When this happens, it stops the electrical power from flowing through the electrical circuit. Fuse rating is the amount of current needed for the fuse to blow or break. You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. If I’ve missed anything or left anything out, please correct me through PM, and I will correct the tables. Personally, I would go with the 20 gauge wire and a 2.5A fuse.

That table tells you that you should have no smaller than 21 gauge wire for your circuit. Put 1.88A into the top table in this post. Based on the table above, each transformer draws 700mA, each Superflux LED draws 80mA, and the LED strip draws 80mA If you want to put all of these on a single circuit, you’ll need to know the current. Say you bought a cold cathode kit for each side of the dash (2 Transformers), 5 superflux LED’s for your vents, and a 4.7″ Flexible LED strip for your center console. You can use this value in the fuse size chart above to determine the minimum wire size required. Add the values and divide by 1000 to get your total current in Amps. To find the total amperage in your specific installation, refer to the table below.įind the items that you’re installing and their current requirements. Because of the low-current nature of the products at Oznium, most of the products, and the table that I’ve developed, have current listed in milliamperes or mA for short. One of the first questions to ask when planning your installation is what size wire to use, which will later determine what fuse to use.ĭon’t worry if you’re lost, you’re at Oznium, we’re helpful here.Ĭurrent is measured in Amperes, abbreviated to Amps or just the letter A. So you just bought your stuff at Oznium and are getting ready to plan your installation while USPS gets it to your door. Ex: 5A,10A,15A,20Aĭetermining the Total Amperage of your Circuit DO NOT EXCEED THE VALUES ON THIS TABLE! Common automotive blade-style fuses exist at 5A-20A in 5A Increments.

Take the maximum current value obtained from the table and find the largest fuse you can find that still falls within the limitations.

The fuse size should be based on the SMALLEST wire (largest gage number) in the circuit.įor those of you who want to get right down to business, let’s not waste any more time, here’s how you’d go about calculating fuse size correctly in 3 simple steps: Actually, the load of the circuit should have nothing to do with choosing a fuse size. One common misconception about choosing the correct fuse size is that it’s dependent on the load of the circuit. It’s also a great idea to get an ATC fuse holder to protect and mount your fuse. For your fuse to do its job correctly and protect your wires, it should be rated about 1.1 to 1.5 times the rated current value. Things could get really ugly really quickly, so to avoid all that mess you’ll need to ensure that you get the right size fuse for the job every time. The main function of a fuse is to protect your wiring, but in order to do so, you’ll have to get the right fuse wire size from the start, too low and it’ll blow, too high and you’ll end up doing damage to the whole circuit!

This is an in-depth fuse tutorial explaining everything you need to know about fuses and how to size a fuse. Most people get caught up on fuse wire size but once you get the hang of it, it shouldn’t cause too many headaches.
