Todd, I have exactly the same Contactor Box. I'll try another approach to explain this device.
This Contactor Box houses 2 Contactors (or Relays). It is controlled by a Switch (on mine) by the Driver's right Knee and has 3 Positions...Shore-Off-Generator. This is what would be referred to as a Source Isolation Panel.
I have heard a buzzing noise on occasion from this Box although usually when the Voltage coming in is Low. (look out here we go)However over time the Electrical Solenoid that activates the Contactors can have some wear. This is usually only in the Solenoid portion however the Contactors can have some pitting and this could also create some noise.
Are you trying to use a regular house outlet or 15-20 Amp Receptacle?
