Hey everyone,
I have an Avalon Miner 1166Pro-78TH, and it keeps tripping the fuses on my PDU (which is C19 to C20). So, I'm considering powering this miner with either 2x C19 plugs or 2x C13 plugs to help distribute the electrical load better on the PDU.
For some odd reason, this miner is drawing anywhere from 15a to 20a at 240v.
Has anyone dealt with this before?
Anyone know if I can power C19 plug with 2x C13 or 2x C19 plugs?

This ^^ is why the general public should not be allowed to tinker with high power devices...
If a device pulls substantially more power than it is supposed to and starts popping breakers/fuses, you find out why and fix the problem. You do NOT try feeding it more power! What, you won't be happy until it fails in some spectacular fashion and starts a fire?
Yeah figure out why is it popping the fuse, for god's sake...
That out of the way, possible causes for popping fuses/breakers:
a. Line voltage is too low, what is your line voltage? Does is vary a lot during the day?
b. What is the rating of the breaker/fuse that trips? The A1166-Pro pulls 3,420w and at 208v line that means it is drawing 16.4A. The PDU circuit must be rated for at least 18A to safely carry that load 24x7.
My guess is that the miner is fine and the OP is simply overloading the PDU circuit.
IF that is the case - lose the PDU and directly wire the miner to a 20A circuit. Without knowing how the PDU circuits are wired it is highly inadvisable to try combining power from 2 outlets to feed the miner and even if one does know how they are wired it is still very bad practice to combine power like that.
Ja Bitmain appears to do that with their miners (2x power inlets) BUT their PSU's are internally using 2x smaller PSU's each rated for 1/2 of the total load and ran in a master/slave parallel mode to form 1 large PSU. They are not directly tying the 2 power inlets together to feed 1 large PSU. With the S17/19's each power inlet feeds just 1 of the (smaller) PSU's which means technically they can be powered by separately protected circuits (but that is still a bad idea).
To the fair, at least the OP asked about the idea before blindly actually trying to do it so kudos to them for that

there are l6-30 to c19 cables. and l6-20 to c 19 cables
you bypass the pdu..
many pdus have only 15 amp sockets they trip at about 14 to 14.5 amps
my hp pdus do that.
they have a main breaker for 24/30 amps
and 4x 15 amp receptacles
they will trip on 3200 watt pieces of gear at times.
i have links for cables
l6-30r to c19

these should be okay if the issue is the pdu socket is 15 amp and tripping at 13 or 14 amps
