12 AWG.
Wire size is the gauge (thickness of wire) hazard is almost anything not wired correctly.
Wire size 0000 AWG is the largest electrical wire. It is 0.46 inches in diameter or 11.86 mm in diameter. The cross sectional area is 107.16 mm(squared).
Use AWG #6 wire.

I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
Wire sizing is based on the amperage of the connected load. The wire size number 12 is rated at 20 amps.
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.
Both 12-2 and 14-2 wire have 2 wires in a single cord. Neither contains a ground wire. Size 12 wire is a larger wire than size 14 wire. Size 12 wire can carry more amperage without getting hot and burning up. They would not be used for house wiring or machinery since they do not have a ground wire.
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
