What Do Surge Protectors Do

A typical surge protector passes the electrical current along the outlet to number of the devices plugged into the power strip. If the voltage happens to rise above the acceptable level, the protector will divert the extra electricity into the outlets grounding wire.

Do surge protectors really do anything?

Surge protectors offer protection in units called joules. Generally, the more joules the better, as this means the device can handle one large surge, or multiple smaller surges, before your gear is in danger. Over time, the parts inside the protector wear down, reducing its effectiveness.

Why do you need a surge protector?

Surge protectors help extend the lifespan of your electronics. Power strikes and surges put your electronics at risk. Lightning strikes, power outages, grid malfunctions, and several other electrical problems cause spikes. Power surges usually happen because of issues with a power grid.

What appliances need surge protectors?

But bigger or more important items, as well as appliances that require constant power, such as computers, printers, televisions, and refrigerators, should all use surge protectors. Any device that you don’t want to lose in the event of a power surge, or that would be expensive to replace, should be protected.

What should you not plug into a surge protector?

Avoid starting an electrical fire by never plugging these items into a power strip. Large Kitchen Appliances (Refrigerator, Dishwasher, etc.) These appliances are so high-powered that they’ll easily overload a poor, little power strip. Small Kitchen Appliances. Hair Styling Tools. Extension Cords and Other Power Strips.

Should a TV be plugged into a surge protector?

Do you have your PC, television, or other expensive electronics plugged directly into a power outlet? You shouldn’t. You should plug your gadgets into a surge protector, which isn’t necessarily the same thing as a power strip.

Do Iphone Chargers have surge protectors?

It has a small power surge, as do all adapters, but it is not advertised as any surge protection whatsoever. I believe it’s more of a regulator than a protector. I would recommend always using a surge strip or adapter.

Should my refrigerator be on a surge protector?

We do not recommend connecting a refrigerator or freezer to a surge protector. The reason we do not recommend this is explained below: The compressor is sensitive to temperature and current overloads and will shut itself down with a power surge.

Can a power surge damage a fridge?

When there is an increase in voltage from a power surge, it causes an inrush of electrical current within the refrigerator. This surge generates an excessive amount of heat, which can damage multiple parts of the refrigerator. A voltage surge can also damage the refrigerator’s ice maker.

Do modern TVS have built in surge protectors?

Today’s electronic equipment usually has some amount of Transient Voltage Surge Suppression (TVSS) built in.

What’s the difference between a surge protector and a power strip?

A power strip gives you the ability to plug multiple devices into a single wall outlet. A surge protector is a type of power strip which is specifically designed to withstand a power surge and keep your electronics safe.

Do surge protectors work without ground?

Grounding is a critical element required for proper surge protection. In regard to the question about whether surge protectors work on ungrounded outlets, the answer is “no.” Surge protection equipment typically uses components called metal oxide varistors (MOVs) to divert excess current into the ground line.

Can a surge protector catch on fire?

Surge protectors can help to prevent fires if they are in good working shape and used properly. When a faulty or defective unit fails to work correctly, surge protectors can become a fire hazard itself.

Do surge protectors work when turned off?

Answer. When you turn off a surge protector — or suppressor, as some people call them — it’s virtually the same as unplugging it; it will save a small amount of energy and is a little safer in a storm than having the surge protector on.

Do surge protectors work against lightning?

Do surge protectors work against lightning?

Surge protection does offer enhanced protection when lighting strikes. However, surge protectors alone cannot 100% protect your devices. The only way to ensure 100% protection is to unplug everything.

Although items like coffee pots or alarm clocks can feel like the most important items to protect in your home, they do not need surge protectors.

Do surge protectors use a lot of electricity?

The answer? No, surge protectors themselves don’t “drain” energy. But here’s the thing: while surge protectors don’t “drain” energy, the appliances they protect that are hooked into the surge protector DO drain energy-even when they’re not actually in use.

Is turning off a surge protector the same as unplugging?

Turning off surge protector is not the same as unplugging. The main difference between these two actions is that turning off means you are going to turn on the electrical appliance or gadget again and unplugging means you are getting ready to store the electronic device for a long time; say after the holidays.

Are some surge protectors better than others?

A higher joule rating is the best indicator of greater protection. Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000.
