Bussmann BBS-5, 5 Amp (5A) 600V Midget Fast Acting Fuse

Did it's job

We've moved into a house with a Generac 20kw Guardian and there are no techs close enough by for a routine maintenance call, so it became a "simple" DIY project instead. The main issue with the generator is that it hadn't been serviced since 2017 and was starting to show some signs of needing a little TLC. While the battery showed 12.6v it lacked CCA, meaning it was failing and causing random problems with the control board (Evolution 1.0) and short-cycling the generator even with the utility power on. I replaced the battery which resolved those issues but the air filter, oil, and oil filter needed replacing, too. "Well," I thought, "why not just replace ALL the easiest components and save myself the headache of chasing shadows somewhere down the line?", so I also replaced the 7.5A fuse in the control panel and the three bus fuses (these fuses) in the Generac service panel between the utility meter and main breaker box. FYI, the stock fuses in the bus were fine, all performed perfectly with a simple resistance test. Just by following ALL OF THE INSTRUCTIONS in the owner's manual I managed not to electrocute myself and now the generator runs like a top when called upon rather than whenever it wants to.

Not sure why they have to call this a midget fuse. Kinda disrespectful if you ask me. It's a LITTLE fuse...and here's where it gets odd. The fuse is made by Cooper Bussmann. Of all fuse manufacturers, you'd think something called a "midget" fuse would be made by Littlefuse, Inc. But no, Cooper Bussmann claims title to the "midget" fuse. Go figure. Anyway, it's a fuse and it has worked fine for the past year, and hopefully will keep up the good work for the rest of my little life.

Great seller and product. Item was shipped promptly. Would highly recommend.
