Hi there guys I just converted my farm to 240. I was wondering what the amp draw of 1 Antminer s7 is on 240 volts!!

It is a 50 amp circuit. The breaker keeps flipping with 1 antminer s7 and 7 antminer s5 with the power factor a 1. The amperage for an antminer s5 is 3 amps and antminer s7 is 7 amps. So 28 amps on a 50 am circuit no problem but it does not work. It will run for 1 hour and then trip. Any help is appreciated. Thanks

AntMiner S5: 590 watts

AntMiner S7: 1,422 watts

Assuming a power supply efficiency of 80%, the S5 would consume 708 watts from the wall, the S7 would consume 1,707 watts.

The total for 7 S5 units and 1 S7 unit would be 6,663 watts. On a 240 volt circuit, this would be 28 amps of current.

A 50 amp circuit should be sufficient to power this with a wide margin, so I would suggest verifying there aren't any additional loads like a hot water heater, range, or clothes dryer on the same circuit. Also, the minimum wire size should be 6 AWG from that breaker, any smaller could cause issues.

If it is an old circuit breaker, that could be part of the issue as well.

Also, purchasing a clamp ammeter would be an easy way to check at the circuit breaker the current draw. Here's the one I use:
