Here’s a Brian picker
Running a LT5 Pro and a S19J Pro 96 on a Tripplite 16amp PDU with a 12GA power lead from PSU to wall and PDU to machines are ran with 12GA power cables too. on a 240/30
Blank minded I realized this is overload on the PSU but so far it’s not over heating at all and everything been running smooth.
Im interested to hear everyone’s thoughts and suggestions cause this just made me laugh and say wtf to myself , is tripplite that good and can handle more than what’s rated? 
How is this possible?
Been running smooth over a month

The PDU is rated 16 Amps but has no built in circuit breaker. It is Agency de-rated to 16A continuous, but has no breaker internally.
The loads split the current between your two miners so their 12 AWG power cables are most likely fine…less than 20 Amps each.
Here’s the question: the pdu ships with an L6/20 plug. That must plug into an L6/20R receptacle. Is the breaker a 20 amp or 30 amp breaker?
The breaker for the wall recept is the only thing preventing an overload …except of course a meltdown of the power cords.
Since you cannot plug an L6/20P into an L6/30R you must have an L6/20R receptacle on the wall. It should use a 20 Amp, not a 30 Amp breaker. Did you change an L6/30R receptacle to an L6/20R receptacle? Is the receptacle wiring 10Gauge? (for 30 Amps) or 12 Gauge (for 20 Amps).
Seems you have a 30 amp breaker (my guess) The PDU is overloaded, but there are no protective devices to stop that (except common sense)

Currently doing a 240/30 amp breaker the plug is a Leviton 2620 30 Amp, 250 Volt, Flush Mounting Locking Receptacle, Industrial Grade, Grounding, V-0-MAX,
Right, so the only thing stopping the PDU from potential failure is the 30 Amp breaker.
Breakers are I^2 t devices so if given enough time it could trip at around 29-30 amps. The time to trip goes down as the current goes up.
That is, if you draw say 40 amps, the circuit will trip immediately.
There is nothing wrong with pulling 27 amps on a 30 amp circuit that is wired with 10 AWG wire.
The PDU with a 12 AWG cord will get hot with a 27 Amp load. Also the PDU couldn’t handle the 20 Amp load it was built for so it was derated on paper to 16 amps. I suspect that the PDU will fail internally eventually with this load. Which is probably why it was derated.
Tripplite makes 30 Amp PDU’s with separate load sections of 8 amps each …which are probably too low for your use. I believe they also have a 30 Amp model with higher output without the additional circuit breakers … but they cost over $100
