Hire a licensed Electrician to look things over.
Assuming 208V and a safe 1,500w per miner * 14 = 21kW = 101A total so *should be good. Since there is something major screwy there...
This is NOT something for DIY or 3rd-party remote guessing!
yeah you are 3 phase so loads must be balanced
1+2
1+3
2+3
are the combos of the three phases
so the most load any can do is 66.6 x .8 = 53.28 amps
so
1+2 < 53 amps
1+3 < 53 amps
2+3 < 53 amps
but also balanced
so if the gear is 102 amps what is all your other shit say 30 amps
that is 132 amps of your 160 amp 80% derate
you are going to need some one with meters to see what each leg is doing
and to see if you are close to balanced.
can't fix via the forum
