Okay I've made sure you can use fuses safely, as for not understanding what "9v available" means I've explained that if that's not enough at some point someone just needs to tell you that fucking off is an available option. You're being absurdly pedantic now.
I asked for clarification, which is not the same as being pedantic. Despite claiming you did, you never replied at all until the response that includes a condescending snip pretending it’s some common usage, suggesting it’s me who should know better, when it most certainly is not accepted usage.
You could have just said “oh, sorry, I just meant applying thousands of volts to a 250V fuse.”
If you want to take up a terminology crusade go fight the RJ45/whatever battle for ethernet cables (yep I call them that, deal with it!)
I call them Ethernet cables because that’s what everybody calls them. It
is “common parlance”. Saying that a load has a voltage “available” at its input most decidedly is not.
