I appreciate that. I am indeed very new. I think that I have identified that the breaker is 100A for where it is located. I would find it helpful to learn how much load each outlet could take and I shall seek an electrician to identify the answer. Could you tell me what type of power cable to use and with what fuse should be in it? I've read that a PDU could be used, but I don't know of how many Amps that should be or how many S9's could run off of it, if it were say 30A. Could you enlighten me on the power cable and PDU side of things please?
As mentioned that 100A breaker is most likely a sub-panel or possibly the main breaker for your panel. Maybe you are in a very small house or apartment? Anyway, there should be other breakers, these are the smaller ones running to your outlets and appliances. So you need to know *exactly* what the outlet is rated at that you will plug the miner in to, you do that by finding the breaker for that outlet.
There's no fuses to worry about, you need to just use the correct gauge (size) wire and ends that match the wall plug and power supply. I would use a power cord that physically plugs in to your outlet, once you find that outlet's amperage. Luckily they are very common, just make sure the cord is rated for 10A or so.
As far as how many to run off certain size circuits, I think you should consult your electrician on how, exactly the best way to wire up your environment.You can tell him the miner uses roughly 7 amps. But this isn't something you can string off of a bunch of extension cords. So depending on how many circuits you have available, you can plan with your electrician the best way to wire. Let's say you only have one 30A circuit, then your best bet would be a PDU (power distribution unit) and you can safely run about 3 S9s off that on a 30A circuit.
Search around on this forum, pretty much everything you need has been posted, and recently too as there's a TON of new folks buying miners and asking questions.
