I am almost done! Final wiring for my 6 month project is about to be complete. I've got a lot of things grounded already. When I think of it, I think everything is connected to the power ground of my house; earth. What about my shielded cable though? Do I need to connect the one end of the cable to the same ground? Or could I simply connect it to the steel enclosure I have for all my electronics?
Also, I've got a small 5v and 12v power supply which has a ground terminal. Should this be grounded right to the house ground as well?
