I understand there are some fully electronic TS that make no sound at all.
If you have a surge guard, that will clunk a minute after supplying shore power.
My transfer switch clunks 20 or 30 seconds after the generator is up and running. No clunk when plugged in.
A little research shows that some transfer switchs clunk ( connect ) after 2 seconds of shore power AND clunk 30 seconds after generator starting.
It also said that they will default to generator if it is started, even when plugged in.
