RVBOATPAT 12 Volt Fuse Relay Box Pre-Wired Fuse and Relay Box with 4 Relays and 12 Way ATC/ATO Fuses Sealed 12V Relay Fuse Box Block for Auto Car Marine Boat

It’s a great product it fit my needs perfect …..

For the price, this is a solid box! Having the 4 relays and extra fused power slots is a bonus. Another reviewer already mentioned how it's wired so I won't go into that part, but 2x red wires are main power, black is the daisy-chained ground, white is your trigger wires, yellow goes to your relayed devices, and the blues are just regular fused power. I used this in my 2002 VW Golf for a couple sets of fog lights, underhood lighting, and a lift pump. I wanted to clean up the battery terminals. As you can see in my images, I basically connected the 14 AWG power wires together, which gives this entire box around 40-50A rating. I'm protecting the entire box with a resettable, 40A breaker as a "just in case". From the breaker to the battery I just made an 8AWG jumper which can also handle 40A. The box mounts up nicely with some M6 screws. Couple things to note: Box is NOT waterproof. So place accordingly. As well, the included fuses are cheap. Probably won't last long but I'll run them until they go.

So far, it works flawlessly. I like it. Easy to install. works well.

Product looks and feels quality, and was delivered quickly. Just do not trust the wiring diagram supplied. It states that the center fuse of each 3 fuse group (2,5,8,11) is the 30 pole on the relay. The panel I received was wired so the relay feeds are on fuses 1,6,8,12. It’s an easy fix, or just mark the relay fuses with paint pen or metallic sharpie. Also worth noting that as delivered, consider how long your runs are to battery because there are 3 battery feeds, possibly 12ga ea, and a total of 255 amps worth of fuses. The entire 12v feed side is tied together so the groups of three don’t need their own feed.

Really good unit

Was exactly what I was expecting and works great.

This will work for me putting 3 fans cooling fans in my EL CAMINO radiator 2 In back 1 in front. That way I know transmission an AC Plus engine will stay cool.this little box makes it easy to do. THANKS JOE

Wiring in product does not correspond to schematic . relay fuses are all over the place and not consistent . cable size is not large enough for 3x 40 amp relais and 255 amp total fuse size

Disappointed with the power feed wiring to the relays. They used 2.5mm² wiring as power feed to the relay, which is good for 25amp. They provide 40amp relays, so it's not safe to use those relays above 25amp. Provides a real limitation.

Worked well has multiple relays and lots of wiring. Note that all the grounds are looped together so if you want the ground side control, you will have to modify this relay pack overall the qualities quite decent and works as advertised.

Nice build, good clean wiring, leads not long enough, back wiring completely exposed (kind of defeating the purpose of having the top enclosed), unclear what type of relays are installed (turns out they are wired backwards to most typical relays), wire bundles out the bottom protrude making it hard to mount it flush on anything because the flex of the plastic housing.... Again defeating the purpose of having the top enclosed and the bottom open to the elements.

Very good product but wires to short will buy again

Très bien faite, Mais pour les fusibles de 20 et 30 amps, j'aurais aimé savoir que tous les fils sont de même grosseurs en dessous... je dois remplacer et modifier les fils pour pas qu'il surchauffe
