I'm just about to set up my first mining rig and would like to run my plan by other sets of eyes in case I'm missing something. I have an outbuilding with 200 amps of power available on its own meter, and pay .09 cents per KwH. I just want to start with one rig, so this is the set up. Please correct any issues you see.

I'll be running Sha-256 to mine BTC with either a 140Th Bitmain SXP19 or a 186Th Micro BT WhatsMiner M60s. They both operate at 240v 3100-3500w so the amperage should be 13-15, which means a 20 amp circuit should be sufficient for one given the 80 percent max safety margin. My plan just to get one up and running is to wire a double pole, 240v, 25 amp circuit with 10g wire and a L630 receptacle and a basic PDU.

The outbuilding doesn't have internet, so I'm planning on setting up Starlink on the unlimited standard date plan and using the Ethernet adaptor and as I add units an ethernet splitter. The plan will then be to join a pool via poolin or something comparable.

This is my first attempt at mining, and I'm just trying to conceptualize a way to work with what I have. All of the higher performance miners seemed to be three phase power, which I lack. I appreciate any input and constructive criticism.
