HV Exit Exam • Set 2 Question 7 of 30

What safety enclosure rating (IP Rating) is required for High Voltage marine switchboard cubicles?

✓

Direct Answer

Option D: IP2X minimum (protection against touch) up to IP44/IP54 for splash protection

IEC 60092-503 mandates specific IP ratings for HV switchboard enclosures to prevent accidental contact with live parts. An IP2X rating provides the minimum required protection against solid objects, while higher ratings like IP44 or IP54 are necessary in engine room environments to protect against moisture, dust, and splashing, ensuring long-term insulation integrity.

All Options

IP00

IP10

No rating

IP2X minimum (protection against touch) up to IP44/IP54 for splash protection (Correct Answer)

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • High Voltage Safety Officer & Switchgear Operations (HV).
