So far, the rental places i found all have something like 40 amp maximum load in the room. With 40 amp at 230volts, that means around 9200 watts only, about 6-7 antminer S9s can be used. Not very attractive considering the rental amount.
U guys ask the landlord permission to modify it somehow?

can still be worth it, what is the rental amount? consider that 7 of those thing can do 2.2k+ a month depend on btc value
even if you pay 500 for the rental you should come up with 1700 net or minus consumption
still only month to roi, I would try to gamble with this, seeing how the investment isn't too big

I am pretty sure the return isnt that high for mining BTC. It will take months to recover. Hmmm Is there a trick to get the electrician to wire the area with more electricity? Does it cost more?

I would not put more than 5 Antminer S9s into a 40 amp 230 v circuit. Don't forget to derate 80% if you are following NEC; you don't want to trip the breakers, or worse cause an electrical fire if the breakers aren't sized properly. Hire an electrician to determine if there is more available power, get permits from the city, and also keep in mind the ventilation requirements to keep the equipment from overheating.

Too new for answering this question. I'm actually needing answer to these questions as I might get into mining if I start understanding it.

I haven't knew there is an amp limit. What the difference in having a building with thousands of PC's with way more amps? Probably the noise would be to loud anyway?

Does somehow pulling the electricity out from nearby cost alot. Any rough guidelines? Is there any rental location in a city where there tends to be more availability of AMP for more use? :s11: Or some kind of service that caters to these type of electrical needs? Juz look for industrial areas? Too new for answering this question. I'm actually needing answer to these questions as I might get into mining if I start understanding it.
Hang around here then buddy. I haven't knew there is this amp limit. What is different from having a building with thousands of pc with many more amps? Probably the noise would be to Lound anyway?
There is only so much a socket can handle. The problem is u can have even 5-6 sockets in a room and it could be such that all 5-6 can only handle up to 40ampere max....

The amp limit was simply referencing the available power specific to the OP. The closer you get to the breaker limit the greater the chance or breaking the circuit or if not properly protected, starting a fire. Also, you have to make sure the wires are sized properly for the current flowing through the circuit. An S9 pulls nearly 1500 watts, a general use computer pulls an average of 500-750 watts depending on the setup. You can have a building with thousands of computers or thousands of S9s as long as you have enough power and ventilation for your setup. On a 40 amp 230 v circuit you can only have 5 S9s or 10-15 computers, assuming they are running 24 hours a day. I'm not talking about mining rigs, I've haven't built one yet, just talking about general computers.

Yup, be very careful about loading a single circuit with too many rigs, the biggest worry is starting a fire. Most circuits are setup to match the type of wire in the wall so that they will trip before too much current is passing through the wire to heat it up and cause a fire. Just make sure that not only the circuit on the breaker, but the wiring in the wall was setup to code and the landlord didn't just swap out the breaker for a bigger one without putting new wiring to handle the additional current.

It practically never makes sense to rent an apartment, even one with electricity included, solely for the purpose of hosting a few miners. If the primary purpose is to have a place to live and hosting the mining operation is secondary, then it makes sense.

Does it cost more? well just go over the calculator, it's actually that high now a bit less because there was a recent dump but an antminer is doing $350+ per month, you do then an easy math and see that it's true, roi isn't that long, but the diff won't sit there well for wiring the area for sure it cost you something, but this must be asked to your local electrician

Where are you? That must be some other country because there is no place here that can control the amps going into your unit and room or whatever. The worst that I have seen here is a sublet situation where they might kick you out or raise your rent if the end of the month showed a high electric bill, but that is it.

Most of the time you either go big with a larger location that was built to have a lot of electricity or you find ways around it, like asking the landlord to permit having a larger power supply installed, which, when I was going through and trying to get involved in the mining game, was something most landlords were willing to accommodate provided the area was already industrially developed, meaning a warehouse or some similar form of storage location. If ti was a domestic or commercial location then there was zero chance from any of the landlords I asked. Most places that offer larger supplies are industrial areas, in my area at least, anyways.
