Re: Transfer Switch Buzzing
I'm no electrical tech, but somehow I don't think a buzzing noise is normal.
I've replaced two transfer switches. The first simply stopped working (switching) properly, and I replaced it with an exact duplicate; an IOTA ITS-50R (took less than an hour).
I replaced the second one because there were some power anomalies and I thought it may have been the transfer switch again. It turned out to be something else, but I replaced it with a PowerMax PMTS 50 because IOTA no longer makes the switch.
End result...this is the 3rd transfer switch and NONE of them ever made a buzzing or humming sound. The only sound was when switching between shore, generator or inverter power, it would click when it made the switch... a click that was only audible when the bed platform was open.
You did not mention which transfer switch model you had, so I suggest you get the name off the cover and contact the distributor or manufacturer to ask if buzzing is normal.
