Progressive industries ems 30hw hums
I just installed a progressive industries ems30hw surge protector and it makes a humming or buzzing noise do others find this to be true.

If it's REALLY loud, to the point of being annoying, contact PI. It would be the contactor relay that hums and they are easily replaced in the field. PI has really good customer service.
EDIT
I have the 50A version installed in my MH. I can hear it if I stick my head into the electrical bay, but I can't hear it from anywhere inside the MH.
