WUPP Waterproof 12 Volt Fuse Block With LED Warning Indicator For Car, Marine, RV, And Truck - Includes Fuses And Negative Bus Fuse Box Review

When I got this, I was pleasantly surprised because it seemed well made and designed. I spent a couple hours wiring everything up to it, turned on the power, and seemed like it worked great! Then I decided to test what happened when I removed a fuse (to simulate a blown fuse). Insanely, when this happens, the "blown fuse” indicator does light up - BUT - there is now 2-3V present on that circuit! Meaning it’s still connected to power! If the output of the circuit is not connected to anything…

This is a nice little unit. I put my meter on it and checked it out and it is indeed as specified.I did find that if you hook up an LED to it and pull the fuse out that there is just enough of an induced voltage to just barely light it up.I ended up not using it for my project but will hang on to it for my next one as I see this as a very useful and handy unit to wire up a boat, RV, or who knows. It’s definitely cheap enough.

I used this to be placed inside of a weatherproof box to provide a junction box for power and ground to my utility trailer. Some trailers have no junction box and if you want to add lights to your trailer you can make something like this. I added weatherproof grommets and had to use a dremel tool to shave down the sides a bit so it would fit inside the box. All wires heat shrunken for securing better inside the box.

I’ve looked around at different store and couldn’t find what I wanted. Found this great fuse block, completed my electrical in my motorcycle trailer. Thanks

This is a great fuse block for an auxiliary power out to accessories on a car or truck. Also worked well on my boat. Thanks for attention!

The only issue I had is the cut out on the cover. It would have been better to have options on where the main positive and main negative wires come in from.

I had difficulty in securely installing the fuses. They didn't "click" into place readily. Could have been me, not sure. But they all worked and continue to work well.

ground bolt was loose had to take the back off , found the bolt not seated and loose. I glued it reassembled it . but ordered Blue Seas to replace it . better product always. i will use the repaired fuse holder on a less crictrial project

Just got my power Distribution Block and even though i have not used it , it seems very well made for the price my only gripe is the Fuses are as cheap as you can get and doubt they will last long. but it gets you up and running also my other Gripe is the box came open in the ebay bag sure hope it wasn't one that was sent back or someone messed over that worries me

Bought this to clean up wiring under the dash of my vintage car and add more fuseable links. It looks pretty good. Nice compact size. Construction is fair. Comes with some very cheap blade fuses (that I did not use). Two biggest issues: 1) blade fuses do not fit very good. Some of them took some effort to get the fuse in, to the point where I broke a fuse. 2) the plastic cover is useless. Supposed to snap on but fit is so loose it will not stay on. Mounted my box inverted and the cover just…

Used on my diy build ebike battery connections, have about five (5) wires both pos. & neg. coming from the lighting and horn (car horn) running to battery each with spade connectors and a 12v battery with pos. & Neg. spade terminals and using chair & piggyback adaptor for multiple connect, now only have one pos. & neg. wires directly from battery to fuse box works like a charm and much neater, was looking for a terminal box only (didn't need fuses, have inline fuses already, but still works…

I mounted this on the cover of my vehicles existing fuse panel in the engine bay to use with accessories, light bar, battery tender, ect. It works great and has a plastic cover to protect the fuses from water and debris.

Used this in my golf cart to wire accessories. Easy to use comes with fuses and labels. All in all decent value. Gets the job done.

Separate fuses for power distribution.Only down side it would be nice if there was a little more room at the main power supply connector to be covered inside the plastic shielding. Box is capable of 100 amp distribution dependent of distance from battery main wire needs to be 6 awhile or larger coupler will be larger that the space provided.

I purchased this fuse block to use in my shuttle bus conversion to wire in my 12v system. This is a straight forward block, and is of good quality at the price point. After wiring it up, it works as advertised and I trust it to relay stable, consistent power in my bus and not burn it down. I recommend this product.

Looked at a variety of fuse boxes and decided on this one. Price was very good and I didn't need a lot of hook ups. Easy to tie into (fan, lights, and USB ports) and all is working well. It was shipped quickly too. Glad I got this one!

This is a nice size fuse block with a perfect set of features for a small boat. The main positive and negative terminals however are jammed in the "tight” position "as received.” It is possible to spin these terminals out of the plastic case with very little effort. I think? I may have avoided damaging my unit by watching for the plastic deformation and ultimately used a narrow needle nose plier to grasp the lower "nut” while backing off the top nut. I am not sure this will be an option once…

This fuse block is all you should ever need for all your Auto, Boat, or Golf Cart needs. It's well made , compact, and looks great. I should have purchased this long ago instead of adding fuse connectors to my projects.

Just what I needed for my wiring setup with downriggers, fish finder, bilge pump, phone charger and lights. No more splicing wires on both battery terminals. No more in-line fuses that comes apart with age.

Came with plenty of fuses, all the terminals look good.It's currently being used for running board lights for my Ram, it's handling everything just fine so far.Only complaint with it was the plastic cover was slightly bent on arrival.Other than that it's great.
