What would be a typical joules rating for a surge suppressor designed for home use?

Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors.
A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.

Why are surge protectors rated in joules?
Joules is a unit of energy. The rating says how much energy they can absorb in a surge without being damaged. If damaged by a surge you better just throw it out.
Can you use a 6 volt charger for a psp?
You should only use a charger that has the same voltage and current rating as the psp was designed for.
What is the difference in 130v and 120 volt light bulb?
Not a lot. The rating is to denote the voltage the bulb is designed for. The higher rating just says it will handle voltage that high so you have a bit more flexibility if your voltage fluctuates.
Can all circuit breakers interrupt large fault currents?
All Circuit Breakers have a current rating and a FAULT current rating. The current rating refers to the current at which the circuit breaker is designed to 'break' the circuit and this is generally shown in Amperes (A). FAULT current rating is generally alot higher rating and is therefor shown in kilo Amperes (kA). This kA rating refers to the amount of current which a circuit breaker is designed to handle under fault conditions and can still maintain operation and 'break' contact. Most household circuit breakers are around 7.5 kA, so any fault over 7,500 Amperes could potentially damage the circuit breaker contacts to the point which it can not open the circuit. Larger fault ratings are found in larger applications such as MCC's on plants, minesites or power stations.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The unit watt is defined as energy per unit time. Thus a 100W light bulb consumes 100J of energy each second. Joules are a unit of energy. Watts are a unit of power.
What is the typical rating of a hot wire relay contacts?

What is a typical rating of a hot wire relays contact?
The typical rating of a hot wire relay contacts is 35 amp
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
Is power rating measured in watts?
yes also knows as joules per second
How many joules per coulomb are given to charges that flow in a 120 volt circuit?
No way of telling. to get amps you have to have a current flow, which you get when you connect a consumer to an outlet. Then the consumer will pull amps according to its wattage rating (Watts / Volts = amps) - assuming it's all hooked to a fuse with enough rating.
Why are surge protectors rated in joules?
Joules is a unit of energy. The rating says how much energy they can absorb in a surge without being damaged. If damaged by a surge you better just throw it out.
What is minimum recommended surge protection for an iMac?
First of all look for a surge protector with a UL (Underwriters Laboratory) rating. If it does not have one you can rest assured is junk. But just because it has one does not mean is an excellent surge protector. Be sure that the product is listed as a transient voltage surge suppressor. Get a surge protector with a minimum of 1200 joules. Normally the more money you spend the better protection you get but, that is not necessarily always the case.
How many traits do a typical behaviorally anchored rating scale measure?
eight traits
What is the power rating of lights?
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
What are the objectives of credit rating?
A credit rating is designed to show an potential lender whether a customer is a good risk. This helps lenders know who is credit worthy by the number associated with their rating.
Nisha's vacuum cleaner has a power rating of 200 watts. If the vacuum cleaner does 360000 joules of work. How long did Nisha spend vacuuming?
Time= 1800
What are electric fence joules?
A Joules is an internationally recognized unit of electrical energy. Manufacturers of Electric Fence Energizers (AKA Controllers, Chargers) like JVA, Pakton and Gallagher, rate their product in Joules. The higher the figure the more powerful the shock the unit can deliver. Unfortunately the industry does not use a uniform means of rating energizers, which leads to some confusion.
