ISO 16315:2026

This document specifies the design and installation of alternating current (AC) and direct current (DC) electrical systems used for the purpose of electrical propulsion and/or the electrical part of a hybrid propulsion system (system with both a rechargeable battery and a fuelled power source).

This document is applicable to electrical propulsion systems operated in the following ranges either individually or in combination:

• direct current of less than 1 500 V DC;
• single-phase alternating current up to AC 1 000 V;
• three-phase alternating current up to AC 1 000 V.

This document is applicable to electrical propulsion systems installed in small craft up to 24 m length of the hull (LH in accordance with ISO 8666).
