I'm trying to set up my first ever antminer s9. How can I find out what ampage my sockets supply are? I'm in UK and google says that UK sockets are either 3A or 13A. I don't know how to acquire this information but feel it necessary to learn after reading the following section from the antminer quick install guide.
The antminer s9 total current is 20A, but most home outlet power sockets supply only 10A. For your safety, if operating the antminer s9 at home, power it via two sockets located on separate power rails. If you are unfamiliar with residential electricitiy wiring, Bitmain recommends not using this miner for home mining.
The latter suggestion is quite unsatisfying. Any advice greatly appreciated.
Furthermore, do I need to look out for anything special when buying a power cable or will something standard like this be adequate?
