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.
In North America there are about four different sizes used. A #14 wire is rated at 15 amps and is used for basic wall outlets and lighting. A #12 wire is rated at 20 amps and is used for dedicated circuits for hot water tanks, appliances and kitchen counter outlets. A #10 wire is rated at 30 amps and is used for the clothes dryer. A #8 wire is rated at 40 amps and is used for an electric range. These are the four most common size cables used in home construction wiring for power distribution.
30 amps is often the limit recommended for standard residential wiring on a #10 copper wire. You are correct.
Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.
In residential wiring applications the most used is 14 gauge wire for light switches as long as the circuit breaker or the fuse is 15A. If your lighting circuit is on a 20A fuse/circuit breaker then you need to use 12 gauge wire
The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
The most common wire ran in 120v residential is NM (Non-metallic) sheathed wire such as the brand Romex. 14 gauge wire generally has a white sheathing and can be used on 15 amp circuits such as lighting. 12 gauge wire is thicker, generally having a yellow sheathing and can be used on 20 amp circuits such as those serving receptacles. Considering future demands, 12 gauge wire should be used. Under no circumstances should you ever use 14 gauge wire on a 20 amp circuit.

The correct GAUGE wire is 28 for a car stereo.

Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
It is not difficult at all. It needs 14 gauge wire, freely available any hardware store.
Wire gauge is determined by the capacity in amps. At 120 volts it requires 8.33 amps to provide 1000 watts. The typical residential application would require 18 AWG wire 1.024 mm in diameter.
The American Wire Gauge (AWG) is a shorthand way to identify key characteristics of the size of a wire and pertinent specifications associated with the size. So you will often hear someone ask what gauge wire do I need for a 15 Amp circuit in my home. The shorthand answer in this case would be 14 AWG for a typical residential wiring job.

You can pull 10 #3 gauge wires in a 2 1/2" conduit.
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
