Today was Spring cleaning day
I had to get new batteries in four of my UPS devices which involved a lot of plugging and unplugging. Since I was down there under my desk I took some time to vacuum and do a better job of my cable labeling.
While I was sorting cables I found one with a frayed end which I decided to keep for spare parts. In makes me nervous just looking at this thing. That’s a mains power lead with bare ends, it’s a death sentence waiting to happen! But that bit of cable with that attachment might very well come in handy some time so I will file it in its relevant drawer.
