Ultimate Guide to Surge Protectors

Most of us have more devices and appliances than plugs on the wall. That is why you’re likely to find a surge protector behind most people’s HDTV’s and sound systems, as well as under their workstations.

What is a surge protector?

A surge protector is something that protects your appliances and electronic devices from power surges or voltage spikes.

When do you need a surge protector?

All home appliances, devices and electronics are prone to experience power surges. If a power surge goes a bit too high, it can cause a major (or even permanent) damage to your appliances and devices by frying the circuits or melting the plastic.

If you’re using a lot of devices and ever worrying about them getting zapped by a power surge, then you’ll definitely need a surge protector.

How does a surge protector work?

A standard surge protector typically transfers the electrical current along the outlet to several devices that are plugged into the power strip. If the voltage happens to reach a certain point, the surge protector will simply divert the extra electricity with the help of what is basically a pressure-sensitive valve.

With the correct voltage, electricity will flow as though as normally; but with the voltage spike or surge, the surge protector will immediately kick in, redirecting the excess.

What is the difference between a surge and a spike?

When the voltage increase lasts only one or two nanoseconds, it’s called a spike. But when the voltage increase lasts three nanoseconds and above, it’s called a surge. That’s it – that’s the difference. But with even those minuscule nanoseconds – even just billionth of a second – they can cause major or even permanent damage on your electronics especially if the surge goes high enough.

Once you’ve learned the basics about surge protectors – while finally realizing that you’re using more devices than you can imagine – you’ll probably go to an online store and immediately place an order.

But before you get to purchase one, first things first: It is important to know that not all surge protectors are created equal. Some may even put your devices at risk.

It is helpful to read online guides or better, talk to a professional (preferably a qualified electrician) to help you buy the right surge protector for your needs.

1. Know the difference between surge protectors and power strips

First of all, you’ll need to understand that not every power strip is a surge protector.

Power strips are usually cheap, multi-outlet devices that are mere extensions of a wall outlet. They usually have a circuit breaker, or “on/off” switch of some kind, but most of them do not offer real protection from voltage spikes or power surges. While some power strips may offer some level of protection to your devices, most of them are pretty much like outlets, only they’re not fixed onto the wall.

2. Buy the right number of ports

It is good to know that you should buy a surge protector that will exactly serve your power needs. However, don’t assume that every surge protector on the market has six or eight ports the most. Some models have 10 to 12 ports, and they are well-spaced so that you can use them all. Buying the one with the right number of ports ensures that you don’t have to create a (potentially dangerous) “daisy chain” of surge protectors.

3. Consider the device you’re going plug into the surge protector

Think about all the gear you’re going to plug into the surge protector that you’re planning to buy. While you can buy the one that you can afford, you’re going to save some money if you buy a surge protector that’s appropriate for the equipment that will be powered. For example, your HDTV or home entertainment center will need a more robust surge protector than your lamp or smartphone charger.

4. Check for the UL safety seal

Make sure that the surge protector you’re planning to purchase is certified safe by Underwriters Laboratories (UL). To be considered safe, a surge protector must at least meet the 1449 UL standards, which is required for the label “transient voltage surge suppressor”. These specifications will make sure that the surge protector you’re going to buy will actually protect your electronic devices you plug into it, and not put them at risk.

5. Know a surge protector’s joule rating

A surge protector offers protection in amounts called joules. Its joule rating or absorption rating represents how much energy it can absorb before it fails (and your gear will now be in danger). The higher number of joules, the better protection that a surge protector provides to your device.

Surge protectors don’t normally display how many joules of protection are left, but most models feature a LED indicator that lets you know that protection is there. Once the light goes off, it’s an indication that a surge protector should be replaced before it can inflict serious damage to your devices. However, these lights might be ignored or cannot be immediately seen when surge protectors are placed behind a home entertainment system or under a work desk.

No surge protector lasts forever. The parts and components inside it wear down over time, thus reducing its effectiveness. If your current unit has been in use for a number of years, then it’s time to invest on a new surge protector – it will bring you a greater peace of mind.

6. Check the warranty

Some models offer a warranty (up to a certain amount) on the device connected to them if a voltage spike or power surge does get through. Check to see what the warranty covers (and what it doesn’t) and how you can file a warranty claim in the event the device fails to protect.
