I am currently looking to install multiple outlets in the middle secton of a wall in one room and was wondering if any others have done this to prevent seeing any cords hanging from each machine? Also being new to the hobby I noticed that none of the transformers have a 3 wire plug that include a ground ciruit. Why is that? I wouldnt mind having them plugged into a ground fault protected socket but without a ground prong on the power cable it wouldnt be possible.
