Sounds like poor design that the copper would bust before the overlaod/pressure switch kicked the compressor off. Copper typically requires a LOT of pressure to bust, normally the compressor would trip on overload or throw a breaker first. Have you monitored the pressures when the unit is drawing excessive power? Have you considered replacing the pressure switch with somehting that has a lower pressure cutoff?
