We talk about protecting your cables with PVC flexible conduit. We show you how to wire basic 12volt circuits for your camper van build, including wiring lights in parallel, wiring light switches, cable sizing and fuse sizing. We also chat about Watts Law and how we can use it to work out our system electrical loads. If you have any questions or suggestions for future videos please leave them in the comments sections below and I’ll do my best to get back to you as soon as I can.

@Greg Virgoe hi Greg just to confirm did you fit a split DC to DC charger?
@Bisho Khan where in USA. Expat from Michigan living in England past 17 years
Gosh that was helpful! Thanks for sharing all that! Really appreciated and helping out the noobies like me out there! Cheers Greg
@Jeremy Dubrulle you are welcome. Glad you liked it 👍🏼😃
Best channel…Hands Down. Props Greg and a HUGE Thank You 🙏
I am currently in the planning stages of my first build; the power of it all is what has me so intimidated. I am so thankful for this video, you didn’t just say do this – use this, but rather took the time to explain why so we can easily adjust for our use. Your detailed explanation will also help us troubleshoot down the line if we run into issues or decide to add or upgrade a load.
Thats great that you found it to be useful, I had to increase the size of my own wiring recently because we have added further things to our 12v system. So it does help to know how it all works. I have an essential playlist of camper build videos that may be of use to you here is the link https://youtube.com/playlist?list=PLLhAyWhGGbi4nOabmpkLMGvfLGox2ljp_
Also a great source of help for sizing cables is the handy online calculator on this webpage. you just put in your info and if the result is green your good to go.

hello, do I need a fuse between the solar panel and the solar mppt charger? the distance between them is 3 to 4 meters. I’m using 20Amp mppt and 150watt solar panel.
It is best to have one fitted and the perfect solution is this MC4 fuse from Renogy here is a link https://amzn.to/3V2s0CW
@Greg Virgoe thank you
Just came across your channel and I am VERY impressed.
Well done and looking forward to watching them all now.
Cheers from South Australia 🇦🇺 👍
Awesome, thank you! and hope you find them all very useful too.
another fantastic video ive found, one thing im still unsure on is cable sizes. why did the lights needs 1.5mm when from the table 1mm would have been plenty. also 2.5mm (according to the tablew) for the usb sockets was plenty big enough. cheers
There’s no harm in going a little bigger on cable sizes in fact there will be less voltage drop if you do. I could buy a reel of 1.5mm cable and wire most things so it was easier. 👍🏼😊
Thank you for this video. Made complete sense.
However, can you do something which instead of a standard battery, create a wiring diagram for a powerbank (Bluetti AC220Max). I want to run my camper off that to power12v fridge, 6 led lights, and several USB port locations. Plug sockets, water pump and also having the campsite incoming power, solar power and car charging capabilities.
Absolutely great, Greg. Your videos give me complete reassurance and your delivery style makes any job feel within reach and achievable. Thank you 🙂
I think if you break the tasks down into bite size chunks it makes it more manageable and you get little mini goals when you complete each stage 🤩
Hi Greg, this has help a lot although I am still scratching my head. I’m your pdf you have the solar panels using 4 mm cable and also the fridge using 4 mm cable. Please can you confirm the fridge is running 4 mm. Many thanks.
A lot of compressor fridge do not work if there is a slight voltage drop so the supply cable needs to be oversized. I used 6mm cable to supply our fridge in the van. The manual will back that up. 👍🏼😊
Thank you so much for making it easier for us
No problem 😉 happy to help 👍🏼
Just what I’ve been looking for Greg – thanks so much! Clear, concise, really helpful. Currently revamping an old caravan in Outback Oz, so not easy to find info other than online. Top job👍
Awesome I’m glad you liked it. There are a few handy videos here on the channel like that. Good luck with your project. 👍🏼😎
I have a question, in my system I have a 15A input from Solar and upto a 90A draw from appliances. Do the wiring between my batteries and bus bars need to be able to handle a combined 105A or just 90A from the draw?
The cable just needs to be large enough to handle the load that is directly connected to it.
It’s only cables that join batteries that would need to manage all the connected loads. Hope that helps.
Hi Greg, I’m just trying to find out what size cables I need and have a question. I’m confused on the type of cables. Everyone seems to use the same amp chart as yourself, but isn’t this for standard wall cables? Why doesn’t anyone recommend thin wall automotive cable which seems to have almost double amp carrying capacity and much higher working heat range?
I am a novice so please forgive me if I’m missing something.
True there are cables that are rated for much higher current so in theory you can use a smaller dia but you also need to take into account the voltage drop on a small cable due to resistance. To help you better size your cables use this free cable sizing calculator on the 12v planet website. As long as the result volt drop is below 4% you are ok
https://www.12voltplanet.co.uk/cable-sizing-selection.html
Scroll down the page to find it 👍🏼😊
Curious why these diagrams don’t include separate +/- bus bars. Looking over your diagrams carefully and SO appreciative of your effort and generosity!
You don’t have to install bus bars, if the system is simple enough you can connect directly to your battery. Addition of a bus bar will add extra resistance to the system and cause a small voltage drop.
Have you seen my main camper wiring video too 👍🏼🤩
How to Wire your Camper Van to be Off-Grid

What a brilliant video. Makes sense of a complicated subject in a clear concise way. If you are not a teacher, then you should be. Thank you.
Well kind of but only on YouTube 😃👍🏼
Hi Greg, I am confused regarding the fusing of the PV cables for the solar panels.
I have two 150W solar panels that I am wiring in series as per your solar video. Do I need to calculate 300w/12v = 25A + 20% for my PV cable fuse size?
No look at the details on the sticker on the back of the solar panel to see what the max amp figure is. That will stay the same if wired in series so just add 25% to that. Typically a fuse of 15amps will be good to use. Like this one https://amzn.to/3jlJ5uc
Perfect, thanks a lot! 😊
