what size fuse should i use

2.1 Amps max output at 5 Volts = 10.5 Watts = 0.875 Amps at 12 Volts so a 1 amp fuse would work just fine.

I'm using the socket for charging my iPhone and/or GoPro in my kayak and haven't had any issues using a 5 amp fuse. I want my fuse to blow before any damage to my equipment. If I blow a 5 amp fuse, I may try a 7.5 amp to see if it'll keep up with the load.

P.T. Bailey's answer is correct. And wow... lots of answers by people who have no idea what they're talking about here. Blue Sea Systems specifications state "2.1A DC (total)", not 2.1A plus 1A. And Bailey is correct, that's at 5 VDC, which is 10.5 Watts, which is 0.875A at 12VDC. Another way to compute it is 2.1 X 5/12 = 0.875. The parasitic current draw of the device is just 15mA so can effectively be ignored. I'd use a 1A slow blow or a 2A fast blow. I would NOT use a 5A or 7.5A. Keep in mind that 7.5A at 12VDC is 18A at 5VDC. To make matters worse, a car electrical system is rarely regulated at 12VDC. It usually runs no less than 13.5VDC, at which voltage your 7.5A fuse equates to 20.5A at 5VDC. P.T. Bailey's answer is correct.

These are standard car fuses and the amp ratings are for 12 volt DC circuits. To use for other voltages would require a calculation to determine the amp rating of each fuse. You know the formula is: watts are equal to amps times volts. So a 120 watt load at 12 volts is the max for a 10 amp fuse. Now that same fuse in a 24 volt system with a 120 watt load would max out at 5 amps.

The dimensions of the fuse block are 5"w x 3 1/2". Internal fuse block measures 3"w x 2 1/2". The smaller (metal 6-connector) measures 1 1/4"w x 1 1/2". These measurements should answer your question.

The fuse should be smaller than the smallest amp rating of everything in your system. There is no single right answer. This charge controller maxes out at 20 amps, so that's an upper limit on the fuse you should use. The other main consideration for fuse size is the type of wire you're using, but the fuse is also limited by connectors, switches, inverters, etc. The purpose of the fuse is to blow BEFORE anything catches on fire.

mini blade fuse are smaller in width than ato fuse these use regular size fuse in the little fuse

Keep the inline fuses. That's the way the engineers designed them. Your battery box fuses are fine to use in conjunction.

Honestly im not sure. But i have a 10amp inline fuse fore it and it seems to work perfect. I use them everyday.

If you mean 2 gauge sized wire, this fuse block will be fine. I question using that size wire for 400 amps, however since #2 wire is not suitable for that current level. Perhaps the 400 amps is instantaneous and you know, from experience #2 wire will suffice, then this fuse block will work. The bottom line is you have to match the wire size to your continuous current rating then see if that size wire will fit this particular fuse block.

Ok here you go it uses 10.5 amps you can use a 12 amp fuse if you can get it or 15 amp fuse ( check you wire size)

That is really based on expected load. Recommend you check what the LED lights are rated, and you can actually od a search for the right gauge to use. I would expect you wouldn't want to pull any more than the fuse is rated. sounds like 20-22 gauge is what is used on the adapter any way so that should work.

Only use the GP-DC-KIT3 if you are running 24 Volts. A GP-DC-KIT5 would be suitable for 12 Volt applications. Go Power recommends this GP-DC-KIT5 kit, or to use 10 feet or less of 4/0 Cable with a 400 Amp fuse. This kit includes 10 feet large gauge battery cables, tie downs, the appropriate amp inverter fuse and mounting block.

you need to use a big gauge wire size (I think I used 0 or 2, and they make really flexible ones now that are nice if you plan on running it around corners. The manual says 4 gauge is the smallest you can use). I'm not sure about fuses... I bought a couple of big fuses but didn't end up using them. I've just looked over the manual and it does show a fuse installed between the positive terminal on the inverter and the battery, so I better make the change. This inverter has been really great, though.... I might even get a second one.

Oh the fuse is huge, I think 50 amps. You can get a smaller fuse though and substitute it into the gold plated connector

10 amp. in a fuse link should be fine. If it pops after extended run time, bump it up to a 15 amp. Remember the fuse should be the weakest point in the circuit so any fuse should be OK if you use the right wiring and nothing gets warm.

Go to Google and type in the serial number of the fuse. I've always had a lot of luck doing it for light bulbs, fasteners, etc. Fuses shouldn't be that hard either. Other than that, try contacting the manufacturer. Hope this helps.

I used the Knu Konceptz KCA 4 gauge kit. Any wiring kit with an 80 amp or larger fuse will work.

im using a 80 amp gold fuse seems to be working good now for my 1000 watt amp powering two 12" speakers but i think u can go lower to mabey even 20 amp idk
