Cable for Boats

- The correct cable width is essential -

In order to keep voltage drop in cables as low as possible and to avoid over heating, you should carefully investigate the required cable cross-sections. The voltage drop (loss) between power sources and consumers must not exceed certain values.

The maximum permissible voltage loss of navigation lights is 5%, which is 0.60 V for a 12 V vehicle electrical system. For other consumers, the voltage loss is 7%, which corresponds to 0.84 V for a 12 V vehicle electrical system.

The required conductor cross-section, wherein the permissible voltage drop (V) is not exceeded, is calculated as follows: Since the current is multi-directional and it has 2 cores, the conductor length is twice as large as the cable length (the distance between the consumer and battery). The constant 56 = conductivity of copper.

At SVB you can have cables made to measure. Let us help you realise your vision. We are happy to help!
