How many joules should my surge protector have?
Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more. Response time – Surge protectors don’t kick in immediately; there is a very slight delay as they respond to the power surge.
How many joules should a surge protector have for a TV?
Recommendations. Electronic accessories manufacturer Belkin recommends its 1,411 joule model for most TV sets, or its 2,444 joule unit for projection televisions. ReviewSurgeProtector.com similarly advocates a minimum level of 1,500 joules for TVs.
Can you have too many joules in a surge protector?
Clamping voltage is the amount of voltage it takes to gets the surge protection to kick in. The lower the voltage, the better the protection. It doesn’t matter how many joules your surge protector has. You shouldn’t buy anything with a higher voltage than this.
What should you never plug into a surge protector?
Never use power strips or surge protectors for high-power capacity items such as, space heaters, dehumidifiers, or other high capacity appliances. Plug them directly into a wall outlet.
What does 1500 joules mean?
Joules are measurement of energy. For example, 1500 joules is like leaving a 1500 watt hair dryer on for one second. If your electronics are sensitive to energy surges, you will want a surge protector with a high joules rating and a low clamping voltage.
How many joules is a computer?
Small electronics (like lamps, radios, and battery chargers) are fine with joule ratings under 1000. But for computer or home theater equipment, you’ll definitely want to consider surge protectors with joule ratings of 2500 or more.
How many joules is a lightning strike?
one billion
With an average bolt of lightning striking from cloud to ground containing roughly one billion (1,000,000,000) joules of energy, that is a lot of power in every lightning bolt!
What does joules mean in surge protector?
A Joule rating tells you how much energy the surge protector can absorb and thus safely protect the equipment plugged in to it. The higher the joule rating, the more robust the surge protector and the longer it will likely protect.
What appliances need surge protectors?
The most important products to plug into a surge protector are expensive electronic devices with microprocessors. Desktop computers, laptops, televisions, gaming systems, and charging phones should all be plugged into a surge protector, so they aren’t damaged in a storm.

What Does a surge protector 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.
