- Adding ANL Fuses to the Tigerclaw 1500w pure sine wave inverter, and also a load test on a 1500 watt quartz heater. i toss a 300 a fuse into a 2 gauge wire (pos) to TEST a load . the proper fuse/wire for this test should be about 200-250A fuse. for the batteries.My battery Red power wire is a 0AWG rated at 300amps according to its printing on the casing. Please use the chart below to figure out your rating/wire size for your loads.
my peak load on the inverter is 3000 watt, thus this max rating test with a300 amp fuse.
The fuse rating is "generally" (watts/volts) x 1.25, example: lets say 1500 watts normal run usage, so 1500 divided by the volts (12v dc in my case) is 125, now x1.25 = 156.25 ,
I Personally just use a 10:1 rule of thumb ratio so 100 watt 1 amp fuse etc.. so 3000 watt load on my peak is 300 amp, give or take a few. i tested it with a 150 on a 1500watt load and the moment it went over 1500 watts the fuse popped, so it calculates close enough for me. but for those that need official charts, scroll down below the links.
here is some science and data..
The fuse size should be based upon the amperage draw of whatever you are running, not the watt rating of the inverter SIZE YOUR FUSES ACCORDINGLY!
A general rule for any Anneaaled CU Wire, also those American Wire Gauge charts are for chassis wiring. and they are always downgraded. stranded vs solid core, voltage drop, temperatures, thickness, thermal conductivity all play roles. its such a short run, its totally capable. those ratings are just a rule of thumb. the marking on the cable will display its "rated limits" just don't use cheap a$$ cables.

Thank you and God bless America! Thank you patriot!
Thank you. Found the glass fuse holder set. Very much appreciated.
Not sure where you got your wire sizing guide numbers from....they seem overrated/over inflated. E.g. 2/0 AWG copper stranded cable (i.e. ~67-70mm squared) is usually rated up to ~280-290A (@90 degrees insulation) MAX, or even lower according to some. I have never seen 2/0AWG rated at 400A. Running close to 400Amps through 2/0 AWG cable will cause immense heat.
If you have an aftermarket car audio system. Do not connect the led fuse holder under the hood. You’d want to connect it to your secondary battery if you have one. Since the amplifier(s) draw the most power that’s where you would want to measure for voltage drop.
It would really be helpful if you showed your bench work. I came to see How To... slow the camera spinouts, yikes!
Thank you
When you said;300 amp ANL fuse I paused video went into O Riley's and ordered it for $7.50.with a 24 hour delay between Salt lake City and Denver I'm using this afternoon the 140 amp battery isolator ( placement for now was going before a 2 gauge wire feed with at least ten feet of wire through firewall before going into a storage batteries system with upgrade s to my inverter system starting at 1000 watt's
Then add another 300 amp fuse from my additional 100 AH solar panel and 500 watt converter?
I hope that I'm correctly understanding these lessons
you may want to downsize your fuses if your max is 1000 watts, mine is 1500/3000, so redneck math of 10a for 100 hence 300a for 3000 is the MAX rating. my fuses are direct between the inverter and the battery, I too have a isolator on off switch that is direct, no fusing internal, like a bus bar you can move off or on, it is on my negative battery terminal from the inverter. figure out what the max load you draw from your inverter and size it from there, if its 2000 watts, and your BATTERY size cables are large you can run a 200 amp fuse, test it, get some multipacks on ebay, they are cheap, a few sacrificial blows to test your range. i have 900amphours in my battery array so my max load is 300 amps. yours may vary depending on your max load and battery amphours, remember cable length also can drop the voltages too if its a long run. -- the fuse rating is generally (watts/volts) x 1.25, example: lets say 1500 watts normal run usage, so 1500 divided by the volts (12v dc in my case) is 125, now x1.25 = 156.25 , I just use a 10:1 rule of thumb ratio so 100 watt 1 amp fuse etc.. so 3000 watt load on my peak is 300 amp, give or take a few. i tested it with a 150 on a 1500watt load and the moment it went over 1500 watts the fuse popped, so it calculates close enough for me.
@Chris Edwards Restoration great info brother
I enjoy everything about this video EXCEPT you move the camera around too fast.
im working on improving. !
Chris, i have a 1000w pure sine inverter in my RV that powers the refrigerator. I foolishly bought a new battery and installed it backwards. Do you think the inverter is junk? It has an ANL fuse
Fuse would have popped or the inverter has polarity protection as most do to prevent that exact issue
Hey Chris, is it fine to use a 300amp fuse eventhough I'm only needing 150amp? Thanks in advance
depends on the peak load, my peak load on the inverter is 3000 watt, thus 300 amp fuse, the fuse rating is generally (watts/volts) x 1.25, example: lets say 1500 watts normal run usage, so 1500 divided by the volts (12v dc in my case) is 125, now x1.25 = 156.25 , I just use a 10:1 rule of thumb ratio so 100 watt 1 amp fuse etc.. so 3000 watt load on my peak is 300 amp, give or take a few. i tested it with a 150 on a 1500watt load and the moment it went over 1500 watts the fuse popped, so it calculates close enough for me.
Chris Edwards got it! Thanks man! Been a great help!
Where do you connect the display wire too?
ground or the negative battery terminal
Hi. I ordered this distribution block for my car amplifier. Does the voltage indicator LED light up during load or all the time if terminals are connected? Do you think this will discharge the car battery when car is not in use because of the voltage LED?
Not at all it only uses milivolts to show the voltage. I removed ky
Solar feed for over a werk one time while doing battery swaps and never had any issues. Enjoy!
@@ChrisEdwardsRestoration Thank you :)
@@ChrisEdwardsRestoration hi i installed this very distribution block on my car but it does not display the voltage. only lights up two little red dots. what could be the cause of this?
Improper grounding or you have a poop unit. Is the fuse in? All connections tight? Just ground the little wire to metal anywhere
@@ChrisEdwardsRestoration Everything is fine. I was wondering if there is a chance of battery discharge due to lighting of the voltage indicator. I understand it consumes very miniscule amount of power but just wanted to be sure in case i leave the car parked for a month or so.
Great video! i got a question regarding the AWG 2 cable. Its rated 300amps. But when I look it up on any awg chart online..it states that awg 2 can only support 94amps. And only a 4/0 wire can support 300amps.
that is a general rule for any Anneaaled CU Wire, also those American Wire Gauge charts are for chassis wiring. and they are always downgraded. , stranded vs solid core, voltage drop, temperatures, thickness, thermal conductivity all play roles. its such a short run, its totally capable. those ratings are just a rule of thumb. the marking on the cable will display its "rated limits" your good! just don't use cheap ass cables. and i doubt we are pulling that man amps on a solar / battery setup anyway.
@@ChrisEdwardsRestoration I looked at the digital fuse block link. They are 200 and 300 fuses. Is there anything more in line for 30 and 40, maybe 150 amps with that cool readout feature that you've seen? I am setting up a solar array, yup
They come in all sizes from 10 to 500 amp
@@ChrisEdwardsRestoration thank you. I was thinking only for the solar run to controller just for gee wiz. Glad I found you😊
My big fuse is the anl from battery to inverter. Due to my amp hour range and number of batteries while parallel do have some capable amp hours (900) my inverter is a tigerclaw pure sign wave 1500/3000 startup load. I have several other msw inverters from 400 to 2500w. I have three 150w 12v panels on my roof now controlled by my hqst pwm controller. Each of My solar panels have mc4 in line fuses at 15amp by renogy.
Hi Chris, where did you connect that black wire to from that ANL fuse holder?
to any negative terminal on the battery
Thank you.
Or ground
From what i have read ANL fuses arent' for inverter install that they require A T type fuse must be used .
been working totally fine for years... popped one when i overloaded the batteries w multiple inverters, so they work.
@@ChrisEdwardsRestoration and they don't get hot? Good to know
Never
Now I'm wondering if they are mentioned to use before the batteries isolator ?
Can you PLEASE tell me where to buy the glass fuse set with the led readout? I have been searching but unable to find anything like it. Thank you so very much, cheers Yvonne
ebay! search for ANL fuse holder LED like this one for example. www.ebay.com/itm/264752080213
This fuse good for solar sir
nice... too too much camera movement
old pre tripod video.
My 3000watt invertor has a surge of 6000watts am I not able to use that much with a 300amp megafuse ?!?
I am 1500/3000 i have a fuse close to my max amp range
Got a link to the fuse holder with display?

@@ChrisEdwardsRestoration Thanks!
if that link don't last, just ebay/amazon ANL fuse holder with display
Where do you put the blue wire that's on a 0 gauge fuse holder
its a ground for the digital lead
@@ChrisEdwardsRestorationhey I have a black and blue wire on my fuse holder ? Does blue mean ground and black means ?
Am I correct thinking if I have a 2000 watt inverter , I need a 200 amp fuse.
Not exactly , make sure your wire diameter can support the wattage. otherwise it would get hot and possibly melt/burn
Chris Edwards that would mean I need 0 gauge wire. The inverter company tells you to use 8 gauge. So confused.
No. You are basing your math on the wrong factor.
The fuse size should be based upon the amperage draw of whatever you are running, not the watt rating of the inverter.
If the watt draw of, say an induction cooktop plugged into your inverter were drawing 2000w then yes the fuse would be 200A
sure wish you would’ve included putting the wires in the ANL fuse.
Its just a hex key screw that tightens them down. Super easy
@@ChrisEdwardsRestoration I had figured it out.. I was super confused! lol. Im a 20 year old girlie with no experience with electricity whatsoever. I do have another question, does it matter where i cut the wires when adding the anl fuse in, or could i add them in where ever on the positive line?
Nope can be anywhere in the line. Usiallly closer to the battery or inverter. Your call
well, a 4AWG WIRE can handle 100AMP up to 3M max ...your fuse is 200A it means your fuse is just a decoration the wire will burn and the fuse standstill :(
well heres the equation
wire size =load in amp X 1.50AMP
fuse size=load in amp X 1.25AMP
good luck
hence the title "test"
Thank you Ramahi, THAT'S the information I came for
I didnt see you brow up fuse
Thats a good thing
slow down the camera, im dizzy
sorry , old video, learned alot about filming in the future.
geat vid thanks for info i subscribed hope i get it back lots of info thanks again very helpfull
Where do you connect the display wire too?
the display wire is just a ground, it gets its power from the main line, so to the negative cable.
@@ChrisEdwardsRestoration great thanks! What size anl fuse do I need for a 1000rms amp? The amp itself is 105 amps. 2 gauge wire
@@MegaBluecream 100 , but it depends on the peak load, my peak load on the inverter is 3000 watt, thus 300 amp fuse, the fuse rating is generally (watts/volts) x 1.25, example: lets say 1500 watts normal run usage, so 1500 divided by the volts (12v dc in my case) is 125, now x1.25 = 156.25 , I just use a 10:1 rule of thumb ratio so 100 watt 1 amp fuse etc.. so 3000 watt load on my peak is 300 amp, give or take a few. i tested it with a 150 on a 1500watt load and the moment it went over 1500 watts the fuse popped, so it calculates close enough for me.
@@ChrisEdwardsRestoration so the display is always on..even if u not turn on the engine/acc?
Yes. Uses very little current to show battery voltage. Been running for years now. No issues
