Power in China

[sblair]

I'm in the process of specifying decent size server room over in Beijing (130 Servers.)

I know everything over there is 220V single phase.

Main question I have is what is the common ampacity of the circuit breakers over there for convenience outlets? i.e. what is their equivalent of the 20A service we have over here in commercial buildings?

Also, anything else that is useful to know? I'm planning on specifying 5000VA 220V UPS's in all the server racks.

Thanks.
Scott

Installing 130 individual 5kVA Rack-Mounted UPS is a very wasteful, inefficient way to provide power, plus it will be a maintenance nightmare.
Think about a central system.
Individual units waste power and Rack Space. They also tend to run hotter than the 77 degrees F that is recommended for the batteries.
Think about a central system.

make sure that you specify that all materials and equipment are made in the usa.

Looks like they use something very similar to what we have here in NZ!

I'd be surprised if the standard for power distribution in data centres wasn't C17 (CEEFORM) connectors though.

And seconded on hundreds of toy UPSs, a long way from normal practice.
