CIRCUIT BREAKER TRIP CONVERSION

Circuit breakers should only trip single-pole or three-pole. The trip conversion logic ensures that the tripping is
either single-pole or three-pole. The trip conversion logic ensures that all conditions that should cause three-pole
tripping do so. Indication of the number of phases that caused tripping is provided.
