My BX750MI-GR has saved my precious data on two occasions. Earlier this year, my seven year old, well used waffle iron shorted, popping loudly and sparking quite brightly in the process, probably because of all the gunk that had accumulated inside its less cleanable interior over the years. That not only made my breaker trip, but also blew the 16 amp main fuse. The UPS kicked in immediately, making a klick and a beep, which felt amazing. That was my first time ever.
As for the second time, see this post.
I used to live in a house with 1800s ceramic wiring in the walls. You bet a.UPS saved my setup more than once. I have 3 now.
Holy crap! I’d LOVE to see a picture of those wirings if it isn’t too much of a hassle for you! I’m fascinated by all things historical and I love to take quick but deep dives into how especially technology has evolved! 😁
Sounds like knob and tube in the walls. Old code terrifies me. Live-front-end switching and the like. There’s a victorian manor house near me that featured on Tom Scott and talked about having to light lamps with a bath of electrified mercury.
