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.

The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
No, using the AWG system of measuring wire sizes the smaller the wire numbers go the larger the wire size becomes. Hence the number 14 is smaller that the number 16 so it is largest in size of the two wires.
For a 240 volt, 50 amp circuit, you typically use a minimum of 3/4 inch conduit for copper wire and 1 inch conduit for aluminum wire, assuming you are using THHN or THWN wire. The specific size may vary based on the number of conductors and any bends in the conduit. Always consult local electrical codes and the National Electrical Code (NEC) for precise requirements and adjustments based on your specific installation conditions.
The wire fill chart in the NEC provides information on the maximum number and size of wires that can be safely installed in a conduit or raceway, helping determine the appropriate wire size for electrical installations.
The recommended wire size for a 220v electrical circuit is typically 10-gauge wire.
The recommended wire size for a 240V electrical circuit is typically 10-gauge wire.
The recommended wire size for a 50 amp electrical circuit is typically 6-gauge wire.
The recommended wire size for a 125A electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 200A electrical circuit is typically 2/0 AWG copper wire.
The recommended wire size for a 220-volt electrical circuit is typically 10-gauge wire.
The recommended wire size for a 50 amp electrical circuit is typically 6-gauge wire.
On the wire itself? It'll have the type of wire as well as the size and maybe the manufacturer part number.
The recommended wire size for a 75 amp electrical circuit is typically 6 AWG (American Wire Gauge) for copper wire.
The recommended wire size for a 90 amp electrical circuit is typically 4 AWG (American Wire Gauge) for copper wire.
The size of wire you need for your electrical project depends on the amount of current the circuit will carry. Consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific project.
