What to Search for in a Single Outlet Surge Protector

Buying the best single-outlet surge protector means paying attention to a couple of features. Let’s see what you need to know before spending your money:

Joule Rating

Usually, bigger does not necessarily mean better. However, when speaking of Joule energy rating, a higher value equals better and longer protection for your electronics.

So how many Joules of surge suppression do you need? Depending on what you are aiming to secure, the answer varies.

Here are some rough Joule rating guidelines:

  • A system with less than 1000 Joules energy rating is enough for small electronics.
  • A surge protector with 1000 to 2000 Joules surge suppression supplies enough protection for office devices and power tools.
  • Expensive large electronics will require a higher Joule energy rating, something over 2000 Joules.

Try to remember the values mentioned above when you decide to buy a single-outlet surge protector.

Warranty

A more extended warranty period means a more reliable single-outlet surge protector.

Apart from being able to make a claim if something goes wrong, an extended warranty points out the self-confidence of the manufacturer. Those suppliers who offer long warranties for poorly made single-outlet surge protectors will not resist too much on the market.

We recommend you to check surge protectors from a business that has been around for more than five years. More extended warranties and high insurance guarantees are also desirable.

Voltage Protection Rating

Also known as clamping voltage, this value describes the optimum quantity of voltage that can pass a surge protector before it limits further voltage from passing to the gadget it is attempting to safeguard.

If the voltage protection rating is too high, then the surge protector will enable excessive voltage to pass to your single outlet (and will break it).

CHECK the optimum rated voltage of your outlet before buying a surge protector. Make sure that the clamping voltage of your single outlet surge protection device is LOWER than the optimum operating voltage of your socket.

The lowest UL rating for voltage protection is 330V.

EMI/RFI Noise Filtering Capability

EMI stands for Electromagnetic Interference, and RFI means Radio Frequency Interference. For example, power filtration is designed to reduce EMI and RFI on power lines for better sound and picture quality on entertainment devices such as home theatres or television.

Many filters like low pass filtershigh pass filters, or band pass filters only allow specific types of frequencies, implying a set range of EMI/RFI emissions will be transmitted to the electronic being protected.

So the objective of power filtration is to eliminate electromagnetic and radio frequency interference that will hinder the single outlet surge protection.

Remember that single outlet surge protectors with higher EMI/RFI noise reduction capabilities (measured in dB) provide better filtering.

Diagnostic LEDs

It would be best if you had a method to verify that your single outlet surge protector is working. This is where diagnostic LEDs intervene.

Look for single outlet surge protection that includes both protection indicator light and a ground indicator LED. The first will indicate when the surge protector needs replacing, while the other shows that the device is connected to a properly grounded outlet.

Safety Rating

There are various security standards by multiple businesses and organizations. You may be wondering which of these is applicable to single outlet surge protectors?.

The most important is the UL, previously Underwriters Laboratories.

UL is one of several businesses approved to perform safety screening by the U.S. national firm Occupational Safety and Health Administration (OSHA). OSHA has a list of approved testing labs, which are acknowledged as Nationally Recognized Testing Laboratories.

Even within UL, though, there are a lot of security requirements that could use. For appropriate single outlet surge protection, you are interested in the UL 1449 safety standard.

The best single-outlet surge protectors conform with UL 1449 safety standards.
