even fires.

The power strip's power cables can become damaged over time, particularly due to twisting, stretching or wear.

If the wires are damaged, it can lead to short circuits, sparks and even fires.

The final risk is electrocution.

A damaged plug can cause electrocution during handling.

It can also cause a short circuit, or damage the machines connected to it by causing an overvoltage.

How to use a power strip correctly?

Here are some tips for using a power strip correctly and avoiding risks:

• Avoid plugging too many devices into one outlet.

• Be sure to comply with the reference power standards and not to exceed the electrical capacity of the power strip.

  The maximum number of watts is generally indicated on the label of the power strips.

• Never connect two power strips in cascade.

• Use quality and certified power strips (NF standard).

  Make sure to buy them from reliable sellers.

• Avoid placing the power strip under carpet or furniture, as this may cause overheating.

• Avoid touching the power strip with wet hands or bare feet, as this may cause electric shock.

• Regularly check the power cables of the power strip and replace them if they are damaged.

• Avoid plugging high-powered electrical equipment into the same outlet, such as heaters, air conditioners or major appliances: this can cause overheating and electrical surges.

• Finally, avoid using an extension cord on your power strip: this increases the risk of overheating and fire.

In conclusion, an electrical power strip is very practical, but must be used correctly to avoid the risks associated with its use.

By following these tips, you can use your power strip safely and avoid electrical problems.
