Megger is used to test the resistance/insulation capacity
between two conductors be it
(*) Phase and neutral
(*) Line to ground.
(*) Phase to phase
For testing using megger

(*) Connect one terminal to the phase and other terminal to
neutral/ground for testing line to ground resistance.

(*) Connect one terminal to phase and other terminal to
another phase in case of phase to phase resistance.

All the nominal value of resistance must be greater than
atleast 1Mohm.
