Find the right wire gauge for your van conversion 

Use this calculator to find the right wire gauge for your van conversion's electrical system.

📝 Note: This is specifically for Jotun paints — the two types recommended for protecting your van conversion: Jotun 87 and Jotun 90. Either is fine for heavy-duty underside protection of the whole van.

We go over designing your electrical system in my van conversion course. The 'Electrical System' chapter walks you through the whole process start to finish. Enjoy :-)
