    1. Dear there are two main types of kWh meter which single phae and 3 phase. In single phase we have 4 point in which 2 points for incoming service line and other two for out put. In 3 phase kWh energy meter we have 8 terminals in which 4 for incoming service line supply and 4 for the out put to load.
      In three phase 4 wire system wire is called 4 core or 5 core cable, in which red yellow, blue for L1 L2 L3 (Hot wires) and the black color wire for neutral and if the electric cable is 5 core the green wire for earth or ground.

      In you want to learn it completely about kWh meter connection then just serch in our we website search kWh and you will find the tutorials. And I hope these article / tutorials will help you to understand it.....
