If This Is For Say A House Or A Distrubition Center, I Would Use 000 Which Will Handle Around 240 Amps With No Problem. I`m Sure This Will Handle It. At Anyone Time You Would Or Should Never Have The Loadcenter Maxed Out ( If This Is For A Home ) And If You Fill You Might Or Are Only Running One Item On This Wiring At 250Amp, You Will Have To Install 0000 Cable. Hope This Helps

To carry 250 amps safely, a wire with a minimum gauge of 1/0 (pronounced "one-ought") or larger is typically recommended. It's important to consult local electrical codes and standards to ensure compliance and safety. Additionally, factors such as distance, insulation type, and ambient temperature should also be considered when sizing the wire.
