After reading this thread, I'm questioning the propriety of using aluminum subpanels with steel DIN rails and clip-on grounding terminal blocks.
I'm assuming if all grounding terminal blocks are bonded together with a wire, eliminating dependence on steel-to-aluminum connections to the subpanel as a grounding backplane, the grounding issue should be mitigated.
Am I correct in this assumption, and also can you think of other issues or problems associated with an aluminum subpanel that would be mitigated by using mild steel?
I was favoring aluminum because it's lighter and thicker, and thus is conducive to drilling and tapping for component placement.
Thanks for any insight.
