I was talking to my mortgage broker today and he said:
"Why does my wiring hum?"
I asked min to describe what he had plugged in. He said:
"I was plugging in Christmas light and kept blowing the breaker so i got into the panel and changed the breaker. But when the xmas light are on you can hear a low pitched hum."
I said:
"What size breaker did you replace the old breaker with and he said 30 amp"
<b>I almost fainted</b>............
I explained to him how dangerous this was and to immidiatly take out the 30amp breaker and put the 15amp back in.
Now I've long suspected that if you exceed the amperage rating of a conductor it vibrates but have never tested this. Anyone care to confirm this?
