    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.
