Mains hum

Probably many community members are quite familiar to the mains hum. What effect does it have on you?

Parents

  • Being able to hear electricity puts me on edge.  I'm okay with contactor hum but I shouldn't hear sound from a breaker panel or even a fluorescent light ballast.  I guess I expect it in a substation, but the hum in a foundry makes me anxious.  Tens of thousands of amps is almost inconceivable.  I work with mains power regularly so my position is "If I can hear it, it needs to be fixed."
