I use 861Cs as power strips around the house, and I do notice when they're
plugged in all by themselves they emit a kind of low buzzing sound. It
isn't loud or annoying at all though, so I assume what you have is something
different.

Which reminds me. I plugged in an 861C yesterday. The
breaker seemed a bit "dodgie" as they say, and didn't seem to
want to stay on. I finally got it to stay on but when I
plugged it in I got a loud buzzing sound from inside the
"box". The switch was set to "local".
There was nothing else plugged in and the breaker didn't pop
but I didn't like the sound and unplugged it. I've never
opened an 861C up - what's inside? I would have thought it
was just A/C distribution but I guess there must be a relay
come to think of it.
I really like all those nice a/c plugs. Guess I should open
it up and see what's buzzing.
