Setup Questions - Whatsminer M32 54TH

cooler minds prevailed. Waiting on a NEMA L6-20P to C19 cable to be delivered. I need to swap out the outlet from a NEMA 6-30. Does it also need to be a NEMA L6-30 or would a NEMA L6-20 suffice? Does the power cable need to be L6-30 as opposed to L6-20 (the one I ordered)?

In North America, 'Neutral' and 'hot' usually are not relevant terms when it comes 208 and higher. There is no neutral connection supplying power, just two hots, L1 & L2 which goes to which pin does not matter (just keep ground as ground!).

In Europe and other countries where the wall plug voltage is 220V yes one pin is neutral and the other pin is hot same as NA does 120v (1 neut, 1 hot) but again, the equipment does not care about the connections.

re the outlet, to keep things easy, go with whatever the male end of the cord is. If it's 6-20P then the outlet would be 6-20R. If the cord is locking (L) then match the outlet to be the same. To keep things fully to-code also change the circuit breaker feeding the outlet to be 20A but frankly I would not worry about it.

thank you.

The male end of the cord is L6-20P which means it should go with L6-30R?

The breaker is a double pole, each with 20A

The male end of the cord is L6-20P which means it should go with L6-30R?

No! It needs to be L6-20R to match the male end of the cord. The 30R is a larger diameter connector meant to mate with 30P.

The breaker is perfect.

Edit - my bad - I see I said 30 in the above post - fixed that....

gothca thanks thats why I double checked!

Received delivery of my Avalonminer 1166 Pro today. I was expecting a new unit but it came pretty dirty so I feel pretty confident it was used. The exhaust fan plugs seem to move in and out a bit but I am not sure if that will make a difference. I have not yet run the machine, the power cable arrives tomorrow.

Is it pretty common for "new" machines to come in this condition? Maybe this is Canaan specific?

[NotFuzzyWarm]

No it is NOT common nor a Canaan thing. Was it sold as new and who was the distributor? It should have been pristine. The fan axial motion is common and can be caused by the type of bearing used. Canaan does final burn-in tests on all their miners but those only run for at most 1-day -- certainly not long enough to make them dirty.

Grant you the A11 is not their current generation and AFAIK has been out of production for a while. It may have been in storage or on a shelf for several months - IN the box - but it should be clean.
