Review on 🔌 MUYI 10ga Fuse Holder 2 Pack: Waterproof 10 Gauge Pigtail Blade Fuse Relay with 40AMP ATC Fuses by Aaron Martin

I used them to protect a wiring project in my van by connecting two batteries to two separate 12v power outlets which gave me a choice of which battery to use to power the fridge/freezer should use 12V. They go well with the 10 gauge wire I also bought from Revain (https://amzn.to/35kN6Ti). In case you didn't know, these built-in fuse holders should be placed as close to the battery as possible. You can see in my photo that I crimped the ring connector to attach it directly to the battery. The other end was then connected via a good quality butt connector to a wire that went to the 12V socket. They come with 40Amp fuses but you should use the fuse that is appropriate for your particular load, which is what's in my case only the case was 10 amps. The supplied 40A fuses are the maximum for the product but not necessarily what you need as a fuse that is too large will not properly protect lighter loads.
