Greg, welcome back 🙏 this video is so beneficial! Thank you for the video and the parts list! I liked and commenting before watching! So glad to see you!

[@GregVirgoe]

Bisho Khan I really appreciate your support it means a lot. Thank you

[@bishokhan8926]

Greg Virgoe haha it might seem a lot but it’s the weekend here in the USA still and I’m binge watching more of your videos. Great details on the wet bath, cupboards, and also ur sketchup tutorials are second to none! I will def be referencing your vids when I buy my first van to convert!

[@johncrisp6683]

Thank you. Very good video and information. I have found auto/van information rather under sized vs marine. Thank you for showing the details. I have shared your channel with the Vanagon Group.

[@samhayes3725]

Thanks for such amazing detailed advice! Your videos are a huge help to so many people and I thank you for that. I have a specific question about fuse sizing and wondered if you would be so kind as to help? I am using a 12v to 5v converter to power some USB strip lights in the van. When sizing the fuse for this, should I consider the spec / requirements of the converter alone, or the converter and USB lights combined. In essence I am using a converter 12v DC to 5v (two female USB ports) to power an appliance 'permanently'. I really appreciate your time and assistance! Many thanks

[@livingthedream8327]

Greg does it exactly as it says on the tin. Down to basics. No music, no 2 min intro. Straight in to it. Top man.

Still confused as to what I can achieve, just starting to try get my head around the electrics, can the led spotlights be the 12v touch ones, how does a fridge work off grid, can I have a split relay and can I fit sockets from the invertor? Greg help! Please xxxxx

[@Mr-x-683]

Found your video 4 years later 😅. Very nice video and very nice explained 😊. One thing to mention is that the cable situation can also be applied to boats. Hence the reason I clicked the video. Thanks for your video !

[@alitheiaziton5188]

Being a spark this is a breath of fresh air listening to someone who is willing to do the leg work to do it as it should be done. Clear, concise tutorials helping folks avoid disapointment. Awesome channel!

That’s great to hear from someone in the trade. Thank you 🙏🏼

[@passenger3]

Really is a cut ✂️ above the rest and greg is super easy to listen to 👌

[@s1dew1nd3r4]

correct me if im wrong mate but wouldnt a 1mm cable size have been more than ok also??? a 1mm cable going off his table allows upto 12amps for 3-4 cableS!

[@mindseyeimaging]

no stupid music or poncing around, down to earth common sense, id came up against a mental block about building my van, listened to Greg for a couple of hrs an he's gave me confidence to crack on, cheers mate, on with the build

[@GregVirgoe]

That’s really great to hear, thank you Chris and best wishes with the rest of your build.

[@jessmatthewson7775]

Me too Chris...let's do this thing... Greg, your presentations are so much clearer than the college version ...🤔 would a t-shirt that said 'crack on with it by Virgoe' be a good seller...maybe with a van silhouette in the background...ill take an extra large in dk navy blue or black lol

[@mjremy2605]

Your videos are a treasure! Thank you for the safety tips, invaluable information that saves lives. Thank you, Maestro!

[@craigverwey983]

You saved my rear end. This was the best video on youtube about the subject. Believe me i have watched them all 😂 cheers 👍🏼

[@jeffdocherty]

Greg not only are your videos well thought through and carefully planned, your presentation is so calm and patient which is key to helping understand a subject area listeners are trying to grapple with. You're so helpful. Thank you

[@tillieedmunds7086]

I’ve started to build my dream home on wheels. I’ve literally used a drill, saw and the like for the first time last week. I’m overwhelmed and terrified I’ve bitten off more than I can chew! Then I found your channel. Thank you so very much for all your work. You are literally saving my life. I almost used cables that are too small AND not flexible. I’ve also learned from you that just cuz someone sounds good when they speak does not mean they really did any research. Thank you from the bottom of my heart.

[@GregVirgoe]

How is it going with you build are you all done now? 😃

[@gcolabufo]

Is it possible to have a favourite person? Also, I'd like to meet the 57 dislikes on this... how? Greg, you're by far the best guy for the job! Fantastic. I was first drawn in by your insulation vid and it just keeps getting better. Thank you SO much!

[@nomadicwanderer1299]

I have come back and re watched this video each time I come back to do more work on my van; I have ALWAYS hated electrics! Someone starts explaining something and my brain goes into overload EVERY single time :-( !!! Greg makes it so very simple, visual too (I’m a visual learner, and slow uptake) Greg takes complicated stuff at a steady pace, showing different ways. Also met this guy once in person he is simply and A1 person; too bloke, too videos, we are incredibly lucky to have you Greg! (I follow Eamon and Bec too, not many others anymore, & believe Greg’s videos have made it all the way over to them too! Eamon uses them a lot too!) all our best to you Greg

[@GregVirgoe]

That’s really nice of you to say so. I am really pleased that they have helped you. If you ever get stuck you can always ask me a question and I’ll do my best to answer it. Many thanks and best wishes. 😊

[@martynharveythepoet5114]

This is absolutely brilliant. As someone who barely scraped an A-Level Physics 40 years ago and is now wishing I'd listened now closely (as I'm wiring my home solar/van system), I have to say that this is so well presented and explained that this should be a model for all such videos on KZbin! Greg explains this all so clearly and at such a great (medium) pace that it neither loses you (by going too fast) nor makes you fall asleep (too slow)! Also, no unnecessary background music! Great job greg - Thanks! -)

[@gerharvey7758]

Greg, I can’t thank you enough for the content you create. I’m three weeks into a Ford transit conversion and have been consistently reassured and guided by the videos you share. You’ve helped me decide when I can do something myself, when to ask for help and when to consult a professional! Thank you so much and please keep creating and teaching :)

[@GregVirgoe]

That really great to hear. Thank you for taking the time to comment. Good luck with the rest of your build. 👍🏼😊

[@adamnewman-4245]

The ability of wiring veing able to handle more current when in the ambient air is the reason why I like my wireson the ceiling. Also, in the event of a fire, the fire can be put out more quickly,

[@GregVirgoe]

If the cables are sized large enough there is no risk of fire.

[@rumo558]

My dad was an electrical engineer, I wish I had paid more attention to what he told me. I came across this video along with your water system, brilliant. I've just decided to upgrade my 43 year old Tabbert caravan, instead of spending a shed load of money buying a newer one that's had a hard life. The parts all start arriving tomorrow, so your video has been gratefully received, thanks. I'm off to watch another of your vids.

[@GregVirgoe]

I’m really pleased you liked it. I can recommend my recent 12v wiring video as it will help to explain how it all comes together. 12v Electrics for Off-Grid Campervan - Fiat Ducato Budget Build Ep12 kzbin.info/www/bejne/rnTaaJh3h69-hck

[@MonkeySpitone]

Greg this is just amazing! I was really perplexed by all this until I found this video and the resources you've made!. Thank you!

[@garryharvey9029]

Been watching all of your tutorials and European trips over the last few months and can honestly say you've been such an inspiration. The detailed van built tutorials have been and will be invaluable over the next few months. Thanks again Greg and keep up the good work.

[@mannab2975]

To remember the Watts circle, start from down right, then left, then up. "A Volks Wagen". I love this easy way to "Take away what you need....then see how to calculate!" Excellent!!

[@GregVirgoe]

Oh yeah, that’s a great way of remembering it. Nice one 👍🏼😃

[@dvaemay2420]

Very good info, as an ex-electrician I thought I'd watch this for van-installation specific info. The first 5 minutes gave lots of good tips (conduit, never thought of that). The only thing I would highlight is that the solid core (which you're not going to use anyway) was old-standard colours - black and red not brown blue. Current carrying capacity vital info' for safe installation. Thank you for the reinforcement of information that I might have forgotten! On to the solar installation vid' now... too modern for my knowledge!

[@kadachiman7234]

I have been binge watching your videos as you present the topic content very well, great job. Initially I searched for 'how to insulate a van correctly' as there seem to be many view points, so it was great to see your view supported by factual and mathematical data. I am an electrician in Australia therefore different regulations than you have there, so you are 100% correct in pointing out that anyone watching needs to refer to their local regulations, as Australia has many differences (mostly minor) than what you have presented. One thing to keep in mind when you referred to the wiring table, is that the tendency in van builds to to bundle all of the wires very closely and tightly together, therefore this has an effect on 'electrical heating ' of the cables by the current flowing in adjacent cables.......therefore it is mostly wise to go bigger if in doubt, and/or to try to segregate your higher current draw cable runs.

[@kirilstankov]

As I am starting building my own van now, I have came across many videos here. Most of them sound and look like a dance party. Greg is practical and explains everything in details, diagrams, scientific explanation, formulas, etc. Well, some rock'n'roll from time to time won't be wrong :). Greg - the van convertion professor! Thank you.

[@5675421]

What a fantastic video! Simple, clear and incredibly useful. Beginning with electric work is daunting, and the level of confidence this gives is enough to facilitate the beginning of that journey. Thank you

[@Stephan5150]

I've watched too many of these videos and nobody was able to put it together is such a basic easy to follow format. I now know that for sure that I have a firm grasp on the topic, thanks for sharing!

[@GregVirgoe]

I’m glad it has helped you. I have a few more wiring videos that you may also like 👍🏼😃

Just bought a Fiat Ducato L2H2 and about to start doing my first ever build. Been wandering around all over the place looking for information, tips and brains that can take the place of mine in things like Electrickery which totally eludes my grey cells. Running around in circles it started to feel like...and then I found you Greg. Yours is the clearest and most informative video I have found. Thank you SO much! I shall recommend you.

Rachid Ben thank you very much for watching the videos. I’m pleased you like them and hope they will be useful for you own build. Good luck 😉👍🏼😃

[@mamastarandlittlerainbow3771]

Great info. The electrical is the only part of the build that intimidates me. Having a dedicated playlist for this is a great idea. Really interesting info about the difference in the current being within an insulated wall vs on the outside of the wall. My plan is to put the wiring outside of the wall so having this info is super helpful. Thanks so much!

[@GregVirgoe]

Yes I thought it was very relevant as lot of people, me included have buried cables in walls and because they are not in free air and potentially can be hotter you are not allowed to run as much current through them. Makes a big difference to the figures.

[@larrierobinson8525]

Hi Greg, You are so giving, genuine and well researched. Thank you for the time and detail in the various videos you produce so professionally, they are of great help. I am in Aussie and are doing my first van, a Toyota Hiace Super Long Wheelbase.

[@GregVirgoe]

David Lisken this video in conjunction with my latest wiring schematics and full system video should give you a great basis to go with. Most appliances need a positive and negative. A fuse in the positive. The right size cable and maybe a switch for control. When you break it down it becomes very logical and easier to understand. Good luck with your build.

[@sunnycampers4249]

Great vid Greg, thank you. With any wiring installation, it’s sometimes hard to understand how much energy builds up within the cable when appliances are switched on. Your clip showing a wires heating and subsequently melt/combust shows what could potentially happen behind the insulation in a van. Therefore your visual demonstration and clear cabling sizing chart will enable us all to sleep safely. Cheers!

[@GregVirgoe]

Obviously the video clip was very dramatic but hopefully it emphasises the importance of having the right size cables in your van. Like you say most are buried where you can’t see them so you don’t know until it’s too late. Electrical faults cause many fires in houses and campers. Thanks for all your support it’s really appreciated. 👍🏼

[@arthurrobertson658]

Hi Greg, good information for all the busy lockdowners! Regarding the 230v side of things, remember BS7671 states that 230v circuits need overload protection that breaks all live conductors in a caravan or mobile home. I'm sure you know that on 230v the neutral is also a live conductor so that means double-pole mcb's.. This means that your 230v distribution boards can get quite big as we usually have battery charge circuits, water heating and sometimes electric space heating for when hooked up. And watch out for rcbo's as most are still single pole break operation, not double pole as required. Keep up the good work

[@michealplater9007]

In austraila the outlet has to also be double pole

[@jwern151]

God bless this man! Thanks so much for the incredibly informative video, cheers

[@melissafields6628]

This is amazing. I have watched so many videos to learn the electrical for my bus build & you have been by far the best teacher I have seen. I wish there was an American version.

[@GregVirgoe]

You can simply google a cable size conversion chart to change to AWG sizes 🤩

[@dub_rider]

briliant video! i've recently got into playing with 12v and solar in my shed. I've been looking everywhere for more info and had lots of questions that needed answering. after hours of youtubing i finally came across this one and not only has it answered everything and more, but it was clear for muggles to learn from. I now feel empowered with the knowledge i need to move on with my project. thanks so much Greg!

[@brucefay5126]

Excellent video, Greg. Here in the “States” I tend to use a split conduit. Similar to the conduit you showed but with a slit opening the full length. I find it quite a bit easier to install (after the fact) than the coiled loom you showed, although I sometimes use that too.

[@GregVirgoe]

Bruce Fay yes that is another good way of doing it. Of course you can take a utility knife to the normal conduit if desperate. 👍🏼😊

[@JoshWedgwood]

Thanks Greg, great video as usual. You might have thought this too complicated but one thing that might be useful to let people know about is the voltage drop across a long wire e.g. front to back of van. This voltage drop needs be be kept below ~3% and will also affect wire area choice. I have my van battery in the back, so definitely something I have had to consider with my battery to battery charger. There are some useful calculators out there to point people at perhaps (e.g. on 12v Planet). Thanks!!! Been using your videos loads in my conversion!

[@GregVirgoe]

Not complicated but this video was already getting very long and people start to switch off and don't take in what you are gone through if you bombard them with too much at once. I was planning to cover that in a future video as it also applies to fridges etc

[@militantvideo]

very informative! thank you for this. I've watched longer videos that taught me much less. I had no idea amp ratings dropped according to mounting conditions.

[@GregVirgoe]

Yes it’s all to do with the surrounding temperature of the cable and it’s ability to get rid of any heat build up when running. 👍🏼😃

[@johnmandy]

@Steve Kirk So you’re not going to use the comment you’ve left on all of my videos? I thought you love nothing better than to pint out if someone lacks electrical qualifications - so really you’re a dick who just trolls me to all my viewers telling them to ignore everything I say. What a joke you are.

[@Knolraab]

I really appreciate the fact that you take the time to explain this stuff. In particular the safety side, like not using solid core wire. This is overlooked very often. I wanted to add that when using multicore wires it is important to use the right connectors. Make sure they are rated for the correct current. But also that the stripped end of the wire is properly clamped in the connector. There should be no exposed copper (cores), as over time some of the cores can break and could fall out and cause a short. Use heat-shrink and or heat-shrink to prevent any cores from falling out. Especially in areas with sensors. At 11:20 you are right that this is not the proper way to wire it, however the explanation is not correct. Assuming all 8 lights are the same each light would have the same voltage potential across it. The first light would have 12V (with respect to ground) at the positive lead. The negative lead would be 10.5V (with respect to ground). So the voltage potential across the light would be 1.5V. This is the same for all the lights. Since the lights are wired in series, the current is also equal for each light. This means all the lights will be equal brightness. In the case of a regular light bulb all lights would be very dim, but the same brightness. When using LEDs (like in the example picture) the lights would probably not turn on at all, since leds are diodes that require a minimum voltage to operate.

Hello Greg . Darren here mate. Living down under as my english friends over there say.. lol this is the first time I have seen your site. 👍 I have never had the most important part of the wiring diagram. ( correct fuses ) With such easy instructions to follow. Mate THANK YOU so much Greg. Have a great life stay happy. Kind regards Darren Mortimer. Qld. Australia.

[@andys844]

I'm not sure if you've covered this elsewhere, but another thing to factor into the wire size choice is voltage drop. Especially on 12v systems you can drop a significant percentage of volts over modest cable runs and loads.

[@charlieboylinton]

Thanks so much Greg. For someone like me with hardly any knowledge on this subject your videos are very informative in as simple a way as possible - good job :)

[@dogfatheryonker9945]

Wow, your info AND Schematics on 12v installation were awesome. Being from USA, your accent was mesmerizing yet it was easy to follow your instructions. I’ve been looking for this type of video in order to add accessories to my golf cart. Now it seems like a piece of cake thanks to you. 👍👍

[@zacjy]

Nicely done Greg, I wonder how many vans have you to credit so far! Just one small point to correct, if you put several (equal) lamps in series they'll divide the potential equally. As a result the first won't be any brighter than the rest - they'll all be equally dim! 12v ÷ 4 lamps 3v drop per lamp, i.e.1/4 of the12v required for full brightness.

Hi Greg I don't know if I have already said this but your videos have helped me while I renovated a caravan 2 years ago. So If I haven't thank you so much for your simple straightforward advice & education on all of this stuff

[@GregVirgoe]

It’s always nice to read a comment like yours. It makes my day to know that it has helped you and I thank you for watching and taking the time to leave me such nice feedback. Best wishes 👍🏼😃

[@alanmesfin]

This is amazing!! Exactly what I needed, thank you, Greg! Quick question: when wiring the lights in parallel, I'm not sure how to make the connections between the 2-core cable and the light wires. The way I understand it is that you run the 2-core cable all along the lights, and wire in each light by wrapping each of the positive and negative light wires around the corresponding 2-core cable wires. I'm just not sure what this will look like. Could you clarify please? Thank you again and I cannot wait to watch the rest of your recent master classes!

[@TheAffrojutty]

Hi Alan, your question here is my question too. Not quite sure how it all looks/works with 2 core cable. Did you get the answer you were looking for?

[@alanmesfin]

@@TheAffrojutty I didn't, but I have found something called "T Tap Wire Connectors" which seem to do this for you.

[@tdivyak]

This is super clear and to the point. For us non-electricians, this makes a DYI job seem achievable. I especially appreciate the information on wire sizing and how to size based on wall or conduit mounting.

[@NomaddUK]

And he finishes with "...in this current situation.". I see what you did there. Well done. As usual, Greg, very useful and especially the sizing chart. I do have a question which I have tried to get answered previously but still don't have an answer. I have a Renault Trafic LWB. The roof space is not huge but I can get upto two solar panels on it. What would you recommend, a single large panel or two smaller panels? What are the benefits of each scenario? I can guess at one which is that multiple panels increases the volts if in parallel (If I got that right way round) which is better for the controller. But this also means that if a panel is shaded it has issues too. Thanks.

[@GregVirgoe]

Nomadd UK I think the biggest consideration is that it fit the space you have available. Two panels will give you a bit of redundancy if you have a fault but that is rare. Multiple panels are best wires in series to make most of mppt max power point in low light conditions. 1x300w panel is the same duty as 2x150w panels 😊

[@RickSanchez-ye9bi]

Hi Greg, thanks for the video. I had a look through your playlist, do you have anything on 240v hook up for sockets? I'm renovating an old caravan and will be installing them, you seem like the guy to get advice from....

[@scooterjes]

One minor mistake on the USB sockets that 3.1 amps @ 5v not 12 but still you have plenty of margin for error since more volts equals less amps.

[@GregVirgoe]

Thank you James, I could find if it related to input or output so aired on the safe side. Like you say my fuse and cable are oversized so that’s not bad thing. Method is still the same thankfully 😅

[@mustin2450]

@@GregVirgoe Hey Greg first of all thank you for sharing all your knowledge on so many different topics with us. There are so many things that needs to be considered regarding a van conversion that it's virtually impossible not overseeing something but with your series of detailed videos I think many people have found a starting point and help. I found your explanations on the insulation very interesting. Beside that the safety thing depends on one's point of view. The question that needs to be answered is what the fuse is meant for. In your example the fuse is chosen correct to save the wiring it fail its purpose however if it comes to saving any device. For example let's assume you have a malicious phone charger on one USB port. This charger will drain 15 or 20 amps and light up before the fuse will break the circuit. Daisy chaining these sort of things makes the wiring easy but you should keep an eye on build in fuses in each component.

[@kieranragan6641]

Not exactly true. Amps = Watts / Volts, therefore regardless whether you supply 12V or 5V to the USB socket, the only thing that will change is amount of Watts the appliance will use. These USB sockets contain a buck converter to lower the voltage down to 5V. The Amps used by the appliance will still stay the same regardless of what Voltage you supply it, the only thing that will change is how many watts of power the buck converter within the appliance uses to convert the voltage, which is most likely why the product is rated in amps and not watts, because it can be fed a variable voltage. He did exactly the right thing here when deciding on cable thickness and fuse rating 👍

[@veseloiu]

This is, most probably the most useful pack of information on the electrics of a camper van excellently presented. I cannot thank you enough. There is however, just one aspect that contains an error: At the minute 11:31, If identical lights are connected in series, as theyare identical and they all have the same resistance, and as the same current (intensity) goes through all of them, (since they are in series) so the voltage drop across each light is exactly the same, and the power dropped on each lamp is the same so the brightness is the same so they will all be quite dim but just as dim as each other. But the conclusion is still 100% right: the lights and all the 12Vcomsumers should be wired in PARALLEL. I hope this helps. with best regards
