Use the record drawings to verify the equipment type, system voltage, and equipment short circuit rating. Another option would be to verify existing circuit breaker catalog numbers, voltage ratings, and short circuit ratings Another option is to get the system voltage rating and AIC from the labels on the equipment.

Otherwise, turn to drawings in the Windchill or ODM+ tools to find theequipment details.
