If you have doubts about how to calculate the section of a cable, or you are looking for a cable section table according to power, you are in luck. We have found these specific tables for 12V, 24V and 48V that will solve any doubts you may have about how to calculate the section of a cable for your camper or caravan electrical installation.
In the following cable cross-section calculation tables you will find the column on the left (maximum amperes to be passed) and at the top of the table you will find the standardised cable cross-sections.
The cell that matches the row and the column corresponds to the maximum distance in metres recommended for that cable and current.
IMPORTANTRemember that the table cable cross section according to power is a recommended table of minimums. The ideal is to use the cable section according to the maximum power allowed by the device you want to install, consult its technical data sheet to check the maximum section and do not skimp on copper. If you have any doubts about how to use these tables, we have made a video explaining how easy it is; Video how to calculate the cross section of a cable
