thank you for not aggrandizing yourself with music, intros, etc. Nice work. Very helpful
THANK YOU! someone who explains it all perfectly and clearly. No bs rambling about nonsense or stupid music. Thank you so much, seriously..
No problem, glad it helped 👍👍👍
What size battery would I require to run, heating, lights, tv and fridge?
most simple video explanation ive found on this subject so far filled me with confidence on tackling this side of my van build Thumb up and subbed!
Top man, yours is the only video to show the use of a breaker. Simple but so effective. I’m just about to start my conversion and I’ve ordered the breaker. 🙌
Glad it helped mate 👍👍👍
The video I’ve been looking for all this time. Thanks mate. Clear and straight forward 👌👍
Glad it helped you 👍👍👍
Brilliant sentiment to think to pass on the knowledge - much respect !
can't tell you how many videos I've seen and still baffled until I came across yours. exactly what I needed.great vid and great explanation going to order the bits now . cheers mate
Glad it helped mate 👍 👍
simple, and easy to follow, cheers mate! much appreciated
Cheers mate , glad it helped 👍👍👍
Good simple video but a mention for people learning is the importance of the right wire size for the amps going through it, and the fact that the fuse protects the wire not the items on the end of the wire.
Perfect. Just what I have been looking for. Thanks
Thanks for the video. After reading up on this this video is the final piece to the puzzle of me figuring it out.
Glad it helped 👍👍
Very informative, some videos blind you with science... yours is easy to follow... Great job
Steve
Thanks mate, glad it helped 👍 👍👍👍
Simple and easy, nice video Tommy.
LEGEND!! Quality video mate. Genuinely simplified it all! ❤ Thank you.
Thanks mate , glad it helped 👍👍👍
@@LT_TOMMY_ Honestly buddy. Really has.
Cheers pal, just what I needed to watch to get me started. 👍🏻👍🏻
Very helpful and easy to follow video. Thank you Tommy..... 👏👏👏👏🚐☘
Exceptionally well explained, mate. Thanks so much and keep up the great work. (From Melbourne, Australia)
Thanks mate, glad it helped 👍
love this video, easily explained and connected
Thanks , glad it helped 👍
Great video, right to the point and thoroughly explained 👏👍
Glad it helped mate 👍
Great video mate. Something I’ve always thought would be difficult but very good info there thanks 👍👍
Thanks mate , glad it helps 👍
Thank you, well explained
Thanks for sharing with us this video. That's a great souvenirs from my best time to Lockheed M .Georgia on c130 Hercules 🙏👌
2 mins in and can already tell this is going to be a good video - I’m doing a caravan project on my channel! :)
I love your easy to follow. I watched your first one.
Your van looking great. I'm off to see the rest of your videos. Thanks.
Glad it helped and thank you 👍👍👍
@@LT_TOMMY_ me again 😊, do you have one made on fitting a consumer box, Iv made a start cutting and fitting 240 socket. No worries if not. Have a great weekend.
Like it starting journey and this defo helped me
Looks OK to me. A little bit unconventional but I won't quibble. It is certainly safe and functional. When I was working with aircraft they said something to me which seemed odd at first but makes perfect sense. "Fuses are not there to protect the devices, they are there to protect the wiring." Cheers.
I usually have about 10 things hanging off my battery thanks for the video 👍
Glad it helped mate 👍🏼
It’s a great job 👍
Thanks mate 👍👍👍
be very careful with that breaker and the diesel heater. if you fx leave the van and the heater hasn't gone through its cool down sequence , and you trip the breaker because you want to shut down all power for the night, the heater will fry the main board because of over heating. Easy mistake to make! I wonder if it wouldn't be better to wire the heater directly to the battery for continous power. Also, I see alot of those screens lcds go out. people recommend putting a switch on it when not in use to conserve the lcd. (same applys though with the shut down sequence, not sure if turning the lcd screen off cuts power to the whole heater, needs to be looked up!) good job on the videos!
You know what, that's one thing that i didn't think of ...
May put it directly on the battery instead, cheers for the advice mate 👍
@@LT_TOMMY_ if you wired the heater directly to the battery (giving continuous power ) would you then simply turn on and off as required? and now further down the line after this was aired are you indeed doing this Im about to start a build and Im looking into electrics and im being very careful to observe all this stuff as I dont want problems
get control with red remote lot better atkins is correct
Good info.
Nice and easy to follow mucho grais amigo
Glad it helped 👍👍👍
Helpful video. Thanks man
Glad it helped 👍👍👍
Great help thanks
Spot on 👌🏻
Buen vídeo 👌 gracias.
,that looks good
Thank you buddy
Much appreciated
Bang on!👍🏾
Hi. In the states we say, hot or feed for the positive wire. And If it’s a wire heading to switch out to the light 💡, we say switch leg. Overall good video
Brilliant 👍👍
Cheers pal 👍
Helpfull, thanks!
Glad it helped 👍
Good job.im on it
Thank you 🌼
You're welcome 👍
Very well explained. Would normally use different grounding points around the van for each accessory. Was interesting to see how you ran the earth from the accessories to the switch and doubled up the earths for both switch and accessories and put them both straight into the negative side of the fuse box.
yeah, I am wondering about that. Can you Earth the installed campervan electric system to the van chassis. That way only a positive feed need be ran to anaccessory, with a small lengthe lead to the vehicle body acting as the negative for it?
Also those cheap Chinese breakers (yours might be the genuine one that is 3 times the price) have a poor quality record so good to test them first before relying on them 👍🏼
This is all strange alchemy! I can't even wire a plug without double guessing myself lol. Thanks for this Tommy
I'd always help out of you needed mate 👍👍👍
Hi Tommy
Great video,very easy to follow.I was going to fit 2 110AH batteries to my van.Would I need to upgrade the relay to accommodate the batteries.all new to me so any advice would be welcome thankyou
Hi good video very helpful what size wire did you use for the led lights ? Thanks
Thanks for the video a great help
Glad it helped 👍
Can I ask where you bought the bits from
All from ebay mate , a few bits are linked in the description of the video 👍
Thank you sorry didn't notice the description details thanks for you reply and the video again really is a help thank you
👍👍👍
Thanks for the video. I've got the same setup but I've added 6mm cables from the fuse box to a 12v plug to power my fridge. When I turn everything on, the fridge screen says low voltage and won't cool down. Any suggestions? Thanks 👍
Mycompact fuse block arrives by mail tomorrow
I have a 5 gang inline switch panel. Can this be used as the switches for my lights, water pump ect and just wire this into the same fuse box used in this video
Nice video! Can you please show how to connect the wires to your inline circuit breaker? You sped up the connection and couldn’t see how you wired them.
Great video. Silly question: does the 10mm cable you're using have 2 cords in it (pos and neg) or is it just 1?
Thanks👍 , No , the live is a single core and the Earth is a single core, never a silly question if you dont know 👍👍👍
You can get cable with two cores in 10 gauge. I use it for remote fuse blocks in my installs. They won't be inside of a sheath, they will just be stuck together and very easily separated if you need them to be.
I have an old dodge campervan. Can someone explain the black wires vs the white wires. Which one is positive and which is negative. Thanks
Thanks so helpful! Where did you buy the multiple metal terminals on your +ve and - ve battery please?
Thanks , glad it helped , they are terminal crimps , you can get them in most diy stores , or you can get good sets on ebay 👍
Have you got the power coming in from your car battery to the fuse then to the charger/relay and then through another fuse then to positive on to ur deep cycle battery?
What size battery would I need to run a fridge, heater, lights and tv?
What size wire for lights etc and how do you know what fuse to put in thanks in advance
The fuse for the LED's looks like a 5 Amp, because LED's draw so little current I'm sure the fuse rating should be 1 Amp.
Great video but should the earth wire not be a lot thicker than that?
Nice. But how would I know what fuse to put in for each item?
Hi Tommy. How do I decide whether to use a 50 or 30 amp circuit breaker?
Hello Tommy,
Thanks for this video its super helpful for someone like me! Can I ask what is the name of the metal attachments you have on your battery to connect the wires - I dont have these and i need to buy some!
Thank youu
Glad it helped 🙂
I think you mean crimps .
Is the battery your running it from the main battery for the van? Cheers
Just found this video (good old algorythms...LOL)...I always get confused when wire sizes are mentioned. So your 10mm wire was 10mm2 wire [ 7 awg ]???? I use 6 awg in my layouts...
What size is ur fuse in the diesel heater and wt size cable. Thanks
Nice vid. Can you explain the reason for 2 fuses from the split charger. Surely one large fuse from the leisure battery to split charger is enough?
So the fuse protects the wiring not the charger. He is protecting the wiring from the van battery to the split charger.
Really good concise video here bud. Quick question: Once all the fuse box is filled, presumably you would wire in a n additional one via the battery again with a new separate breaker?
Thanks mate 👍
You can get bigger fuse boards that take more , may be easier to get a bigger one rather then run 2 👍👍👍
@@LT_TOMMY_ Thanks for the reply Tommy
I got a 2012 crafter lwb, does yours have a smart alternator? dont know if i need a split charge or a ctek battery charger?
mine doesnt mate ,i was told if your battery has a small black box usually on the negative side cable then that could possibly be a smart sender , if its just cables only then its not smart.
im not a mechanic, this is just what i have been told , mine works fine .cheers
It's the 3 wires on the switch that confuses me negative and live I get were dies that 3rd wire end up
Great video,got same set up in my van I'm planning to put in a couple of usb sockets any ideas of wire size amps etc....cheers mark
Hello mate , cheers 👍
Ive used 1mm for my lights and usb plugs , i wont be using anything thats high wattage so it should be more then enough 👍👍👍
@@LT_TOMMY_ cheers mate, wish me luck
I'm guessing you could use that breaker as an isolator switch as well?
Exactly 👍
Hi how is your electrics going please can you tell me how much your electric setup was cheers 🍻👍
How do you wire those inline breakers? Do you need a ferrule or something, or do you just wire straight into them?
Hello mate , you unscrew each end, put the cable in, screw it down and tighten the ends 👍
Can you not use the body of the van as the negative for all the accessories coming off the leisure battery?
And then ground the leisure battery?
Asking because I don't know, not a surgestion 🤔
Hello mate, earthing your appliances to a decent clean earth point on the van should be fine .
Other then saving on a bit of cable it would be much neater using a fuse box for both 👍
Nice video, does the wire to each accessory need to be rated for the size fuse you are using?
No, the fuse is to protect the wire, not the accessories.
Eg: 12v fridge draws max 5a, a 15 or 20a wire would suffice, using a 10a inline blade fuse (or the blade box used here)
Also position the fuse as close as practical to the 12v supply
Hi Tommy. Why the 50amp breaker? Is it to protect the system from over charging?
Not from overcharge but just extra precaution 👍🏼
Do I need an inverter if I’m using hair clippers in the van as a mobile shop?
Yes 👍
This is for 12v power only
I don't want to be picky, but have you used the right size wire for the amps that will be going down it? I would hate to hear it went on fire?
10mm cable with a 50a breaker plus run into another fuseboard.
It's plenty enough 👍🏼
But definitely nothing wrong with being cautious 👍🏼
@@LT_TOMMY_ no worries Bud, all good then👍
Been searching for a video on this, really good simple instruction👍 one question - without that breaker would you need to disconnect the battery to work on the fuse box ?
Thanks mate 👍👍👍
Better to be safe then sorry.
Either disconnect the live from the leisure battery or the live from the fuse board for the sake of 2 mins👍👍👍
Van Life Tommy ideal cheers mate
No worries, if i can help in any way just gis a shout 👍👍👍
Van Life Tommy will do, about you attempt to wire in lights tomorrow 😬
Your be fine pal 👍
Hi there, does he mean 10mm squared (8awg) cable or just 10mm width including the sheath?
Thanks to anyone who can help
Is the lesuire battery ground to the van body ?
Yes mate, clean metal 👍🏼
hi can some1 tell me if ya need to use an inverter when doing the wiring this way thank
You can wire the inverter directly to the battery negative and positive with a fuse on the positive and you ground it to the chassis and you are ready to go to use your 240 power.
Nice video Tommy real helpful to see. How does the cable go in to that breaker is it a crimped fork connection you need or just strip the wire and screw it in? I'm ordering all my bits now!
Thanks mate , glad it helped , i crimped all mine for a decent fit 👍
@@LT_TOMMY_ Thanks Tommy!
Sorry mate , i read this wrong , the cable going in to the 50 amp breaker just pushes in and screws down , the cable going into the fuse box is crimped 👍👍👍👍
@@LT_TOMMY_ Cool thanks for the update. I got one more question if you don't mind, I seen loads of people using a 12v switch after the circuit breaker, do you know is there a reason for that seeing as the circuit breaker also works as a switch? Seems a bit pointless otherwise
12v switch as in a normal light switch etc?
The breaker is just extra protection for the wires etc.
Tommy how do work out what size breakers i need going from batt to fuses
The cable size always need to be rated higher then the breaker or fuse size .
I'm using a 10mm cable which will give up to 70 amps protection which means a 50amp breaker will just be lower then the cable rating and should work fine 👍
@@LT_TOMMY_ I know nothing about electrics mate. If i use a 16mm cable what breaker should i use? Thanks
Will 1 battery be enough as most I see have 2.. like to only have 1 if possible
Hello mate , 1 battery has always been fine with me , i usually do small festival trips or holidays not much more then 5 days.
I can comfortably run my diesel heater, lights, tv and phones charging for 4 nights , i haven't tried any longer to be honest.
I would prefer 2 as back up and possibly will do in my new build👍
You made that look so easy. The link is dead and I am worried about buying a circuit breaker thats not safe, could you provide an up to date link for one that you would recommend please? I am going to use it in my camper van.. Thanks so much for the tutorial.. :)
Hi 👋
The link is now updated, here it is , this is what I would personally use ,select 50 amp👍

What is your battery?
Whats the fuse wattage my friend? Sorry new at this 😊
What is the breaker between positive and negative on the battery?
Hello mate , the breaker on the live between the battery and fuse box is a 50 amp breaker.
Is that the one you mean ? 👍
@@LT_TOMMY_ yes i understand the 50amp breaker on live wire for fuse box i didn't quite understand what is connected and Fused from plus side to negative side on the battery itself? Cheers thanks Tommy
I hope I am wrong, but are you sure the large red is 10mm, it looks like 6mm to me, the reason I ask is that usually yellow crimps are 6mm (blue is 2.5mm and red is 1.5mm approx.) If it is 6mm then the breaker is rated too high, its only just on the mark if it is 10mm as it depends on what type of cable it is and the rated temperature of the insulation. Sos to be a buzz kill.
Hello mate , yes the Red and Black are both 10mm cable 👍
Great, glad to hear it, might be worth checking the crimp terminal size.
Will do , cheers pal 👍
What happens when the battery dies? Do you buy a new one or recharge it?
Hello mate , the leisure battery is on a split charge relay meaning when i drive the van it charges it up👍
Tommy where did you buy the 10mm cable from ?...steve

Hi Tommy nice vid thanks for sharing easy to understand just one question if that's okay
From the leisure battery do I need to earth it to the van then to the fuse box or straight to the fuse box I have the same one as you thanks in advance
Subbed and liked chees
Thanks mate , glad it helped 👍
Mine's got an earth straight from the battery to the fuse board mate 👍👍👍👍
Thanks Tommy for the fast reply will be watching all your vids tonight in work and look forward to more coming good luck take care 👍👍
Thank you mate , much appreciated, are you filming your build? If so I'll sub👍
Sorry mate , just read this back through, my leisure battery is also earthed to the body 👍
I dont understand how youre saying the fuse board is earthed from the battery negative post. Surely the battery negative also needs to be earthed to the chassis. I am at this stage in my electrics having done my electrical hook up and 240 sockets which I earthed to the chassis. I though all house batteries had to be earthed to the chassis @@LT_TOMMY_
what size of wiring
1.5mm 👍
nice simple easy to follow instructions. Is the leisure battery or fusebox earthed to the bodywork? do any of them have to be? I did see you mentioned the splitcharge was earthed to the chassis via a bolt.
cheers mate, enjoying your videos
Cheers mate , hope they help a little bit 👍
So positive from battery to fuse holder and Negative from battery to Negative on fuse holder .
The only thing i earthed to the bodywork was the split charge 👍👍👍
Did you not earth the battery to the bodywork@@LT_TOMMY_
I hope you have another fuse at the main battery otherwise all that 10mm cable going to your relay is unprotected
2x fuses with the relay kit plus a 50a breaker between leisure battery and fuse box .
@@LT_TOMMY_ yeah but the fuse is at the wrong end of the cable from van battery. it should be right next to van battery or you have a long cable run from the bonnet to the fuse I can see that is unprotected.
@@keithstead520 No mate , the first fuse starts under the bonnet about 5 inches away from the starter battery.
