I thought across the line starters had 2 MCs just for this very reason? If they won't go to a soft start, at least get the second coil in there. Chances of both welding shut are the other side of remote.

Chances are with proper ventilation if there is no fire, nothing will go off for fire or shunt trip. Remember our ambient temp for oil is around 100 degrees, I think TKE usually has their viscosity shut off at around 150. Wonder what the boiling point was?
