What to Search for in a Single Outlet Surge Protector

There are a couple of things to watch on when looking for the best surge protector for your single outlet. We’ve summed up these crucial features listed below:

Joule Rating

The joule rating describes just how much energy your single outlet surge protector can soak up. A greater joule rating equates to better protection.

So how many joules of surge protection do you require? The answer depends upon what you’re securing. Are you safeguarding a PC, single outlet, or perhaps a whole home? Your response will inform you what sort of joule rating you’re looking for.

Here are some rough joule rating guidelines:

  • A system with approximately 1000 joules of surge protection is enough for small electronics.
  • A surge protector with 1000 to 2000 joules will supply adequate protection for office devices and power tools.
  • Consider the greatest joule rating (2000+) for expensive gaming consoles, house theater systems, and any computer system that saves crucial information. Anything that is extremely pricey or irreplaceable.

So consider this as a guideline when choosing your single outlet surge protector.

Warranty

This one’s much easier to explain– the larger the warranty, the better.

Not just for the obvious reason that if something goes wrong, you’ll be able to make a claim, but for the signal that a long warranty suggests about the quality of the single outlet surge protector (or rather, the self-confidence the supplier has for the single outlet surge protector).

If suppliers offered kindly long warranties for single outlet surge protectors that went bust after 2 weeks, they would not be around for long.

So you wish to long for longer warranties and high insurance payments on your single outlet surge protector (from a business that has been around for more than 5 years).

Clamping Voltage

Clamping voltage 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.

For example, a single outlet surge protector may limit a 6,000 V surge so that only 600V is ‘visible’ to the load. Hence here the clamping voltage for this single outlet surge protector is 600V.

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

CHECK the optimum rated voltage of your single outlet before buying a surge protector, so ensure that the clamping voltage of your single outlet surge protection gadget is LOWER than the optimum operating voltage of your single outlet.

In general though, the clamping voltage should be LESS than 700V for a single outlet surge protector.

EMI/RFI Noise Filtering

EMI = Electromagnetic Interference, while RFI = Radio Frequency Interference. Although these terms are utilized interchangeably, they’re technically not the same thing. For the purposes of single outlet surge protection however, we can treat them alike.

Lots of filters – e.g. low pass filters, high pass filters, or band pass filters– only permit specific types of frequencies through, implying a set range of EMI/RFI emissions will be transmitted to the gadget being safeguarded.

This is because certain EMI/RFI emissions will not interfere with the performance frequencies of various electric and electronic devices.

So the objective of EMI/RFI is noise filtering is to eliminate electro-magnetic and radio frequency interference that will hinder the single outlet surge protection.

So look for single outlet surge protectors that have EMI/RFI emissions.

Diagnostic LEDs

It would be best if you had a method to verify that your single outlet surge protector is working– and that’s what diagnostic LEDs are for.

Look for single outlet surge protection that includes diagnostic LED lights that verify power, protection and line fault status at a glance.

Safety Rating

There are a bunch of various security standards by a bunch of various businesses and organizations– so which of these is applicable to single outlet surge protectors?. For the most part, you want to take a look at UL– previously Underwriters Laboratories.

UL is one of several businesses approved to perform safety screening by the U.S. federal 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’re mainly want to be looking at the UL 1449 security requirement.

So make certain your single outlet surge protector verifies to UL 1449.

UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD) – i.e. perfect for single outlet surge protection.
