The power to the garage door opener should be supplied by AWG 12/2 wire on a 20 amp breaker protected by a GFCI. The wire going to the sensors on each side of the door can be door bell wire.
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
You listed no gauge wire. This is the required breakers.14 gauge - 15 amp12 gauge - 20 amp10 gauge - 30 amp8 gauge - 40 amp
No - the two have no relationship to each other at all.
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.
The wire size depends on how much current it will conduct.

see American Wire Gauge. The larger the number the small the wire size.
16 or 18 gauge wire
Wire size is the gauge (thickness of wire) hazard is almost anything not wired correctly.
The nearest wire size is #6 AWG which is .162023.
on a 4000 watt amp the best gauge wire woul be between 2 and 0
No, the higher gauge means a thinner wire.
You listed no gauge wire. This is the required breakers.14 gauge - 15 amp12 gauge - 20 amp10 gauge - 30 amp8 gauge - 40 amp
#10 refers to the size in AWG (american wire gauge)
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.
Use 8 gauge wire.
It depends on the size of the hole your beeds have. Usually prefer I prefer to work with 22-24 gauge soft wire.
