26 AUG 2026 · 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.

19 AUG 2026 · In this episode of Campervan Electrics DIY, Jude breaks down the essential first steps for building a reliable 12-volt system that actually lasts through real-world weekends. Learn why skipping a proper load plan leads to fast battery drain and blown fuses, and how to calculate total daily amp-hour needs by listing every device, its current draw, and runtime. Discover the right sequence for connections, wire sizing to limit voltage drop below three percent, and fuse placement that protects your cables without guesswork.
Jude also covers adding a twenty percent capacity margin, grouping circuits for safety, and fitting a DC-to-DC charger based on your typical parking and driving habits.
Key takeaways:
- Always calculate total load before choosing any components
- Size wire for distance and amps to avoid dim lights or weak pumps
- Place fuses close to the battery and match them to cable capacity
- Add margin for unexpected loads and group heavy devices on separate circuits

11 JUL 2026 · In this episode, we break down the essential checklists every weekend campervan builder needs for wire sizing, fuses, and DC-DC chargers. Skip the guesswork that leads to voltage drops, overheating, and unreliable power—learn the exact steps to measure runs, match loads, and protect circuits from day one. We cover calculating cable sizes against 3% voltage drop tables, placing fuses close to the battery to match wire ratings, and installing DC-DC chargers with proper airflow, oversized cables, and dual fusing. These basics connect directly, so getting them right builds a system that works reliably from the start.
Key takeaways:
- Measure distance and max current first, then select wire from voltage drop tables
- Size every fuse just above expected load but below cable capacity—no shortcuts
- Mount chargers near batteries, replace thin factory cables, and test voltage under load
