Edit not sure how to send or show a photo of my set up but I essentially made my own PDU and protected it with the watch dog. So I ran a 60 amp circuit with #6 wire to the watchdog then I ran #6wire from watchdog to a small 8 space panel that I have 4 20amp 240volt breakers installed in that feed my asic miner rigs. This protects my rigs and let’s me see my electrical consumption thru Bluetooth app.
