Cooper Bussmann BBS-5 Buss Midget Fuse, Fast Acting by Cooper Bussmann

I used this on my Generac Transfer Switch Sensing lines. My power company had a major power surge that ended up blowing out a bunch of appliances on my road. Took out the internet for a week. This was a direct replacement and fit perfectly. No issues with function.

this item is exactly as described

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.

Perfect replacement fuse for my generac auto switch panel.

fit and worked perfectly and much lower cost than others.

Hard to find fuse was as pictured and then delivered quickly.

Good Quality

Pricey little guys but they only need to be replaced when they do their job.
