I have a Whatsminer M32-54TH miner arriving soon. I couldn't find a spec sheet on this specific machine but did find a Whatsminer M32-68T spec sheet which was as close as I could find here:
https://whatsminer.com/mall/parts/41.htmlAnyone know where I can find a spec sheet for this specific machine?
Given the spec sheet showing
3312W +/- 10% I calculate a maximum wattage of
3643W.
Given the spec sheet showing P21D
AC200V~277V, and using the 3643W from before, I did
3643W/200V=
18.216ampsMy understanding is that I shouldn't draw more than 80% of the rated amperage on the breaker, so a double pole 30 amp breaker seems necessary.
I need to run about 40 feet (12 meters) of wiring to an outlet that will be installed for the miner. Using an AWG chart I estimate I will need to use an 8 guage wire for this length. Do I need to make any extra considerations given how long this cable is?
As for the power plug for the miner, the spec sheet shows it need a C19 connector. I am unclear what type of plug to use. Here is the NEMA plug chart
https://www.stayonline.com/product-resources/nema-straight-blade-reference-chart.aspDo I need the
NEMA 7-30 to support 277V and 30amps or would the
NEMA 6-20 supporting 250V and 20amps suffice? Does the cable abide by that same 80% rule I referenced earlier, or does that only apply to the breaker? In the case it only applies to the breaker, would I then need the
NEMA 7-20 supporting 277V and 20amps? I'm not opposed to making this cable if I need to (I'd prefer to buy it) but I just am unclear on what I need.
Please let me know if these calculations are reasonable and provide any insight. Thank you.
