DIFFERENT TYPES OF DC FUSES (for a DIY Camper Electrical system)

[@wademchenry1560]

A critical and complex subject, this is why I recommend this channel to everyone.

[@EXPLORISTlife]

Awesome! Glad it helped. Thanks for watching!

Thanks for another great video, making things alot less con-fuse-ing! (Sorry, I'll show myself out😂)

[@benhoffman7672]

Most AGC-type fuses are rated for 32 volts for DC current AND 250 volts for AC current (50/60Hz). It is easier for a fuse to break an arc of AC current, once the fuse element melts, as the current passes through 0 amperes 100 to 120 times a second. Thank you for producing this video, as fuse AIC ratings are rarely mentioned, and ignoring them can greatly increase the chance of a fire if there is a low impedance short.

[@orvsr4me2]

Outstanding video, as usual. Incredible restraint to accurately call them A N L fuses. I couldn't do it 😂

[@daniellel256]

Thanks! Your diagram was so helpful last fall when we did our battery/solar upgrade. Now we’re enjoying the fruits of our labor. We will be changing the battery bank 400amp ANL to a T-fuse when more become available. One type of fuse that was not mentioned, and this may date me, was glass type t/tl had in my first home. Lol, old school. Thank for all the time and dedication both you and Steph put into your builds and videos. Thanks again

[@EXPLORISTlife]

Awesome! Glad it's been helpful. Thanks for tuning in, Danielle! 😁👍

[@outbackeddie]

Great video. I bought several class T fuses about 10 years ago when I set up my first inverter and I still have a few extras from that project. I was debating on whether to use one of my extra Class T fuses or an ANL fuse with my newest inverter and you have answered that question for me. Thanks for doing this excellent video.

[@campfirecure]

I finally get how to choose between all the fuse options. Thanks!

[@BrianKStewart]

Nate, you took the conFUSING out of fuses. Thank you

Very informative video because I had no idea about the levels of fuses available and the purpose of each

[@angledcanoe]

When would it be appropriate to use a DC breaker in place of a fuse?

Good Morning. Thank you Great info. Jack

[@leonardocaestrello2686]

I recently found out about this channel, really great content! Regarding fuses, I got a question as Im not 100% sure what I should go with.. Which fuse type and size should I use between my 365w (Impp: 10.75A ) solar panel and (30A)regulator (if any) and which fuse to use between my batterybank (12v 240ah) and 1000w inverter? Really appreciated if you could give advice on this 🙏

[@tienies1]

Hi Nate, is my understanding correct that a fuse rating, say 70v 250Amp means that the max voltage I can use it for is 70 V and therefore I can use it as a 250 Amp fuse in my 12 V system?

[@marionsutcliffe1119]

What about features like slow blow / time delay? Are there variants to avoid or choose?

[@mrbranchatl]

Another great video, I learn a lot from them. Thx

[@EXPLORISTlife]

Glad you like them! thanks for watching!

[@9111logic]

Thanks for thiis discussion 🙏, very much appreciated however I'm stil in doubt about which T class fuse I should be using inside my custom 48V Lithium battery. I have designed a fuse holder which I have fitted with a Bussmann bs88 180A fuse knowing that this type can be used on borh DC and AC however, the Blue Sea Systems seems to be rated for lower voltage (125 vs 240fro the Bussmann) and I am concirned that they might behave differently. The bussmann is more readily available at a much lower cost but I wouldn't wont to compromise the circuit so I have been trying to obtain a comparison but unfortunately unsuccessfully so far. Perhaps you could discuss this in a future video ?

[@shameelali2549]

Do you guys use amg fuses?

[@GirdHerd]

Nate, An excellent explanation why you are currently listing the ANL fuses instead of Class T fuses in your diagrams. I noticed a limited supply of Class T fuses two years ago when I was building my system using your 400A/3000w diagram. I wanted a spare fuse so I have to buy a fuse holder just to get the 400A Class T fuse that came with it. Are you putting a footnote on the diagram to use a Class T fuse if available?

[@KJC63]

Very educational - thank you :)

[@EXPLORISTlife]

Glad it was helpful!

[@kim15742]

Is the ampere rating a maximum? I.e., is it ok to have a fuse with „too high“ of an ampere rating or is the range tighter?

[@johnsilver228]

I’ve decided on a subi Crosstrek build and I’m implementing a lot of stuff from your current van build when I comes to construction like using the t-channel square tubing to build out the frame and slotting in the plywood. Looking into the battery and where to put it I saw that you guys use to have a Crosstrek, do you think the spare tire compartment would be a good idea? I’m a bit worried if a fire or short since I’m from Arizona

[@RobinRastle]

You totally missed out on the Euro equivalent of a class T - the NF fuse (aka knife blade) fuse with very long tried and tested pedigree (since WW2 from its German origin Siemens). These have 100,000A AIC. OBTW they can also be disconnected on a live load (with a fuse puller handle and wearing protective gear and having had suitable safety instruction). Downside is the difficulty in obtaining a fuse holder (makers keep this essential tightly controlled, to make you buy a system from them - even though its covered by the IEC 60269-2 std). However the far east have been using this design for years and you can buy a basic open ceramic carrier w fuse for $10 thus breaking the cartel and hopefully your fault current Bottom line is that a 12Vdc system is the safest (YOU CANT STRIKE A WELDING ARC AT THAT LOW VOLTAGE- but you can at 24Vdc) Very good summary BTW and you are spot on at the deliberately engineered complexity of fuse systems.

[@EXPLORISTlife]

Thanks! Yeah; I'm sure there are fuses from all over the world that are not attainable that I skipped over. I try not to show things on this channel that are not attainable by the average end consumer.

[@freetaylor72]

Hey nate, I got a grow watt 24v system with 4 24v battle born batteries, I bought 2 more batteries and was wanting to know what I gotta do to drop them into my battery bank. I can't find any info on what needs to be done to add these batteries

[@landonashby2029]

How would you go about calculating the max amp release for your LiFePo4 battery if were to short? Does the built in BMS protect for this also? I only have one 12v 280ah LiFePo4 Battery in my system. So would the mega fuse be adequate in this micro system?

[@ifell3]

Some of those I've never heard of. Just like to add you also have fast blow fuses and slow. 😁

[@EXPLORISTlife]

Awesome! Glad it helped. Thanks for watching!

[@cbdane]

Outstanding! Will the Class T fuse fit into the ANL fuse holder? I'm guessing not so when they are available, the retrofit will involve fuse and fuse holder? Thanks so much for this amazing channel (and website/store)!

[@EXPLORISTlife]

Class T fuses are a different dimension so they won't fit into an ANL Fuse holder, no.

[@timf6916]

Nice. You do a good job.

[@EXPLORISTlife]

Thank you!

[@ItsEverythingElse]

Do you know of any terminal fuse blocks that fit M8 battery studs? All the ones I see are M10.

[@dmcd2023]

Hi Nate, Your videos and documents are invaluable in designing the system for my new travel trailer that will have 600Ah of 12v battery, 1200 watts of solar, a MultiPlus-II 12/3000/120-32 120V, and DC-DC charging with the new Orion XS. I have been following the 30A OEM Motorhome and 30A Travel Trailer upgrade paths. The kits include an ANL of 300 or 400 Amps. I think 400 Amps would be the correct fuse for the + battery to + Lynx distributor leg in my design since it is on the larger side. I am confused by your statement at 7:51 “except where we may need a 400 amp fuse like we have in the majority of our systems that have the 12 volt version of the multi plus 3K inverter charger in it”. Can you explain?

[@hoosierinthewoods]

Great video as are all of your videos. Question: Can I use a 300A terminal fuse on my 200AH lithium battery or is that too much? Thank uou

[@EXPLORISTlife]

Fuse size is not determined by the battery bank capacity. More info: kzbin.info/www/bejne/a6qQqneDesyJbZI

[@kalypsoisland]

I have 4 24v 200Ah eg4s in cabinet w busbars to which each battery is connected. Can I put one MRBF fuse on the positive terminal of each battery for protection or just one MRBF fuse on the positive battery cable from that busbar connected to the inverter, please? Thank you.

[@recoblade1465]

I know that this is a really old comment but you are supposed to fuse as close to the battery as you can and each individual battery period you shall also have a fuse on the inverter

[@JRevised]

Great video! Wondering why you didn't choose mrbf fuse for the main battery fuse instead of anl?

[@EXPLORISTlife]

They are only available in sizes up to 300A, so when we need a main system fuse size larger than 300A, we can't use them.

[@robertgiancola]

Is there a video showing how to determine the size of fuse needed? I'm running a 12v system with 400ah LiFePo, 3Kw victron inverter,60amp rover and so on!

[@thecatat7]

Ecellent video. Can you do a video about ceramic DC fuses and 12V DC systems please? In my country we get 10x38 ceramic DC fuses.

[@namechamps]

Class T are routinely available up to 800 Amps (and more than one manufacturer goes up to 1,200A). You are right though they can be out of stock from time to time.

[@EXPLORISTlife]

So, you think our wholesale suppliers are lying to us?

[@neilv6754]

New subsciber here. I have a question. I am running four 12 volt, 100 amp hour lifpo batteries hooked up in parallel going to a 40 amp mppt controller. I want to use terminal fuses on each battery. Should 100amp fuses be sufficient, or is it too big or too small on each positive terminal? I am also running all four batteries to heavy duty Pike Industry Busbars. I just want to have the ultimate in safety redundancy. Any opinions? Thanks.

[@adarvold5157]

Do you install the class t directly to the battery terminal or use a fuse block?

[@EXPLORISTlife]

All fuses need a fuse holder.

[@adarvold5157]

@@EXPLORISTlife thank you! cover also required or no? Working with 4/0 can make the small openings tricky to deal with

[@markjackson6829]

The AIC on all these fuses is dependent upon the voltage they are running at!? Thanks for the video!

[@EXPLORISTlife]

Yes. Check with the manufacturers spec sheet for each fuse for additional info.

[@markjackson6829]

@@EXPLORISTlife Yes, totally they vary a lot especially at different voltages. But some manufactures specs are hard to get ahold of, and I'm currently doing a 48v nominal RV system, so it's mor critical than my previous 24v systems. Thanks!

[@donovanturner6284]

Will an anl fuse fit in the lynx power in? The spot you would normally put a mega fuse?

[@EXPLORISTlife]

Nope.

[@dougCat]

Will any fuses restrict the current flow in a circuit?

[@EXPLORISTlife]

They don't 'restrict' in the sense that they will limit current flow. They will break and then flow will stop altogether.

[@jeffsills8284]

I'm in the process of installing my electrical system based off the Explorist 12V / 3000W diagram (with 3 x 206A batteries). I recently purchased the recommended 400A ANL fuse. Do I need to scrap that fuse and holder and switch to the T fuse setup? As of today, there appears to be several options for T class fuses available on Amazon. I don't understand from the video how much risk I am taking using the ANL instead of a class T. Thank you.

[@EXPLORISTlife]

The way I see it; is if I felt it was too much of a risk, I wouldn't be putting it in our kits. T-Fuses from Amazon concern me unless you can verify it is a quality brand like cooper/busman/eaton/littelfuse. An ANL fuse will be better than a no-name T-Fuse every time, I'd imagine.

[@jeffsills8284]

@@EXPLORISTlife Thanks Nate. I'll stick with the components I have already purchased for now. FWIW - the T-fuse I saw advertised on Amazon is from Blue Sea systems - not certain the manufacturer - expensive, but currently available.
