Best way to provide individual surge protection for 8 computers on 120V/20A circuit?

Apologies in advance if my terminology or questions are lacking the appropriate knowledge.

I have a client that wants me to make them a riser for their electrical outlets that they have going down a row of 8 desks. They are currently plugged into to a 120v/20amp outlet. Please see the attached image.

Questions


They mentioned having each receptacle protect against surge. The riser is essentially just a fancy extension chord. Will something like this work http://amzn.to/2qCRIPY or is it complete overkill?
Am I going to have problems with overloading the amount of power that circuit can handle? I was told a conservative estimate is 300 watts per computer, which 300x8 = 2400w, which is the exact amount of power that is available. This is how it is currently set up and there are no issues, but is there potential that I may have problems?


Thanks!

First, to protect the receptacle you would need a surge protector. In my opinion it will be overkill if you'd use one for each. But you never can say when it comes to safety and the additional cost may save more than a damaged unit.

Second, "electrical wiring("")":http://www.ccautosoft.com/2011/04/setting-up-an-internet-cafe-part-3-electrical-wiring/ I would suggest using high quality wires for this.

Hi Summerville & Duke,

Most of the disturbances entire the circuit through the ground if the ground circuit is
not properly grounded pl see my attached file for further reference and review my
score.

These are good stuff here. Very nice write up.
