The current (amp) capability is determined by the wire size in gauge, rather than the voltage rating stamped on the insulation.
The most basic rating is 20 Amps for 12 gauge and 15 Amps for 14 gauge wire; however, it can get more complex than that for long runs of wire or for wires run through conduit with other wires. Hire an electrician if this sounds bewildering.

What is the difference in 30 amp 250 volt and 30 amp 600 volt?
Devices are rated by voltage and amperage. If you have a source rated for 600 volts you can use a 250 volt device, but not vice versa.
Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?
No !
Can you replace a 13 amp 125 volt appliance cord with a 15 amp 125 volt cord?
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
What wire size for 70 amp service at 240 volt?
4 copper
How do you wire 220 volt 200 amp diagram?
With thick wires that have excellent insulation.

What size wire in a 40 amp 12 volt circuit?
Use 8 gauge wire.
How do you check an amp wire for power?
test light or volt meter
What size wire for an 80 amp 220 volt circuit?
# 3 gauge

What size of 12v transformer will run 600watts?
Amps * Volts = Watts Amps * 12 = 600 600/12 = Amps = 50 amps You would need a reserve capacity, so I'd go somewhere between 60 or 100 Amp rated transformer. Transformers are rated in volt-amps which is usually calculated the same as watts. But the term "watts" technically does not apply to transformers. So you need a 600 volt-amp transformer or, as Redbeard has suggested, you need an 800 or 1000 volt-amp transformer. That's a lot of amps for a 12 volt system so I recommend you double check your requirements. You will need a #2 gauge wire if your requirements are correct.
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
What size wire for 25 amp 110 volt for 75 feet?
In the US and Canada, 10 Guage wire will suffice
What gauge wire for 240 volt 30 amp 55 ft?
10 gauge will work fine.
