| Spear, Dave. Electronic Mail. | “We dose current to the chest in units called joules (watts/sec) and use 200 to 360 joules per shock.” | 200–360 J |
How many joules is enough to kill you?
80 Joules
How many joules of electricity can kill you?
Henderson states, according to long established principles, an object which impacts a human is considered 20% chance of being lethal, with a head strike, if its kinetic energy is greater than 80 Joules. 90% chance of being lethal, with a head strike, it its kinetic energy is 150 Joules.
How many joules is a lightning strike?
one billion
Is higher joules better?
All about the 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.
Is 300 joules enough for a surge protector?
Anything 300 and under, clamp voltage is good. You would need to add up the wattage used by each item then usually double it to be safe. It depends on how sensitive each of those components are to surges. A surge protector rated for 1,000 joules will protect your devices from surges of 1,000 joules or less.
Is 450 joules enough for a surge protector?
Valuable Equipment Needs a Higher Joule Rating Obviously, the higher the value of your equipment, the higher the surge protector joule rating required. A surge protector with 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers.
What is the best brand of surge protector?

What can you not put in a surge protector?
Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords. These appliances have higher power capacity and need to be plugged into a wall outlet directly. Rule number three: always plug power strips directly into the wall.
How many joules do I need to protect my 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 do I choose a surge protector?
You’ll want something at least 6-700 joules or higher. (Higher is better here.) The clamping voltage is the voltage that will trigger the surge protector—or essentially when the surge protector wakes up and starts absorbing energy. Look for something around 400 V or less.
Does a TV need a surge protector?
You don’t need a surge protector for your desk lamp or your standing fan, but you do want a surge protector for expensive devices that have intricate microprocessors, like computers, televisions, stereo systems, and media centers. In short, anything electronic and expensive benefits from a surge protector.
How many joules do I need for a refrigerator surge protector?
2000 joules
