Review on 🔌 MuHize 10 Gauge Standard Inline Fuse Holders - 2021 Upgrade Vision, 12V Fuse Holder with APR ATO ATC 40AMP Standard Fuse (4 Pack) by Andre Belitz

I used 20-25A in a backup application with the included 40A fuse. There is significant resistance in the battery holder, which after a few minutes causes the holder to become too hot to touch. I have to see if only one of them has problems. The ends have double crimped spades for the F2 battery connector which I use in another 25A application with no noticeable heat. Edit: I measured a drop of about 100mV at 20A with a 40A Bussmann fuse. I tried two different fuse holders to make sure it wasn't a manufacturing defect. That's over 2W loss at 20A, or twice that at 40A, which is probably enough to melt the insulation. Due to the poor quality of the fuse holder they are completely useless for more than 5 or 10 amps as they won't fit 10AWG wire. Complete crap - do yourself a favor and order a brand.
