		interestica on March 12, 2021 \| parent \| context \| favorite \| on: San Francisco’s Secret DC Grid (2012) I had no idea about this. Can it damage things that won't work (eg things with AC motors). I've been building out electrical in a campervan and always wonder if there were DC equivalents to a lot of things.

Yes. AC motors will normally blow their fuses immediately.

But a small AC motor (eg. a fishtank water pump) will burn out before the fuse blows.

Surge protector strips sometimes have isolation transformers. These will also blow their fuses immediately.
