Unless properly tested and maintained it is not uncommon for emergency transfer switches to fail. Testing under actual conditions is not easy.
I was inspecting Lucille Packard Childrens Hospital when an actual power failure occurred. The emergency backup switch for the operating rooms failed (even tho it was tested routinely under "simulated" conditions.) The head maintenance engineer and I ran to turn it on manually.
