Hi all. I am planning to build a shelf layout approximately 25'x13'. I want to run one loop around the room. Shelving will be approximately 18" down from the ceiling. I am not putting crown moulding under the shelving. So what advise can I get on laying the main bus wiring for the track to where it will not be seen? I have viewed many shelf layouts on Youtube and Googled shelf layouts and there is virtually no talk of the best way to wire it. Any help would be greatly appreciated.
