Simply remove the soft-rubber caps attached to the breaker, push the breaker into the enclosure (snap-fit), then install the cover (snap-fit). No hardware needed!

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 🙂

Inspiration & Idea

Exposed components (shunt, battery terminals, breakers, etc.) in our campervan make us feel a bit uncomfortable due to the risk of short circuit. Here’s why…


Before installing the electrical system in our new van conversion, we are slowly working on designing and making enclosures and covers for the components we plan to use:


It’s still a work in progress at the time of writing these lines, but we’ll add more to our Store as we go… Here is what we have so far:


  • Ships From:  British Columbia, Canada.
  • Carrier: Canada Post / USPS.
  • Cost: Actual carrier shipping rate calculated at checkout. You can combine other items from our Store to save on shipping.


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 about 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.

You all out did yourself with the design and implementation of the circuit breaker enclosure. 1. Having relocatable cable lug port coverlets. (Now I wish BlueSea would do something similar for their m-Series battery disconnect switches rather than having to permanently break a tab off.) 2. Having the base ‘snap’ into the back of the circuit breaker (Pure elegance, the marketing department would call that a ‘surprise and delight’). 3. Tolerances, everything fit perfectly. 4. Having the front snap in rather than using a fastener, again pure elegance. Thank you for demonstrating that refined design can still be found.

  1. Got two , one for each of my transits CCP .Have not installed yet. Delivery was super prompt. Well packaged.Seems like it will work exactly as expected. Also nice to support a great contributor to the van world.

    • Thanks Edward, much appreciated! 🙂

  2. Elegant solution to a serious potential hazard.

  3. Safety is important with electricity, and this enclosure fits the need.

  4. Nice work on the circuit breaker case. I received it today. Thank you!

  5. Got ’em. Good to go

  6. Received in good order – great quality and the enclosed contacts will help avoid electrical shorts from dropped wrenches, etc

  7. Cover works perfectly.

  8. Only one problem: the 285-series breakers come with little soft-rubber caps to cover the terminals. The enclosure seems not to fit when those caps are in place. Remove the caps, and the enclosure lid fits fine. I may have used a bit too much force on the lid, to try and make it fit. Now that the caps are gone, no problem.

    • That’s correct! The small soft-rubber caps have to be removed. They are no longer required since the enclosure completely protects the breaker.
      The product photos show the breaker without the rubber caps, but I’ll add some text to clarify as well 🙂

      Thanks for your support,

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. Every day is an opportunity for a new adventure... We’re chasing our dreams, and hopefully it inspires others to do the same!
