Preferably lay all your cables before laying floors or insulation – they don’t need to be connected at either end.We opted for 3 sizes in our van conversion (small – 2.5mm², medium – 6mm², and large – 70mm²), covering all bases.It’s usually more cost-effective to buy and use a larger wire than every exact size. Go up a higher current rating rather than a lower one wherever possible. Consider standardising your cable sizes and connectors.It also makes fault finding more difficult. Any cables outside the van could be damaged by road debris, insulation might get broken, and any water ingress may cause cable corrosion. Always aim to keep your cable runs inside the van.You may need to compromise on the design when trying to get the shortest runs. We’ll cover this in more detail further into the article, but aim for the shortest cable runs for each circuit. Pay careful attention to your cable runs.Don’t forget to include where you’ll install the batteries, fuse blocks, switch panels, bus bars, and earth point. Detail exactly where they’ll be physically located in the completed build.Have a detailed list of every electrical appliance, device, and socket you want to install.Here are our top tips for getting started with the wiring: It will also ensure easy access to the electrical looms throughout the build. So, because the electrical part of the build will start early and finish late, having well-thought-out plans is key to avoiding re-work. Some of the last components to install in the conversion are electrical appliances such as reading lights and fridges. You will likely want to hide the wiring behind walls, lining, and furniture. If you have the luxury of starting a van conversion from scratch, you can plan every aspect of your build while stripping it out. When To Start Your Campervan WiringĬamper van conversions are big projects, so at what stage of the build should you start the electrical installation? The rest of the article is in-depth, so we’ve numbered each heading to help keep you on track. This article focuses solely on wiring a 12v campervan electrical system from the battery to the appliances. Instead, we have separate articles on how to wire the supply side and the battery bank: In this post, it would become unwieldy if we included how to wire every aspect of a system’s supply, battery, and load. Some conversions include AC circuits that run from the mains, bypassing the battery bank altogether. You can charge the battery from a mains supply. Others have massive solar arrays and can charge the battery from their engine and generator. For example, some people only have a small solar panel. You don’t need to install every method of generating electricity in your camper. The load side comprises various AC and/or DC circuits and how we use the electricity generated and/or stored in the battery bank.The battery bank is how we store the electricity generated so we can use it later, and.The supply side is how we generate electricity – solar panels, shore hookup, a generator, and the camper’s alternator,.Plus, we’ve provided a definitive list of the tools, resources, and materials you need for the job.Īn Introduction To Our Campervan Wiring GuideĪ camper’s electrical system is fundamentally made up of three core components: We end with a step-by-step guide on how to wire your campervan electrical system. We’ll discuss wiring in detail, including calculating wire sizes and tips for installing cable runs. We’ll start with the basics, explaining each component, why you need it, and how to choose the right one. This post is the complete guide to every aspect of campervan wiring. And all that knowledge will help with future maintenance and troubleshooting when you run into problems on the road. Understanding the components of a campervan electrical system is critical to a safe installation. But then it’s time to get it all installed and whirring. The first step is figuring out exactly how you’ll charge your batteries and buying your campervan appliances. It’s the beating heart of your lifestyle. It isn’t just about getting suitable batteries and fitting a few solar panels on your roof. The electrical system is probably the most significant and complex task of all. Undertaking a DIY camper van conversion project is quite a challenge. You can wild camp and boondock, taking advantage of glorious views, and still chill a beer or two. The need to recharge batteries at expensive campsites dwindles. With the proper setup, off-grid living can become a reality. Ready?Ī campervan electrical system is a lifeline to van living. You’ll have everything you need to know about campervan wiring, from the basics all the way up to more advanced concepts. With this guide, you can wire your camper like a pro. This is the ultimate guide to campervan wiring.
