I apologize in advanced for my poor technical lingo.
I have a spare house which is strictly using electricity to power some servers. I'm slowly building out a cluster, but before I move it to a warehouse I want to have everything up and running and profitable.
Right now I use about 2 KW, I have them on various circuits through out the house so it doesn't trip the breaker.
I live in the USA, I think I saw 100 Amp, 50 Amp, and 20 Amp breakers, so theoretically I could run at least 12 KW. If I had an electrician modify the circuit breaker so all the servers ran in the garage, which is 20 feet away from the breaker.
I'm looking at cost efficiency, I don't want anything permanent done, no rewiring the house or anything, just a temporary setup while I build up capacity. The wiring could be laid on the floor instead of the walls & attic. All it needs is standard wall outlets to plug in the servers.
I'm concerned about two things, obviously safety, and cost. I kinda want to do it myself, I'm interested in learning/doing these things, and I have a background in Mech and Software engineering. Preferably I'd watch and learn from an electrician, how much would you estimated it cost for it to be done? Anything I should know about my plan?
I live in a very low cost standard of living state so I imagine it won't be too much.
Each server uses about 1200W continuously. They're running as a generic desktop configurations. they're not standard generic servers for a server farm, so they use a standard 120V supply.
I have taken into consideration HVAC, and plan to use a large fan to push the hot air out the garage door, as a temporary setup. So accounting for the 20% max load rule, I figure I can run 8 rigs.
Also, the electric box on the outside of the house said 100 AMP, the circuit breaker doesn't have any labels, it's a 40 year old house. Nothing else will be running, Dryer, AC, Electric Stove, etc. Also wouldn't the 20 AMP breakers in the garage/kitchen run on the 240V circuit? Wouldn't it be costly to convert it to 120V?
Spacing it in my house to run off each circuit probably is the best cost efficient idea, but I'm not too keen on running 8 Ethernet cables throughout the house as a potential hazard, and moving a monitor through the house for any maintenance is a pain.
If an electrician did come out and rework a temporary garage setup so I can run 10 KW from the garage, how much is a rough guesstimate for the cost? I'm trying to factor it into my plan before I make any hard decisions.
Thanks guys, you've been very helpful!
