Update:
I have tightened all the bolts in the panel. The bolts holding the breaker to the panel, the cooper wire going into the breaker and the cooper wire going into the outlet. All have been tightened but the problem is still present. Today the outside temps have reached 50f and inside the container its also 50f. Inlet and out let are below 75 for all these miners. But they still stop mining. They are breaking after mining for 20-30 minutes.
