It'd depend on how much current the transformer would have to carry. Some would require 14 ga, some would get by with less, some would require more.
A domestic D/W uses 14 gauge wire.
It is better to use 16 gauge or 14 gauge speaker wire for your home theater applications.
14 AWG.
You should never try to use more than 15 amps through a 14 gauge wire.
no
it is not recommended because the 14 gauge wire is not capable of carrying the same amount of load as the 12 gauge wire which could result in a fire.
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.
For the best performance I wold use at least a 14 gauge wire.
No. A 20 amp breaker needs 12 gauge wire.
The gauge of wire that is 12 volt is 18, 14, and 16.
The larger the wire gauge, the smaller the diameter. 12 gauge is bigger than 14 gauge.
14-3 Is the standard wire use for residental smoke detectors.
