For protectors adjacent to appliances, a shunt type connects energy to other wires. A series type blocks by filtering and absorbing energy. These protectors are rated by the amount of energy it can absorb - joules. A ballpark measure of its life expectancy.
Those protectors are completely different from another type that must be located elsewhere. These other protectors perform differently and protect from other types of surges that more often do damage. These are often rated in terms of current - amps. A ballpark measure of its life expectancy.

What is a surge suppressor varistor?
A varistor is an electronic component used for surge suppression. It is also known as a voltage dependent resistor, but it acts more like two zener diodes reversed and placed in parallel. The majority of surge suppression devices use these. However, they don't work all that well for lightning strikes.
What device should be used to protect a system from over voltage and power spikes caused by dramatic fluctuations in electrical power levels?
The device that you are looking for is called a surge suppressor. It is a small device that can be mounted in one of the knock out holes in the distribution panel. They are a four wire device. It should be connected across a common tie double pole breaker. The two black leads from the suppressor connect to each of the terminals of the two pole breaker. The third white lead connects to the neutral bar of the distribution panel. The forth green wire connects to the ground buss, (not to be confused with the neutral bus). With the breaker turned on it continuously monitors the voltage of the distribution panel and automatically sends power spikes to ground.
What unit or measurement is used to describe the amount of work a surge suppressor can do before it stops protecting the circuit?
Depends 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.
What is a surge suppressor is designed to do?
When the power applied to a surge suppressor goes above the rated amount, a certain amount of that power diverted down a ground wire and dissipated. Surge suppressors wear out and should be replaced every two years. Answer: Any suppressor that degrades or 'wears out' in two or ten years is grossly undersized, is ineffective protection, and may even create a fire. Suppressors must be properly sized to not fail. For AC mains, a suppressor must connect short to earth (be adjacent) to what actually absorbs energy). Suppressors that make an effective (short) connection to earth are also rated at least 50,000 amps. To not fail even on direct lightning strikes. An effective suppressor connects transients (even tens of thousands of amps) to what harmlessly absorbs that energy: earth ground. A completely different suppressor adjacent to an appliance must somehow block or absorb that energy. These hundreds joule devices require frequent replacement when absorbing destructive surges that exceed tens of thousands of joules. Suppressors that need frequent replacement are undersized and are typically too far (many tens of feet) from earth. Completely different devices, called suppressors, last for decades and are located adjacent to earthing electrodes.
The two types of cell cycle genes if mutated cause cancer cells to divide uncontrollably are called tumor suppressor genes and?
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
What are two types of genes that when disrupted can cause cancer?
The two genes considered responsible for the cause of cancer are the oncogene and the tumor suppressor gene.
Why cancer is caused by multifactorial traits?
because it have two clases of genes involved: oncogenes and tumor suppressor genes
How do you build a suppressor?
Many books have been written on the subject. Your local library or gun shop should have one or two.
How can I protect my devices from power surges using only one outlet with two surge protectors?
Using two surge protectors in one outlet is not recommended as it can overload the circuit and increase the risk of a power surge. To protect your devices from power surges, it is best to use a single surge protector with a high joule rating and plug your devices into that. Additionally, consider using a power strip with surge protection for multiple devices.
Can you use two single phase surge protectors instead of one three phase surge protector?
No, using two single phase surge protectors in place of one three phase surge protector is not recommended. A three phase surge protector is specifically designed to protect all three phases of a power system simultaneously and provide comprehensive protection. Using individual single phase surge protectors may leave some phases vulnerable to surges and compromise overall protection.
What does two fuses in series do?
Two fuses in series could be used as a tap point to pull current to another circuit between the fuses, some times there is a surge fuse designed to blow in the event of an outside voltage surge or a sudden appliance surge due to internal failure.
What is the difference in two surge protectors in series vs two in parallel?
Surge protectors in series will limit based on twice the voltage of one surge protector because, implied by Kirchoff's Voltage Law, voltage drop across components in series is additive.Surge protectors in parallel will protect based on twice the current of one surge protector because, implied by Kirchoff's Current Law, current through parallel components is additive. (Yes, I said "protect" instead of "limit" deliberately because this is a different situation.)However, the parallel configuration is problematic because it depends on the turn-on curve of the surge protector. If one turns on first, and limits the voltage to a specific value, the other surge protector might not turn on at all. In the general case, this will not be a problem, because the turn-on curve does not have a vertical slope, but it would be advisable to consult the device specifications before contemplating this configuration.
