If a 10 gauge wire can handle up to 30 amps. Why I would need any fuse if I don't go over 30 amps even if it shorts. These only produce 8.3 amps.

NEVER go without a fuse! Cheap insurance! Why would you not want to install a fuse? $5 buck?

Don't know what kind of system you have but we have ours on a RV and one wire came off and it cooked the two fuses on the inverter, cooked the inverter, and we had reverse polarity. So for the price of a 5.00 fuse that I could of had at our leads from the batteries it would of cured the big expense and headaches.

I have two of these panels mounted to the roof of my 5th wheel camper. I did not install a fuse in line. I did install the "controller" which is supposed to prevent overcharging of the batteries and prevents discharge at night. I have not had any negative issues with these panels.

I have 5 of these and did not install a fuse. I have discovered that for practicle installs >10 feet of wire, you need 6ga or double 10ga to reduce voltage loss. This is VERY important if setting up an MPPT system. Its still important for PWM. You can never have wires that are too thick.

I would always use a fuse in case the diode should fail in the panel or failure of your battery charging circuit/batteries. I've melted plenty of wires to know the value of a fuse. I also need to practice more of what i preach :)

The assumption would be 20 amps. 10 ga wire is rated for about 30 amps but there aren't any 30 amp single pole breakers that I am aware of.

It is only 20 gauge wire and it would not handle 15 amps for any length of time. There's an inline 15 amp fuse auto style fuse which in it's own right means 15 amp max short term. I wouldn't use it for more than 10 amps.

I used a 10 amp fuse and it worked very well. My amp meter never pulled more than 5.5 amps in any mode. Hope this info helps.

Someone is 'guessing'? I wouldn't call that an answer. And 20, maybe 30 amps out of '18 gauge' wire? DON'T EVEN TRY IT!

You will be able to run 10 amps from each plug for your total of 30. You need to check the amp rating on what you will be running.

the whole block is rated at 100 amps, so the wire gauge and fuse you use should be determined by the load you want to put on the block (up to 100 amps) and the length of the wire run to the battery from the block. 8 gauge would be adequate for a short run, 4 gauge for a longer run up to 20 feet or so.

The only thing I could find on fuses was in the book. Tow vehicle Must be Capable of providing 12V @ 20Amp for Electric Brake Applications, Up to brakes (3 axles). If it blows that fuse than I'd be checking for shorts or some other over load. Sorry I can't help more, so far mine has work fine.

Yes it depends on the load once again. Ive never gone wrong with 2awg or true 4awg. And I always have 60amp fuses in the same holder as listed above. It handles just fine. A tip too for connections:buy some dialectric grease and coat it on, helps with corrosion also with actual electrical connection. Always leave enough room for wire to "wiggle" and move. Make sure your ground is sanded at the least and very strong.

I personly ran two 10 guage wires based on what I was connecting. it is rated for up to 100 amps on a standard 20' foot run of wire from the batteries to the fuse block You could go a single number 8 or even a number 6 cable run. there is a stud terminal connection so you can fit just about anything on it with a ring connector on the end.Good luck.

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.

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.

They were designed for 30 to 40 amps according to the manufacture. I think you are thinking like house wire that is AC. With DC if I remember correctly you can run 30amp through 16 gauge for approximately 5 feet. But longer distance require lower gauge. 10 gauge is.good for a run of 20 feet. But I agree thicker the wire the better.

I don't see why not. You just put the 15 Amp fuse in place of a 10 Amp one. Just make sure you're not overloading the circuit as the wiring is probably designed for certain combined amperage

Hi Janet, wire gauge is 16 AWG, comes with a 5 Amp fuse. but now I use it with one of 10 Amp. through it start to run a 120V power inverter 375W

Ideally, you should use a 200amp fuse if I understand your question correctly. Wiki American wire gauge for more info.. Hope this helps.

judging by the wire size not a lot i wouldnt go more that 10 amp unless you use it to drive a spdt 30/40 amp automotive relay
