In this episode of Campervan Electrics DIY, Jude tackles the common sticking point of sizing wires for a DC to DC charger install. Many weekend builders guess at cable gauges only to face voltage drop, warm wires, and slow charging. Learn the practical process of calculating voltage drop first using your exact current draw and full cable length, then selecting the right fuse and verifying the return path for safe, efficient performance.

Key takeaways:
- Measure total cable path including returns and bends before choosing wire
- Apply the voltage drop formula to stay under 3% loss for reliable charging
- Match fuse rating to wire capacity, placing it close to the power source
- Factor in total system loads and split circuits when needed to avoid overloads
- Use real examples like a 40-amp charger on a 15-foot run to compare 6-gauge versus 4-gauge options

These steps replace trial-and-error with confident planning tailored to weekend builds.
