Neutral: The white wire is called the neutral wire. It provides the return path for the current provided by the hot wire. The neutral wire is connected to an earth ground. Ground: The bare wire is called the ground wire.
WebUnless one of the wires has continuity to the transformer core, the polarity doesn't matter. A relatively safe way to test transformers is to hook up a small AC voltage (1-5VAC) and measure the voltages across the other windings. Share. Cite. Follow answered Dec 17, 2010 at 20:38.
