4.2 Electrical system generator
The generator, automatic voltage regulator and circuit breaker are completely pre-wired.
The generator set is equipped with a CEEform socket to hook up the ship’s power supply system to the generator with
the supplied plug.
Depending on the generator output voltage the plug can be:
- P+N+E (unbalanced single phase with neutral),
- 2P+E (balanced single phase),
- 3P+E (3 phase without neutral), or
- 3P+N+E (three phase with neutral).
Current rating of the plug and socket is accommodated to the maximum output current of the generator.
Use a cable with wires with sucient cross-section for the maximum current:
Based on commonly available cable with wires with an insulation temperature rating of 85-90°C use minimum cross-sec-
tions as per table below.
Note a de-rating of 0.82 for an engine room temperature of 60°C and a de-rating of 0.7 for a cable with 4 to 6 wires has
been applied.
