Hello I am wiring up a 100amp sub panel in my shop the run is about 230 feet so I was advised by the supply house to use 1/0 aluminum, I was told that the breakers at the main panel at the house would not accept the 1/0 aluminum, what would be the proper way to connect the wires I have seen like step down pins that could be used but not 100% sure if they would pass inspection thanks
