When using a Megger to test for grounds in a scenario involving conductors within a metallic conduit, the correct procedure involves connecting one lead of the Megger to each conductor (red and blue) individually and the other lead to the conduit. This method checks for insulation breakdown or faults between each conductor and the conduit, hence both A and B are correct approaches.
