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

ProfessorTo 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.

A 250 MCM copper wire is with an insulation factor of 75 and 90 degrees C is rated at 255 and 265 amps respectively.
A 350 MCM aluminum wire is with an insulation factor of 75 and 90 degrees C is rated at 250 and 260 amps respectively.
4/0 copper or 300 Aluminum unless you run into voltage drop

250 MCM copper is good for 300 amps
350 MCM AL is good for 300 amps

What wire size in a 20 amp 250 volt circuit?
For a 20 amp 250 volt circuit, you would typically use a 12-gauge wire. This wire size is rated to safely handle the current and voltage requirements of the circuit without overheating. It is important to always refer to local electrical codes and regulations to ensure compliance.
What wire size is required for 312 amps?
A wire size of at least 250 MCM (thousands of circular mils) is typically recommended for a current of 312 amps. Using wire size calculators or consulting with an electrician is advisable for specific installations to ensure the correct wire gauge is used for safety and efficiency.
What is the ampere rating of 250 mcm inverter duty wire?
A 250 MCM copper conductor with an insulation factor of 75 or 90 degrees C is rated at 255 and 290 amps respectively
What is the amperage of a standard power outlet in China?
10 amps 250 volts or 16 amps 250 volts.
How big a wire do you need for 6 amps?
The wire can be as big as you want to carry 6 amps. As a comparison, the smallest home wiring power circuit uses a #14 size wire and it is rated for 15 amps. In the UK a wire of 0.75 sq. mm is rated at 6 amps for portable appliances with occasional use. For a permanent installation a cable of 1 sq. mm. or more should be used. House wiring uses 2.5 sq. mm cable in a ring circuit to supply power sockets.
