Dear,
I am facing a problem in stormy weather.
Sometimes problems happened and water get to the servers room, where a mass happened.
Let's say I have 10 servers connected on the same electric line.
Does it exist an electric device which can be between the server and the power line, so if 1 server have electric mass, this device will end the electric circuit of this server,and only this server will be crashed instead of all servers connected to same power line?
Thx in advanced.

The device commonly used for that is a Ground Fault Interrupter circuit (GFI). It does precisely what you want (as I know from the outside GFI on my home).

Two potential disadvantages:
1. You need one for each circuit to protect (but they are not expensive).
2. I don't know how you would integrate GFI with a UPS (and this is the bigger issue).

Can you not put things on a platform with 6 inches or so of space and then keep everything on the platform and wiring above to the connection point. That should allow for water.

From where to get them?
and why if they are working with electricity don't work with UPS (Sign Wave)?

Any Home Depot should have them.

About the UPS:  A GFI measures to ground and a UPS outlet is normally isolated from true ground. They have grounded outlets, but you would have to test. Any normal GFI has a test button for that purpose.

You will want a Licensed Electrician to guide you here, install a test and see if it works.

Raised platforms are the normal way to solve this problem. .... Thinkpads_User

Thank you.  I was happy to help and good luck with GFI's.  Do get an electrician.

Yes, that looks good. That is for a "portable" type of circuit. You can also get them as "wired in". But it looks fine. .... Thinkpads_User
