What joule rating do i need

Generally, you'll want to look for point-of-use surge protectors rated for at least 200-400 joules, but 600+ joules is even better. Surge protectors rated for 1000+ joules are optimal for protecting electrical devices like lamps, small kitchen appliances, digital clocks, etc.

How many joules do I need to protect my TV?

A common question we hear is, how many Joules do I need to protect my TV? For HDTVs it is best to consider the highest Joule ratings – at least 2000. Austere recommends the V Series Power (3000 Joules) for 4K HDTVs less than $1,500 and VII Series Power (4000 Joules) for 4K HDTVs more than $1,500 and 8K HDTVs.

What is a good joule rating?

1,000 to 2,000 joules: For appliances that you want to keep safe and working properly, look for a joule rating in the 1,000 to 2,000 range or higher. Cellphones, tablets, routers and laptops should be protected in this range, but it would still be safer to find a higher joule rating.

Is it better to have higher or lower joules?

Joules are the key to surge protection. With surge protection, it's about joules. The joule rating of your surge protector determines how much energy your surge protector can absorb. The higher the joule rating, the greater the protection.

How do I choose a joule for my surge protector?

Energy absorption/dissipation: This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. 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.

How many joules is a lightning strike?

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!

Is 1000 joules enough for a TV?

The absolute minimum joule rating that I would suggest would be 2,000 joules. However, for anything really valuable, I would highly suggest 3,000 joules or more.

Is 600 joules enough for TV?

A higher number indicates greater protection. 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.

How many joules are needed to protect a refrigerator?

Ideally, a surge protector which provides a 1000 to 2000 joule rating will provide the required protection. Yet, some high-power surge protectors also provide a joule rating of more than 2000. For example, a home refrigerator has 200 W of average power multiplying it by five, we get 1000W.

How many joules do I need to protect my RV?

When it comes to a minimum, you can pretty much write off any surge protector with less than 1000 joules. Most RVs require somewhere between 1000 and 2000 joules to protect internal appliances.

What size whole house surge protector do I need?

Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Protection for an average house with 200-amp service will run about $500—including a couple of hours of an electrician's labor.

How do I choose a surge protective device?

Three rules of thumb for choosing surge protection Familiarize yourself with types, or categories, of SPDs. Assess the risk of lightning strikes and discharge capacities. Use the right devices to protect the surge protection itself.

Can you have too many joules?

You can have all the Joules in the world, but if your clamping voltage is too high, you could still get surge damage. Clamping voltage refers to the amount of voltage that will cause your surge protection to kick in. Lower clamping voltage = better surge protection.

How many joules does a person need per day?

If the average human consumes 1500 calories each day, that translates to 6.27 × 106 joules per day. Relatively speaking, this is about the amount of energy required to run a car for 15 minutes.

What is a good voltage protection rating?

Look for a joule rating above 600. Response time measures how quickly the surge protector reacts to a surge, measured in nanoseconds. The faster the response time, the better the protection. One nanosecond or less is ideal.

What is the 30 second rule for lightning?

When You See Lightning, Count The Time Until You Hear Thunder. If That Is 30 Seconds Or Less, The Thunderstorm Is Close Enough To Be Dangerous – Seek Shelter (if you can't see the lightning, just hearing the thunder is a good back-up rule). Wait 30 Minutes Or More After The Lightning Flash Before Leaving Shelter.

What is the highest joule surge protector?

The best surge protector or best power strip in our opinion is the APC Performance SurgeArrest 12, model P12U2. The unit offers 4,320 joules of protection, along with 12 electrical plugs and two USB ports.

How many joules do I need for an AC surge protector?

Generally speaking, surge suppressors of 1,000 to 2,000 joules are acceptable for smaller electronic devices such as smartphones and tablets. For computer systems and other larger equipment — or if you simply want the best protection possible — look for something rated above 2,000 joules.

What is the best energy efficiency on a TV?

Modern LCD and LED TVs are considerably more efficient, with LED TVs being most efficient. 94% of Energy Star certified TVs are LED TVs. 89% of these are direct-lit LED TVs, while 11% are edge-lit. TV wattage varies considerably with screen size and resolution.

Do modern TVs need surge protectors?

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. A power spike or power surge can shorten the life of these devices or even wipe out all of your data.
