I am about to start wiring up a control box using the Auber Inst. enlosure sold on their web site and I have a quick question in regards to ground wires. On most diagrams I see on this forum everything is going to terminal blocks. However, the enclosure I am using is metal, so should I run the green grounds to a bolt and attach it to/thru the metal enclosure? Of course this seems like a no brainer but I am in no way an expert and just wanted to check.
