Review on Jamgoer DC 10 PCS 30 Amp Auto-Reset ATM Mini Circuit Breaker Kit: Reliable Marine RV Yacht Battery Trailer fuses assortment for Boat, Truck & Bus by Justin Rasmussen

I have a classic Ford pickup and although I like it, like many old cars it has some features. For example, when I switch from the air conditioner to the heater, the 20 amp mini fuse usually blows. This gets boring quickly, especially in spring and autumn when I might need heating in the morning and air conditioning in the afternoon. It's not just about the cost of the fuse, the problem is changing it every time. I always have a fuse box in the glove box. I didn't even know there was such a thing as a fuse box breaker until I found it. The mini fuses themselves aren't that cheap, so at around $80 apiece ($17.68 gets you 10), it's not a bad deal. on the photo. It hooked up right away, and then I tried switching from AC to heat and back multiple times. This usually causes an instantaneous surge of electricity that blows the fuse, but I couldn't get it to do it this time. By the way, I spoke to the mechanics when the truck was tuned and they say that sometimes it only happens on older cars. There's no way to track down the cause - it's just a surge - but they warn: don't set the fuse to a high amperage rating! You don't want to burn the wiring. But as I said, blown fuses are obsolete. The description says these fuses have an "auto-recovery feature" so I can only suspect a momentary overload that blows the internal circuit breaker and then turns back on. - and since the overcurrent is just a flash, everything works as usual. I get either air conditioning or heating with no problems. So far so good and if this continues to be true my headache will be gone and I recommend these mini circuit breakers!
