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).
yes use 12 gauge for 20 amp or 15 amp outlets
if you want to save money you should use 14 gauge for lights but never put 14 gauge wire in a 20 amp circuit.
Yes. You can always use a larger gauge wire, just not smaller.
Yes, 15 amp rated outlets can be used with twelve gauge 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.
#14 copper wire is rated for 15 amps.
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).
There are many size gauge wires used in the making of an automobile, anywhere from 4 gauge to 22 gauge.

A voltage needs to be stated. Assuming the question is from North America 120 volts will be used. Assuming that the 800 watts is for each outlet that is a total of 2400 watts. The electrical code states that a conductor in continuous use can only be loaded to 80% capacity. I = W/E = 2400/120 = 20 amps. A #14 conductor is rated at 15 amps x 80% = 12 amps. A #10 conductor is rated at 30 amps x 80% = 24 amps. So to answer the question, no a 14 gauge wire and a 15 amp breaker will not handle 3 outlets using 800 watts.

Mainly in retail outlets
Yes, they can.
There are many size gauge wires used in the making of an automobile, anywhere from 4 gauge to 22 gauge.
Batteries provide Direct Current (DC) while household outlets provide Alternating Current (AC).
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.
the 12 gauge
A marking gauge is used in woodwork and metalwork. A marking gauge is used to highlight or plan out lines that will be cut along. It is also called a Mortise gauge.
