Now we need to add the power conductors for the supply line and all the loads to the list.
Consider an average conductor length of 1.5 m (just the length internal to the panel is to be
considered) and select the wire sizes according to the required standard.
Th e size of the supply line is 350 MCM (this information is provided from MCS Star as well).
Select the [ Busbars/Conductors ] button and select “Add new dataset”.
Select the “Conductor” option under “North America”. Select 350 MCM and a length of
1.5 m. Th
en select the [ OK ] button.
Add all the other power conductors according to the picture below as you did the supply
conductors above. Enter quantities, operating currents and the standard reduction factor of 80%.
It is recommended to consolidate the conductors for identical loads, as shown in the picture.
