They just don't know what they're talking about. Mistook it for AC, where one usually wants the switch on the phase side.

Why do they put MCBs on live instead of neutral?

[–] mcz@lemmy.world 3 points 15 hours ago (1 children)

Do yourself a favor and stop arguing. Positive and negative is completely different from live and neutral. You're confusing a floating circuit with mains AC.

[–] deHaga@feddit.uk 0 points 15 hours ago

I'm not arguing. You're just wrong. Both AC and DC have high side switches for safety.

You sent me down a rabbit hole wondering if AC batteries are a thing, and apparently they are! I'm still not sure if any of the sources I found are scams, but they seem to be physically plausible. Interesting!

there are no ac batteries by definiton

[–] _stranger_@lemmy.world 1 points 14 hours ago

That certainly agrees with what I know, this is interesting though
