When selecting a surge protector for your refrigerator, it's essential to choose one with an appropriate power rating to handle the starting and running currents of the refrigerator's compressor. Refrigerators typically have a higher startup or surge current, which can be several times higher than their normal running current.

To determine the surge protector size you need for your refrigerator, follow these steps:

  1. Find the refrigerator's wattage or amperage: Check the refrigerator's nameplate or user manual for the power rating. You'll be looking for either the wattage (W) or amperage (A) rating. If the information is given in amps, multiply the amperage by the voltage (typically 120V in the USA) to convert it to watts.

  2. Calculate the surge protection capacity: Since refrigerators experience a surge when they start up, it's recommended to get a surge protector that can handle at least three times the wattage or amperage of the refrigerator's running current. This will ensure the surge protector can handle the initial power surge without tripping or being damaged.

  3. Choose an appropriate surge protector: Look for a surge protector with a power rating equal to or greater than the calculated surge protection capacity. For example, if your refrigerator has a running current of 5 amps (600 watts) at 120 volts, then you should choose a surge protector that can handle at least 15 amps (1,800 watts) or more.

  4. Consider additional features: Some surge protectors come with additional features like multiple outlets, EMI/RFI noise filtering, and indicator lights. These features can provide extra value and protection for other devices connected to the same surge protector.

It's important to note that not all surge protectors are designed to handle the high surge currents of appliances like refrigerators. Look for surge protectors specifically labeled for use with appliances or refrigerators to ensure they are suitable for this purpose.

Additionally, consider investing in a surge protector from a reputable brand that offers a warranty and guarantees protection against power surges. This way, you can have peace of mind knowing your refrigerator is well-protected from potential electrical hazards.
