Wire size calculator online
Calculate the required cable thickness easily with our cable calculation online. Free to use, directly online. Simple for mobile and desktop. The cable calculation can be saved directly as a PDF. The calculations are an estimate based on the nen1010 tables, always check the datasheets and specifications of the materials used.What effects cable thickness?
The following parameters affect the cable size:• Cable current affects the thickness.
• Cable length affects the thickness.
• Mounting method affects the thickness.
• Multiple cables affect the thickness.
• Insulation type of the cable affects the thickness.
All of these factors are configurable in the calculator, so take them into account when performing the calculation for the correct result.
For who is this cable calculation suitable?
Currently the cable calculation software supports: copper cable, different mounting methods, single phase (230v) and 3 phase (400v) low voltage.What devices does the calculator support?
The cable calculation has been specially developed for devices with a continuous high load, so the above devices are suitable for this. Many of these applications use a ground cable, which can also be calculated with the option "directly in the ground"The calculator is specialized for the following devices:
• Solar inverter
• Charging station
• Heat pump
• Air conditioning
• Storage batteries
• Home battery
How is the calculation performed?
The software uses nen1010 reference tables in combination with "derating" in case of several cables against each other. This results in a highly accurate and safe result.Why this cable calculation software?
Our cable calculation works without multiple click-through screens, complicated codes, as is the case with tkf cable calculation, Draka cable calculation, Nexans and Intelec. In addition, the software is automatically up to date with the most recent standards and rules.The cable calculations and cable thickness table are also easy to read with the chosen mounting method. Overall one of the best and most easy solutions out there!
