MUYI Inline Fuse Holder - 10ga & 12v Waterproof Adaptor with 40AMP ATC Fuses

The wire is true to size and plenty long. Fuse holder feels durable but also pliable enough to insert fuse and put cap on.

Well nade

Used these inline for the power from battery to relay for headlights on my truck. Wire gauge was good, coating seemed to be good quality and trimmed easily. Installed well with heat/crimp butt connectors. I replaced the 40amp with 30amp fuses for my install the next day and found the caps are VERY VERY tight. I had trouble opening them to swap the fuses out the next day.

Good

Great quality fuse holder. I used these to protect a couple of Electric dirtbikes that I upgraded from 36v to 48v @32a draw. The wire type and gauge are of good quality. I was able to solder these into my dirtbikes and could tell immediately they are of good craftmanship. The fuse holders have a snap tight cover that felt durable, not sure if its water tight but very close. The pictures I have posted do not have the fuses pressed in all the way, once pressed down the fuse is seated very tight. I'm very happy with the purchase.

Installed easily. I wish it had options at purchase for different fuse sizes or came with a variety pack.

I used these to protect a wiring project in my van connecting my two batteries to two 12V separate power ports, giving me a choice of which battery to use when powering my 12V fridge/freezer. These matched well with some 10 gauge wire I also purchased on Amazon (https://amzn.to/35kN6Ti). In case you didn't know, these inline fuse holders should be put as close to the battery as possible. You can see in my photo that I crimped a ring connector to attach it directly to the battery. The other end was then connected via a quality butt connector to the wire that ran to the 12V port. They came with 40 AMP fuses, however you'll want to use whatever fuse is appropriate for your particular load, which in my case was only 10 amps. The included 40 AMP fuses represent the maximum for the product, not necessarily what you need, as having too large of a fuse will not properly protect lighter loads.

I am highly impressed with the 10ga 40 amp fuse holders. Other reviewers thought the wiring might be aluminum, but mine have what appears to be tin-plated copper strands. This is a very high quality type of wire with excellent resistance to corrosion, and is typically only found in marine grade products. Tin-plated copper also makes for easy soldering, which is how I confirmed the wiring wasn't aluminum.I liked these so much I'm going to order a few spares for future projects.
