Factors to Check Before Purchasing the Best Single Outlet Surge Protector

Safety Alarm

Nowadays, most compact single appliance surge protectors don’t have any safety alarm. Instead, they only feature indicators or signal bulbs that show the status of protectors and the current.

So if you can buy a protector with a safety alarm that notifies about getting grounded or turned off, that would be a plus point.

Size and Weight

When discussing single outlet protectors, the perfect weight range can be between 4 to 10 ounces. But the weight can increase if the surge protector has dual or triple outlets.

Clamping Voltage

The less clamping voltage is, the better a surge protector would be. However, according to our experience using tons of products, 400 clamping voltage surge protectors do the job very well.

Quality protectors regulate conduct RFI via filtering the frequency to a decent level. The right amount of filtering depends on which type of home appliance you’re using. For example, refrigerator surge protectors have a higher filtering rate than regular plug surge protectors.

In that case, it should at least show overflow, underflow, active, and grounded signals with separate LED bulbs. It helps the homeowner to get the perfect reading of the house’s power system.

Safety Rating

These days, power surge protectors with a safety rating around 1000 to 1500 Joule is considered perfect. Even a refrigerator surge protector with more than 1200 Joule safety rating is a good one to pick for optimal maintenance.
