    Hello! There are several ways that you can determine the ground wire in the wiring. To get started, try to determine the color. The ground wire is usually yellow-green or green. If there is no color coding, then you need to use a multimeter. Set the ac voltage measurement mode on the tester, and then, with probes, check each pair of conductors, if there are 3 of them (ground, phase, zero). There should be no voltage between the ground and ground wires. When you find ground and zero, using the remaining phase you can determine which ground wire. To do this, first measure the voltage between the phase and one conductor, and then between the phase and the other conductor. In the bundle in which the voltage will be less, it will be grounding.
