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

What is the max amp rating for 4-0 Copper Wire?
250 amps maximum.
What wire size in a 20 amp 250 volt circuit?
The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.
400 amp service what size wire?
A 750 MCM wire with an insulation factor of 90 degrees C is rated at 500 amps. De rated to 80% will allow 400 amps on the wire. A 900 MCM wire with an insulation factor of 75 degrees C is rated at 520 amps. A 1500 MCM wire with an insulation factor of 60 degrees C is rated at 520 amps. Parallel 250 MCM will give you the same usage. A 250 MCM wire with an insulation factor of 75 or 90 degrees C are rated at 255 and 265 respectively. 255 x 2 = 510 x 80% = 408 amps. 265 x 2 = 530 x 80% = 424 amps.
How do you calculate a sises of cable used for an appliance?
Wire sizes and ampacity are regulated by code. # 14 wire 15 amps, #12 wire 20 amps, #10 wire 30 amps, #8 wire 40 amps, #6 wire 60 amps. These are the most common, a slight variation in amperage depending on the insulation factor.
