The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.

4/0 (4 ought) in copper will handle 250 amps. The voltage drop at 175 ft. is about 2.14 volts which should be okay.
Power = (current) x (voltage)2,000 = 8 VV = 2,000/8 = 250 volts if the power factor is ' 1 ' and everything is operating as marked
250 kVA generators come in different voltage settings and this information is needed before a wire size can be given
There are two distinct questions here. To determine the wire size to carry 15000 volts the circuits load amperage must be stated. The wire size for a 550 amp service is, an 800 MCM copper conductor with an insulation factor of 90 degrees C. This conductor is rated at 555 amps. Parallel 250 MCM will give you a total capacity of 580 amps. A triple run of 2/0 will give you a total capacity of 585 amps.
Yes, you could, but why would you? Maintenance or fault testing on a cable rated at 600 volts involves applying the rated voltage (600 volts) and measuring the leakage current. Doing this test at 250 volts doesn't really test the cable. High potential (hipot) testing involves the application of even higher voltages for test purposes.
10 amps 250 volts or 16 amps 250 volts.
A 220 volt line may put out 250 volts because this specification features voltage that varies between 220 and 250 volts. In other countries, the electricity varies in voltage between 110-120 volts.
and breakers that can only hold up to 250 volts
How do you adjust an F-250 shifter cable? 2000 model
12V.
Almost every home in north America will have a 240 volt supply (250 volts is the same).
150-250 volts
Yes, that is safe.
12 Volts.
NO
The battery is 12 volts but the alternator generates about 13-14v to charge the battery.
