If you have to ask here, you shouldn't be trying to wire in a 20A compressor. You will require a special circuit for the voltage and current with an independent breaker.
Check your local code for the wire size or talk to a qualified electrician.

∙ 10y agoNormally a AWG #10 wire on a 30 amp breaker will suffice. But check the compressor owners manual to make sure.

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 of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt
What is the wire size for 208 volt?
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
What wire size is needed for 415 volt 20hp compressor motor?
A motor can be reckoned at 1.6 kVA per horse-power, so on a 415 v 3-phase suppy the current for 20 HP would be 45 amps. For continuous use the wire size should be 25 mm2
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
Will splicing a 3 wire 240 volt compressor with a 4 wire 240 volt male end damage compressor motor?
It could if you don't get the terminals and motor wires on the correct terminals.

AWG #3 copper.
What size wire do you need for a 200 Amp 240 Volt 3 phase 4 wire service on a doctors office?
You might be out of luck. Three phase delta 240 volt services are a thing of the past. As far as I know there never was a 240 volt three phase four wire. The line to neutral voltage would be 240/1.73 = 139 volts which is of no use to anyone. Three phase four wire system for business and commercial use these days is 120/208 volts. A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.
On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
How do you hook up 3 phase to a 10 hp compressor?
First you have to have three phase power coming in. 3 phase are three hot wires working together on a syne wave. If you have 3 phase coming in, hook the three hot wires into the compresser, if it runs backwards, trade places with two of the wire and let the third one alone and you should be running.
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
