What is IEC 60092-402:2014?

IEC 60092-402:2014 is a technical standard developed by the International Electrotechnical Commission (IEC). It focuses on the electrical installations in ships and establishes requirements for the design, construction, and maintenance of electrical systems onboard.

Understanding the Scope

This standard applies to all types of ships, including merchant vessels, naval ships, and fishing vessels. It covers various aspects of electrical systems, such as power generation, distribution, control, and protection. The goal is to ensure safety, reliability, and efficiency in maritime electrical installations.

The scope of IEC 60092-402:2014 includes guidelines for:

Designing electrical installations

Selecting equipment

Installing cables, switchgear, and transformers

Ensuring proper insulation and earthing

Maintaining electrical systems and conducting inspections

Key Requirements and Benefits

Compliance with IEC 60092-402:2014 is crucial for shipbuilders, shipowners, and operators to meet the international standards for electrical safety at sea. Here are some key requirements outlined in this technical document:

Electrical Safety: This standard sets guidelines to prevent electrical hazards like electric shock or fire accidents. It emphasizes protective measures, grounding systems, and insulation requirements.

Compatibility: The standard ensures compatibility between the different components of the electrical system, promoting seamless integration and effective communication between equipment.

Reliability: IEC 60092-402:2014 addresses the design and construction of electrical systems to enhance reliability, minimizing the risk of breakdowns and failures that could lead to operational disruptions.

Maintenance: The standard provides guidelines for regular inspections, maintenance procedures, and testing protocols to keep the electrical installations in optimal working condition.

Environmental Conditions: Shipboard electrical systems are exposed to unique environmental challenges at sea. This standard considers factors like temperature, humidity, vibration, and corrosion protection to ensure system durability.


IEC 60092-402:2014 plays a critical role in ensuring the safety and reliability of electrical installations on ships. Compliance with this international standard not only protects lives and property but also ensures uninterrupted operations and reduces the risk of electrical failures onboard.

By following the guidelines outlined in this technical document, shipbuilders, shipowners, and operators can navigate potential electrical hazards and deliver maritime electrical systems that meet the highest global standards.
