IEEE 45-1967

IEEE 45-1967 is the recommended practice for electric installations on shipboard, defining guidance for marine electrical systems where power distribution, equipment selection, and installation conditions must work reliably in a demanding environment. As a transportation-focused technical document, IEEE 45-1967 helps address shipboard engineering concerns such as arrangement, protection, and serviceability of electrical installations. It is particularly relevant when consistent practice matters for safety, performance, and maintainability across onboard power and control systems.

IEEE 45-1967 overview

This standard provides shipboard electrical installation guidance for marine applications that require dependable operation under vibration, space limitations, moisture, and other service conditions common at sea. IEEE 45-1967 is intended to support sound engineering judgment in the design and implementation of electrical systems, including how installations are organized and protected. For organizations working with shipboard power, controls, and related equipment, it offers a technical reference for aligning practice with established expectations.

Typical use cases

IEEE 45-1967 is commonly used when specifying or reviewing electrical installations on vessels, including distribution arrangements, onboard wiring, protective measures, and the placement of connected equipment. It is relevant to ship construction, refit, and maintenance work where marine electrical systems must be installed in a controlled and practical way. The standard may also support procurement and engineering decisions for shipboard components, circuits, and systems that need to operate together reliably in transportation settings.

Why this standard matters

For shipboard electrical work, IEEE 45-1967 helps reduce uncertainty in design and installation practices by giving a common technical reference. That can improve compliance efforts, support safer installation choices, and make reviews more consistent across projects and suppliers. It may also help limit operational risk by encouraging installations that are better suited to marine conditions and easier to inspect, maintain, and service over time. For teams handling electrical systems on ships, that consistency can be valuable from both engineering and procurement perspectives.
