This split bus panel has two lower sections each fed by a 60 amp breaker in the upper section.
The current through the stab will split at the attachment to the buss, coming in from the main, some crossing to the new branches, and some going onto the buss. This will likely result in less heating than all the main current passing through the buss connection, which is likely a higher resistance than the stab crossing from left to right.
