3/G wire has a black , red , white , and bare .
2/G wire has a black , white , and bare .
110-125 uses the black from 1 or the other power busses the white returns to the neutral buss often shared with the ground which returns to earth while the white returns to the generation source via the line .
220/240 3 wire uses the black and red 1 off each buss , white and ground as above .
220/240 2 wire alternates with each line being either a hot or neutral at 180° separation in turn , allowing for a ground neutral and the appliance is directly earth grounded . A/C does this 50-65 times per second , 60 as a US standard .
The bare ground is actually safety device that resulted from the use of the electric chair . When the voltage reaches a point where the cycles and electron fields over lap the neutral looses it ability to carry the full return volume . This resulted in adverse effects from a little tickle to burns and worse . Adding the direct earth ground give the over load a place to go and a fault safety where the neutral is disrupted .
