But be very careful: before you can get proper advice about the right size wire to use you have to include information about the length of run and the intended installation method!
Is it to be hung between buildings in the open air or fixed to a wall, etc. ... ?
Is it to be in a conduit or clipped to a cable tray, or is it running underground, etc. ... ?
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
What size wire for 100 feet 20 amp circuit to run pond fountain?
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
What wire size is needed for 15 volt circuit?
The wire size depends on how much current it will conduct.

Is American Wire Gauge a standard used to describe the size of a wire?
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.
Explain the rules for GFCIs in bathroom wire size wiring?
NEC states that all GFCI's require a 20 amp circuit, the wire size for a 20 amp circuit is 12 gauge.
What wire size is needed for 15 volt circuit?
The wire size depends on how much current it will conduct.
What is the use of wire gauge?
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.
What is the maximum breaker size for these gauges wire?
You listed no gauge wire. This is the required breakers.14 gauge - 15 amp12 gauge - 20 amp10 gauge - 30 amp8 gauge - 40 amp
How big is 6 gauge wire?

What size wire do you use on a fridge freezer?
12 gauge wire is used for household plugins, and 14 gauge wire is used for lights. So, 12 gauge is the size to use. But since a freezer has an electric motor, it is best to not plug anything else with a motor into the same circuit.
