WebKnowing required ampacity, determine possible bus bar dimensions from the table. Then check Table 1 to verify that size selected has the necessary ampacity. Example: Assume that required ampacity is 185 amp at 30 °C rise. Table 3 indicates that 1/16 x 1 in. size would probably be adequate. This is confirmed by Table 1 which lists the ampacity ... WebJan 24, 2024 · Also, pinching a copper conductor is rather different from, for example, taking the varying load of a con-rod's big end, but there are some guidelines here. Thanks for the link Chris, one to keep to hand. This is the kind of thing I was looking for and it'd be great to have a similar table for copper / tinned copper / alu / tinned alu etc.
