Considering using 1/0-1/0-1/0 aluminum sheathed wire for connection between 200 amp GE box and 100 amp GE box (100 amp breaker to 100 amp breaker)

A GE # THQL 2 pole 100 Amp CB can handle a maximum of #1/0 wire.

If this is a second panel fed by a Main panel, the feeder must have 4 wires, 2 for hot, 1 for neutral, and 1 for the equipment ground.

Ask for 4 wire aluminum SER cable.

The added panel will need a separate equipment ground bar bolted directly to the panel using machine thread screws. The neutral bar must be insulated, do not install bonding jumper.
