Humbuckers have two coils, to "Tap" means to only use One of the coils, therefore the other coil is effectively left out of the circuit. The one that's not in the circuit isn't cut to earth, it's just open and doesn't/cannot, form a circuit. When you "Tap" them, you can wire a switch in a circuit so you can actually select either of the coils or both. This is often called coil cutting (where Joe is getting confused) but coil cutting and tapping are both the same. You can't possibly "Tap " a single coil pickup as there are only two wires coming from it. What on earth would you "tap" into ?????
