Mains can be killed at a distance, in the doorway, by someone not even getting near the machine.

Losing a mains "all stop" (and a mains breaker at that) seems to me to be an odd safety choice.

I think cordless tools make a lot of sense for anything you have to hold or direct with motion. I'm just not convinced by the need elsewhere, particularly on the most dangerous tools.

I guess a door-located emergency-stop button is standard in your country? It's not here. I've never seen one in either a home shop or a commercial cabinet shop.

That's interesting. I wouldn't walk over to the door to isolate power before changing a blade, for instance, I'd just unplug the cord or the battery. That lets the rest of the shop continue running while I have my hands inside the one specific machine.

I don't know if it is a standard, but I have seen them a fair bit (UK).

I did say "additional", though.

I mean, yes, you'd want to be able to locally isolate the power as well, where possible.

But when the device is capable of running cordless, you're losing that scope.
