There’s a specific kind of silence that hits when the generator fires up clean. You hear it humming outside, then you walk back inside and half the building is still dark. Coolers running. Office lit. Warehouse side, nothing. That’s not the generator failing. That’s the transfer logic and the panel layout telling you something you probably didn’t want to know.
The situation described in economictimes.indiatimes.com, “Baidu robotaxi outage in Wuhan caused by ‘system failure’, police say” reflects a pattern we see across commercial environments, where one piece of the system works fine and another piece quietly doesn’t. Same idea inside a building. Honestly, most of the partial-restore calls we get aren’t generator problems at all. It’s the panel wired years ago for a smaller load, with circuits that were never moved over to the backup side when the business grew.
If only some zones come back, the questions are pretty simple. What’s on the emergency panel, what’s on the normal panel and is the generator actually sized for everything you assumed it was covering? Sometimes a breaker tripped during the transfer and nobody noticed. Sometimes the ATS only feeds one section by design.
Either way, don’t wait for the next outage to figure it out. Get an emergency electrician out, walk the panels and label what’s really protected.
