For USA, Canada and countries running a 120/240 volt 60 Hz power supply service and also for countries in Europe and other world areas running a 230 volt 50 Hz power supply service.
There is no conversion, wire size is based on the load current of the circuit. It is stated in the electrical code books what the maximum capacity of each conductor size will allow. The voltage is independent of the wire size. When discussing voltage it is the insulation factor that you have to be concerned about. The applied voltage to a wire should never be more that the insulation factor. Common insulation voltages of most used wires are 300, 600 and 1000 volts.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
What is the proper size wire cord for a 12 amp vacuum sweeper 120 volt?
16 gauge is rated at 13 amps, but I would use 14 gauge which is rated at 15 amps just to be safe.
What size aluminum wire to feed 125 Amps 220 volt a distance of 175' and what size ground?
A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.
What size wire do you need for a 208 volt 3 phase load that draws 10.5 amps?
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
What size wire do you need for 15 amps?
AWG 10.
What size wire is required for a 220 volt at 54 amps?
6 AWG
What wire size is used for 100 watt 12 volt lamp?
Volts * Amps = Watts 12 V * ?Amps = 100 Watts OR ? Amps =100W/12V OR 8.33 Amps = 100W/12V Use a 10Amp fuse inline and you can get by with 16Ga wire.
What wire size 240 volt 21 amps 150 foot run?
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
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.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps
What size wire is used for a 220 volt dryer?
For a standard clothes dryer, new homes are roughed in with 3C #10 cable which is rated at 30 amps.
What is the proper size wire cord for a 12 amp vacuum sweeper 120 volt?
16 gauge is rated at 13 amps, but I would use 14 gauge which is rated at 15 amps just to be safe.
What size aluminum wire to feed 125 Amps 220 volt a distance of 175' and what size ground?
A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.
What size wire do you need for a 208 volt 3 phase load that draws 10.5 amps?
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
Does a double 30 amp breaker mean you have 60 amps for a 220 outlet?
breakers are rated by wire size, not voltage. the appliance manufacturer will probably specify amperage.
What size feeder wire for 100 amps?
Service wire for 100 amps requires AWG #3 copper.
