Refer to EV500 Sales Drawing for complete specifications.
1. See EV500 sales drawing for complete specifications, including normal capacitive pre-charge, make plus abnormal make and break ratings. 2. Current Carry: 750 A @ 25oC. Derate 2.5 A/oC to 600A @ 85oC for still air, no heat sink. Reference National Electric Code for specific conductor size recommendation versus current. For >600A carry, call factory and request the "EV500" Current Carry study" for additional data.
