Common plate
Not only do I need to know where to put the common plate, inside or out, or does it matter, I also need to say that there is no house ground here. Welcome to third world electrical practice. I have asked my wife to ask an electrician why, is there something about 220bas opposed to 110 that I don't know about? Strangely, no house here in the barangay has a line from the house box to ground. None. She does not understand my concern since everything works fine and no one else has one. I'm just going to take care of my shack, line and antenna grounding. If I can get someone to run a house ground I will. Its hard for a foreigner to get anybody to do anything here especially when your "go between" doesn't see the need. Ignorance is bliss here until a good overload or lightening strike. Beats me!!!!
