My understanding of this is possibly that "externe" here means external as in external to the building.
Presumably, there was a breaker - it was just in the same room as the fire.
- mardifoufs 5y agoYes exactly! But it seems like the breakers for the internal circuits were turned back on repeatedly by whatever system was doing a "reprise automatique du courant".I guess that means UPS power back ups, but why would those not be shut off automatically either by the fire alarm or just the breakers? Maybe they weren't, it's not really clear, but it's surprising to me that the breakers would not cut all current if they are damaged? Do fire-safe breakers exist?
