Supply questions from novice

[Lex Cramer]

Hello,
i've done a bit of research but dont know what im talking about and have a few questions before i garble down the phone at an electrician if anyone can help..

I want to run computer servers/processors in my home and put them all in the spare room so i can control the environment, if i can do what i want to, peak power draw could be 12kw, so as i understand it to run safely with 20% headroom i'd need 2 60 amp circuits? 120*120=14400watts?

My fuse box has a main circuit breaker rated at 100amps, but the ratings of all the fuses in the box add up to 202amps. so shouldn't the main breaker be rated to 200amps?
if i have a 200amp supply to the house is that the maximum the mains supply cable from outside can provide or could i can have a 2nd 120 or 200amp fuse box installed and run the circuits off that?

thanks

this needs thinking out properly. 12kW is a lot. will all the equipment be drawing power at the same time?
your 100A supply is 23kW, so should handle the extra load when you consider diversity. that's the reason your fuses add upto twice the main fuse rating.not all appliances are in use simultaneously.
you need an electrician to calculate the loading and capacity of the installation before progressing any further.

op, how big the server, drawing 12kw?

The ratings of the OCPDs are what they are rated at, not what total current will be, for example a 32 A OCPD for a ring circuit (sockets) may only be taking 10 Amps or so it's what you plug in that draws the current.

the op must have severs like google.

12kW ain't servers, buzz. it's Mission Control.

 

[buzzlightyear]

he must be work for space x then.

I work in telecoms dealing with customers such as BT, Virgin, Telefonica, Google, BetFred and all the big names and we don't have servers drawing that amount of power.

How have you worked out your power requirement?

Just because the main fuse holder says it's 100 amps, doesn't mean to say it's 100 amps.

It could be 60 amps

is that a big hole for his servers when the floor claps in!

There are other subtle issues that might kill you, such as high earth leakage currents. Get a proper electrican in.

Sounds like it
Might be cheaper to rent an industrial unit with the proper setup.
By the time you've altered you're domestic setup the bottom may have fallen out of the market!
Or getting in on one of the "lease" schemes.

Not saying that you actually need 12kW, but if you did, then you need to get rid of 12kW of heat out of that room too. Air handling plant required
