ip is calculated using method C
Ib does not include decay of non-terminal faulted indunction motors
Ik is the maximum steady state fault current
Idc is based on X/R from Method C and Ib as specified above
LV CB duty determined based on service rating.
Total through current is used for device duty.
* Indicates a device with calculated duty exceeding the device capability.
# Indicates a device with calculated duty exceeding the device marginal limit . ( 95 % times device capability)
