A. It's 240 volts & B. Wire size is a function of amperage. 12-gauge wire is used with 20 amperes or less. So, 12-gauge wire can be used with 120V/20A or 240V/20A. Keep in mind though that 240V in the U.S. has 2 live 120V lines so if you encounter a white wire, it's probably an unmarked live & should be repainted as black or better yet, red (to indicate the 2nd live wire).
Most small old houses only have a 100amp service panel, 4-5 bedroom, very large houses have a 200 amp panel. Now a days,with a small house, you should have a min of 150amp panel installed. To answer you question, there is a main service panel calculation that is used,and goes by the house as to get a service that will pass codes.
For general residential outlets, 12-gauge Romex is commonly used. This wire size is capable of handling the typical load requirements of outlets in homes. Make sure to consult your local electrical code to confirm the appropriate wire gauge for your specific installation.
AC, alternating current is used to power electrical outlets in the U.S..
Wiring is measured in AWG (American Wire Gauge) in North America.Sometimes it's designated with the number sign in front, such as14 gauge or #14 wire.The smaller gauge numbers, mean larger diameter wire. So #10 wire is thicker (and can carry more current) than #18.From The Home Depot Wiring 1-2-3 book, here are some typical gauges used in homes:For copper wiring: 10 gauge wire is rated for 30 amps, 12 gauge rated for 20 amps & 14 gauge wire rated for 15 amps.A wire going to a small appliance many times is 18 gauge. Telephone wire is smaller (I think 24 gauge).
120 va on a 120 v socket means you can draw up to 1 amp from the socket. The number of outlets/sockets depends on the amp rating of the circuit. If it's 10 amps you can definitely have ten sockets and your local wiring regulations might allow more, on the basis that they won't all be used at once.
For outlets, it is recommended to use 12-gauge wire for 20-amp circuits and 14-gauge wire for 15-amp circuits.
14 gauge wire is commonly used for general household electrical wiring, such as lighting circuits and outlets. It is suitable for carrying moderate amounts of electrical current safely.
In Argentina, the most commonly used electrical outlets are Type C and Type I. Type C outlets are the standard European two-prong outlets, while Type I outlets are three-prong outlets commonly used in Australia and New Zealand.

In Brazil, the power outlets commonly used are Type N outlets, which have three round pins in a triangular configuration.
In Argentina, the most commonly used electrical outlets are Type I outlets, which have three flat pins in a triangular configuration.
The most common types of wall outlets used in residential buildings are the standard two-pronged outlets and the more modern three-pronged grounded outlets.
