WUPP 20A Motorcycle Fuse Block with Relay Box Kit, Small Automotive Fuse Block with 4 Circuits Mini Blade Fuse Holder, 12 V Distribution Fuse Terminal Block

Used this in a motorcycle build where "eliminating extraneous parts" was a high priority. Of course you can't run a starter through this relay, but the main relay and lighting relay are gone thanks to this ingenious little device. This saved a considerable amount of wiring and duplication of effort to get this machine running.When ordering fuses, make sure to choose LOW PROFILE MINI FUSES, not "mini fuses".

Great Micro Fuse Box. Very small and fits perfectly with in a 2021 Honda Goldwing's side panel. The only thing that concerns me is that I have to keep it hot (accessory trigger wire to positive) as some of my accessories need to be always powered. But with it wired hot, and not with accessory switched, keeps the onboard fuse box relay and the fuse monitoring lights on all the time. This concerns me a bit about idle power draw.

Fits perfectly next to the battery in my 2012 BMW 650GS. Doesn’t draw any current when it is off. Measured 0 microamps. 90 ma when on. Works perfectly to power my aux lights triggered off the gps connector. Seriously easy to use.

Before I retired I worked many years in industrial automation. I know the benefit of having isolated circuits. It makes working on parts of the electrical easier, since you don't have to power off everything, and also makes troubleshooting easier if you have a short.Most people just slap in wire nuts, fuses, and a healthy dose of electrical tape, but the end result looks terrible. This fuse block allows for a professional looking installation.

I got this to use as a way to tap into my ignition(Acc) and power my devices only when my motorcycle is switched on. I liked the fact that the display will tell you once switched on that a particular connections fuse is bad. (illuminates red). If it is working it illuminates blue. The install was pretty straight forward. Connect to the battery terminals and connect the third wire (ACC) to the applicable ignition powered wire.One thing I did not like was the length of the ACC wire. I also found the length a little too short on the battery leads. I had to cut down the sleeve about 1 inch to let it fit my motorcycle batteries perfectly. Based on where I was tapping into my ACC connector I had to extend that wiring by at least 12 inches to tap into my ACC connection.The instructions could have been better. There is no explanation on how to use the accessories included in the packaging for a novice. I was also unsure if the 20A rating meant that I can go a max of 20A in each slot or 20A across all four. I did appreciate the fact that it included extra fuses and that they were low profile in nature. It included four 5A fuses, and one 3A and one 2A.I also wish it was waterproof. I generally don't ride in wet weather but I don't want to worry about exposure of the fuse box to moisture, etc. I will have to figure out a way to seal it. Overall, this device allowed me to add my USB charging accessory and gave me additional slots for making it easier to add ignition powered devices in the future.

The WUPP 20A Motorcycle Fuse Block with Relay Box Kit is designed for managing and distributing electrical power in motorcycles or other small automotive applications. Here’s a detailed review of its features, benefits, and potential drawbacks:Features:Fuse Block Configuration:4 Circuits: Equipped with four circuits, allowing for the management of multiple electrical components or accessories.
