ground feedback loop from different grounds can happen.. shows up in electronics , like computers , stereos , fluorescent lights, some incubatorsI'm not an electrician but no matter what source anyone goes with i cannot stress using conduit enough! Not a flimsy plastic either, something sturdy and chew proof. Conduit from beginning to end, no plastic outlet boxes metal with covers are going to be your best friends. Does not hurt to install a ground rod either. Mice will love your electric system and so will inscects so do it the very best you can. Even if it is just extension cords, still stick those suckers in a pipe!![]()
