A 240-volt, 2-hots-and-a-ground electrical system is commonly used for larger home appliances such as ranges, dryers, and air conditioners. It consists of two hot wires carrying 120 volts each (for a total of 240 volts) and a ground wire for safety. The two hot wires provide the higher voltage needed to power these larger appliances.
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.
12-2 wire typically carries 120 volts in residential settings and 240 volts in certain appliances or systems that require higher voltage.
P = E x I P = 240 x 2 P = 480 Watts
Amps * Volts = Watts So, Watts / Volts = Amps 2000 / 240 = 8.333 Amps You should run the circuit on a two pole 15 Amp breaker, using 14 AWG, 2 conductor (plus ground) wire, just so you have a little safety factor in the circuit size.
A 60 amp 2-pole breaker can handle up to 14,400 watts (60 amps x 240 volts). This is because a 2-pole breaker provides 240 volts, which is the typical voltage for larger appliances and machinery.
2 prong is a hot and neutral and a 4 prong is a 3 phase with a ground wire.3 pole 4 wire meaning 3 hots could be 240 volts or 480 volts

voltage is the PUSH on electrons seriously 120 volts is the difference of 240...Simply said 240 volts is 2 times as strong as 120 volts.
The standard voltage conversion ratio from 240 volts to 120 volts is 2:1.
240, single phase for houses208 3 phase for comerical property, can be single phase.480 volt for industrial property or 660 volts,all 60 HzUSA calls it single phase but there is actually 2 hot leads coming into the house with a natural and a ground.It is actually two 120 volt 'hots' which are 180° out of phase from each other. Voltage between either of these and ground will be 120 V. Voltage between the two hots is 240 volts. It is single phase because it is pulled off one of the phases from 3-phase, then a center tapped transformer gives the two 'opposite phases' (ground/neutral is off the center tap)In Vietnam we have 440 volts, 3 phase, 50 Hz on the poles.They bring in one hot wire and one ground. I call this single phase,It equals 220 volts in your house.
12-2 wire typically carries 120 volts in residential settings and 240 volts in certain appliances or systems that require higher voltage.
On the three prong 240 v receptacle there shouldn't be a neutral because it's not needed. Should be two hots and the ground and tuck neutrals in box.
P = E x I P = 240 x 2 P = 480 Watts
240 watts at 120 volts requires 2 amperes. Power = voltage * current
hire an electrician there is a national electrical code that must be met and this is a minimum and local code may be different and much more specific. if it is a hobby shop for the family out in the garage/ shed/ "barn" and only one machine is used at one time, looking at the voltage and amperage of every machine, use the highest voltage of each machine and note the highest one. do the same with each machine in amperage, note the highest. 240 volts will need 3 conductors and a ground (2 hots + 1 neutral + ground) 120 volts will need 2 conductors and a ground (1 hot + 1 neutral + ground) 200 amps 3 ought + #6 SOLID GROUND 100 amps #2 + #1 ground 50 amps #8 + #10 ground 30 amps #10 + #12 ground 20 amps #12 =#12 ground

the bare copper is always a ground
