Review connector creepage and clearance using actual insulation paths, material evidence, environment and assembly details. Know what to request before approval.

Specify a connector insulation resistance test with clear sample identity, measurement paths, conditions and acceptance rules. Distinguish it from voltage proof.

Read connector current derating curves correctly. Check ambient temperature, loaded contacts, conductors and test conditions before approving a current rating.

Compare connector keying, polarization, latching and pinout. Check drawing views, mating references and coded variants to prevent incorrect connector pairing.

Understand connector mating-cycle ratings, test conditions, operation counting and service planning. Use a practical evidence checklist before selecting a connector.
