Electrical supply for seti farms

A very good article at overclockers.com regarding power draw and household circuit wiring. I found the discussion in the folding section of the forum but it is worth repeating here:

New circuit breaker and wiring is very inexpensive. Restoring a house following a fire due to overloaded circuits is much more expensive.

I have run my new 20 amp circuit for the farm. Have you?

Good thing is that here in Croatia we have 220Volt 50Hz lines. So I have 3 phases with each having an 16Amp breaker on it.
So I can plug up to 3520Watts on each phase without worry of overloading.

Similar thing here in England with 220volt 50hz all my rigs are on a seperate line to every thing else with a 32amp breaker. But an interesting read thanks eaglescouter.

Total capacity 7040 watts. 80% capacity 5632 watts

I did something like that a couple years ago myself. I ran a 3 wire split phase circuit that has 2-20 amp breakers, 1 for each leg of it to the computer room. So I ended up adding 40 more amperes of capacity to the computer room, which ends up being 32 amperes of total usable current (80% rule). And I actually measured my current draw after installing the extra circuits and including the air conditioning power draw for the computer room, my farm pulls around 38 amps total (on 4 different circuits, the 2 new additions and the original 2 circuits).

Hmm.. 230V here in NZ. my pc is on a 20A breaker, so thats 230*20=4600W? I was never really good at the physicsy kinda things ;D. Its still very tempting to get 1150*4W UV cathodes and put them on a dedicated 20A breaker haha.

Thanks for the link.. that picture of the house really made me think about what can happen =\

Here in Denmark I have 220V also. My curcuit runs of 13Amp breakers - which would be....220*13= 2860Watt?

My house has 4 breaker to cower entire house..(with dryer and other "heavy" on a seperate 25Amp breaker)

here in switzerland, its 220v, and i think its 10a per breaker. And I think thats sharing the same circuit as my sisters room. luckily, only have the one rig (2, if you count my sisters) and mine probably only draws ~375w (hers is a stock emachines, celeron, probably 200w max).

Good point, eaglescouter!

I hadn't really stopped to think of the power draw in this room, which also includes a home entertainment center. I do have two UPSs running the computers and another one on the stereo rack but that won't stop a circuit over-load in the house.

Let's see, 530W for the computers (3x s939 rigs) according to the APC monitoring programs, which doesn't include my 20" CRT so figure 600W total (5+ amps), old 2100+ rig & LCD monitor (1 amp?), overhead lights & fan (~3 amps), stereo rack & 54" projection screen (don't wanna' know!), not to mention the garage door opener, plus a few other small misc things. Thank goodness I had the foresight to run a new circuit for the booster A/C unit I installed a couple of years ago. Even at that I may need another circuit for the entertainment center. Good call - I'm glad you got me thinking about this ...!
