At the end of that video I wonder why he turns off the main breaker to use the transfer switch. The transfer switch will isolate the circuits and prevent any feedback. shruggy


If there isn't a disconnect between the incoming electricity from the meter to the transfer switch, the transfer switch needs to be Service Entrance rated, which has a built-in circuit breaker to interrupt the power coming in from the meter.


The transfer switch used in the video has individual breakers for each circuit and the switches isolate the service.
