- ars 16y agoThen you get grounding loops - not a good idea. Connect all the drawers to a single ground, using only one direction (star, not ring).
- oiuytgfrgh 16y agoGround loops probably aren't a big problem for a SMPSU - if you are putting power into a metal box you need to have a ground to the metal box.
