Testing Automatic Transfer Switch

Описание к видео Testing Automatic Transfer Switch

Kohler 20KW standby generator with 200 amp transfer switch. Testing the system by turning off the main disconnect to house power. The generator activates and the transfer switch engages within about 5 seconds, powering every circuit on the emergency panel. One surprise was how long it took (5+ minutes, edited out of the video) for the transfer switch to flip back over to utility power once restored.
