The megger applies a very high DC voltage across two conductors to ensure they are properly what?

Explanation:
A megger tests insulation resistance. By applying a very high DC voltage between conductors (and between a conductor and ground) it stresses the insulation and reveals any leakage paths. When insulation is good, only a tiny leakage current flows, so the measured resistance is very high, meaning the conductors are properly insulated from each other and from earth. If insulation were compromised, leakage would increase and the resistance would drop, signaling insulation problems. This device isn’t checking grounding, termination, or a direct short; it’s confirming insulation integrity.
