Real World Application (FOrd Transit CCP2 Alternator Charging)

In our wiring diagram, there is a breaker between the DC-To-DC charger and the starter battery (see the red arrow below):


Per ABYC E-11 standards, breakers should be installed 7 inches from the charge source (measured along the wire). So we created an enclosure that allows us to install the breaker within that distance from the Ford Transit CCP2 (which is rated for 175A). Our electrical system is not done yet so there’s not wires in the photos below, but you get the idea 🙂

Do It Yourself.

We couldn’t find a way to safely mount surface circuit breakers in our van, so we made one.

This is an homemade product.

Each enclosure is individually 3D printed, takes over 2 hours to complete, and requires manual labor. This is not a mass-produced product. This is a crafted, hand-made product.

Low Volume.

We created this product for our own needs, to make just a few units. There is no way for us to ramp up the production and lower the price, unless we take it to injection molding manufacturing but that’s a whole another level we’re not considering at the moment.

  • Ships From:  British Columbia, Canada. Typical delivery time to USA is 2 weeks (more or less).
  • Carrier: Canada Post.
  • Cost: Calculated at checkout (actual shipping cost).

About us



Hello! We’re Isabelle and Antoine 🙂 In 2017, we sold our house (and everything in it), quit our engineering careers, and moved into our self-built campervan. We’ve been on the road since then, and every day is an opportunity for a new adventure; we’re chasing our dreams, and hopefully it inspires others to do the same!
