The surge arrestor is clipped onto the rail in the DB next to the existing breakers, the live (red) wire is looped from the existing live loops above the other circuit breakers onto the top of the surge arrestor. The bottom of the arrestor is connected to the earth bar. It would be better to install a seperate earth spike and connect the botom of the arrestor to that to make sure that you have a good earth but it is sometimes not possible if the DB enclosure is indoors.

Where be the surge arrester be placed?
Before the object on the positive and after on negetive
How the voltage arrester works?
The voltage arrester works by conducting when there is enough voltage to turn it on. Often, an arrester on a primary distribution circuit has a spark gap to ground, so that lightning strikes are limited in voltage, protecting the circuit. Other types of arresters, such as MOV's, can be used in surge protectors.
What if surge protector had high resistance?
If a surge protector had a very high resistance at all voltages, the wires in the surge protector would short out. It would kick off the protector and make it useless. A new surge protector would need to be purchased.
What is a surge in voltage or current in an electrical circuit called?
A transient, surge, spike, etc.
Does every surge strip have a built-in motherboard?
Yes, most of the surge strips have an in-built motherboard.
What are five types of surge arrester?
There five types of surge arrester: 1. Rod gap arrester 2. Horn gap arrester 3. Protector tube or expulsion type 4. Thyrite lighting arrester 5. Gapless arrester or metal oxide arrester
What will you do if the surge arrester is damaged?
Replace it.
What is MCOV rating for lightning arrester?
It is Maximum Continuously Operated Voltage to select the rating of Surge arrester or lightning arrester.
How can you rate surge arrester?
check NEC
Where be the surge arrester be placed?

How do you know if you need a surge arrester?
1. If there is fluctuation in electricity and you are using manual stabilizer. 2. If there is improper earthing or earth leakage. 3. If you are using d,ble earthing.
What is difference between surge absorber and surge suppressor?
There is likely no difference. Neither is accepted terminology for a surge suppressive device (SPD). If these products have been tested by safety organizations such as CSA (Canada) or UL (US) or tested to international surge standards (IEEE, IEC), then they should bare the correct terminology, otherwise, they are not tested to provide protection to equipment during a surge. Surge Absorber acts as a load that utilizes the high current until it exhausts. but the surge suppressor diverts the high current into ground without reaching the sensitive parts of the circuit. Surge absorber degrades faster than a surge suppressor.
What happen when you use 6.6kV instead of 11kV surge arrester?
The 6.6KV device will conduct before the 11KV device, quite possibly even in normal operation. Don't use it this way!
