Electricity needs for 35 L3+ miners

[TrabajoDeLaNoche]

Hello,

I'm a total newbie in electricity and I have 3 months to set up a warehouse with enough power for 35 L3+ miners.

For the cooling I will be using ducting tubes and air extractors (outflow from the miners and inflow from outside).
For internet I will be using a Lan Switch.

I'm not sure what I need for the electricity exactly.

I'm checking warehouses and they specify this kind of information :

45 amp 3 phase breaker
100 amp 3 phase breaker

How many L3+ can I use with 45 amp 3 phase breaker and with 100 amp 3 phase breaker ?

Also, what does the 3 phase breaker means ? How can I check which plug is on which breaker ?
What is the limit per wall plug ?

Best regards,

Antminer L3+ is 800Watt miner, with 10% variation, some energy is also consumed inside PSU in heating/fans etc so make it 1000W for safe side.
for 35 L3+ you would need 35000W, or 35kW straight for miners,
for cooling equippments, any computer, or other small devices you may add up 2kW,
so it comes up to 37kW, (make it 40kW if you need an air conditioner too.)
now there are two options
1. if you have 220v power line then total current required would be 37000/220=168 Amp, in three phases it would be devided so it becomes 168/3=56 Amp
2. if you have 1100v power line then total current required would be 37000/110=336 Amp, in three phases it would be devided so it becomes 336/3=112 Amp

About phase breakers i can only suggest if you can provide more details, like power line voltage, 45 amp per phase or 45 amp in total (generally they are total ones)

BTW, i am mining with GTX660ti GPU, just to stay in game

Thanks ! I understand now how it works. We will try to find a place with more power in case we want to expand the facility.

Best regards,

you dont need more power in series (i mean to change place)
you can add multiple parallel powers.

it depends on how much power company provide you in one line, you may add lines if required.

I always wanted to have mining farm, How much did you have invested and would be investing in it? and how long you expect to be paid back out of profit?
(just for knowledge)

This is quite funny to be fair. You got money, someone told you that you will make shit loads doing nothing and you bought in without realising that mining is far from doing nothing. I would strongly advise you to spend those 3 month studying about mining, about electricity, data centre cooling, static pressure etc as mining isnt just plug in and leave and watch how money rolles into your bank account and be prepared for massive down times, spending days on trying to figure out what is not working and why and etc ... really ... get yourself informed and educated on technicals or you will burn out your 50k work of investment.

I currently run L3+ units on single phase and 3 phase electricity. I am not going to go into the exact calculations, but will tell you what you need and what to tell the electrician that you need.

You can run 6 L3+ on a 208 to 240 volt single phase on a 30 AMP circuit with a NEMA L6-30R outlet.
You will connect a 30 AMP single phase Power Distribution Strip with a NEMA L6-30P plug to the outlet.
Then when you are running the 6 L3+ you will have a continuous load of approximately 4,800 watts +/-.
This will be the maximum recommended full load on this circuit of 80%.
If you voltage is 230-240 you will be right in specs.
If your voltage is 208 you might be at a load of 83% which is just out of specs but if your electrician says you are OK, then you are good.
You could just run 5 L3+ instead of 6 for a extra measure of caution.

You can run 9 L3+ on a 208 volt 3 Phase on a 30 amp circuit with a NEMA L21-30R outlet.
You will connect a 30 AMP 3 Phase Power Distribution Strip with a NEMA L21-30P Plug to the outlet.
When you are running the 9 L3+ on this circuit you will have a continuous load of approximately 7,200 watts +/- which will be within specs.

So for your current needs to run 35 L3+ you will need:

6 of the above specified 30 amp circuits on 208-240 volt single phase, or

4 of the above specified 30 amp circuits on 208 volt 3 phase.



Do not even think about running the above set up on 110-120 volt.

It is always weird when I see a guy who bough miners first and only after then comes the research for knowledge  
It is a crazy way to go.

I've got almost 3 months to set up everything, should be enough. I got a warehouse with 100amp 3 phase on 220 Volts.
