Conductor ampacity adjusted for pickup

[mbrooke]

Does relay pickup or fuse TCC require consideration in conductor sizing? My fear arises from the potential of having a fault above the feeder STE (Short Term Emergency) rating, but below the 200-250% pickup.

Are you asking if the OCP TCC needs to be inside of the conductor damage curve?

If so - yes
Although occasionally on will see the damage curve creep inside on the TCC for a short piece
