∙ 8y agoDepends on a type of protector. Some protectors work by absorbing energy. These might be rated in joules (pronounced 'jewel'). Are typically hundreds or a few thousand joules.
Another protector for all types of surges works differently. It is measured in amps. For example a typically destructive surge (lightning is one example) might be 20,000 amps. So a 'whole house' protector is minimally 50,000 amps.
Protector must not stop working. If properly sized, it only degrades. Protector that is grossly undersized stops working in a manner that violated the manufacturer's specifications. And that is a potential fire. A typically destructive surge can be hundred of thousands of joules. What does that do to the first type protector that must somehow absorb that energy?
Two type protectors. One rated in joules. The other in amps.

∙ 8y agoThe unit of measurement use to describe the amount of work one type of surge suppressor can do is the Joules. That is a measure of the amount of energy it can absorb.
The unit of measurement for a completely different type of surge suppressor is amps. These are for the many other and destructive type of surges. For example, a direct lightning strike may be 20,000 amps. So a minimal 'whole house' protector is rated at 50,000 amps.
Joules for tiny protectors (to protect from one type of surge) and amps for a robust protector (to protect from all types of surges) ballpark a life expectancy of that protector. And does not define protection.

∙ 11y agoJoules, a measure of electrical energy that is the product of Amperes, Volts, and Seconds. A typical surge might be 1000 volts, 10 amps, lasting 10 milliseconds - this would be 100 Joules. If a surge exceeds the number of Joules that the surge protector is rated for, the device will burn out and protection is lost.

A fuse protects a circuit from short circuiting. Also a breaker is used for this same purpose with the additional advantage of protecting the circuit from overloads also.
identify and describe the three kinds of blood circulation and circuit?
The circuit breaker trips when the circuit it is protecting is overloaded. That happens when the wire is at its limit for carrying current. The solution might be to instal an additional power circuit in the house and to make sure the supply from the street is adequate. In both cases an electrician can advise.
A breaker or fuse in an electric panel is protecting the wire, outlets and switches that are part of the installed circuit. You could plug in an appliance that draws 6 amps and have a 15 A breaker protecting the circuit. The idea for protecting a specific device is to put in a fuse that blows before the current destroys the device. If your 6 Amp device would be destroyed by 6.1 amps then you want a 6 amp fuse. However, fuses aren't that precise so this would be hard to do. A rule of thumb is that the steady state current in a circuit is 80% of the over-current protection. In your case this would be 7.5 amps.
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.

Joule
Joule (pronounced "jewel")
For a circuit breaker to protect anything, it must be wired in series with whatever it is protecting.
"The 15 amp fuse" does not describe the circuit that the fuse is protecting. A fuse is there to protect the wiring in case a device fails. For example, if the fuse is protecting the fuel pump circuit, it's probable that the fuel pump has failed and is drawing too much current. That would be the circumstance with whatever circuit the fuse is protecting; there is either a damaged wire and it is making contact with the frame.
A suppressor is rated in joules, and a suppressor is rated as to the amount of joules it can expend before it no longer can work to protect the circuit from the power surge.I think you can find the answer to this question in Dehn-usa.com's "Lightning Protection Guide" or their "ABC's of Lightning". I put the link under the related links below.
no a watt is a measurement of electricity
Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.
Describe the path electrons take in a simple flahlight circuit.
A suppressor regulates the voltage and makes the power constant in a case of a spike or surge . A protector simply detects the surge and turns the unit off. Suppressor is good for things like computers you don't want to keep turning on and off . Like computers in a dmv or office But terms such as protector, arrestor, suppressor, regulator, limiter, and TVSS describe devices that can perform same or completely different functions. Regulated voltage may mean light bulbs dim or brighten by as much as 50%. Each device can be so different that numbers are required to say what it really does. Even a computer's power supply could be called a suppressor and protector since it does both functions within limits. Most often TVSS, suppressor, arrestor, SPD, limiter, and protector are different words for the same item. Those terms are too subjective to say more without details such as numbers.
