To keep the voltage drop in the cable as low as possible and to avoid unwanted cable heating, it is necessary to carefully determine the required cable cross-sections. The voltage drop between the power source and the consumer must not exceed 10% (1.2 V at 12 V). In addition, please note the following:
Since the current is fed back and forth via 2 cores, the conductor length is always the same as the cable length. In a circuit, the voltage source and the consumer are connected via a plus and a minus cable. To calculate the cable length, the total cable length is required, i.e. the length of the positive AND the negative cable. The specific resistance of copper is 0.0164 (Ω x mm²)/m.
mm² (due to the maximum current carrying capacity)
mm² (due to the maximum voltage drop)
Cables with this cross section are not available in normal specialised trade.
We recommend a cable with at least mm² Cross section
We recommend a H07V-K cable or preferably as a tinned stranded wire
The cable calculator is valid according to DIN EN ISO 13297 for max. 3 bundled and exposed single wires (with 70°C insulation classification) at 30 °C ambient temperature. Please note that special regulations apply to cable routing in the engine compartment and therefore other cable cross-sections are required.
Single-core, flexible H07V-K control cable according to DIN 72551. Suitable for the installation of lighting equipment, signalling equipment, engine, pumps, electrical accessories and other equipment. Seawater-resistant PVC insulation. Temperature range -40° to 105°C. Available in red or black. Price per metre.
Note: The indicated outer diameter values are approximate values, minimal deviations possible.
