Christ you guys remind me of that guy that flew in to teach grounding and bounding a while back. Dude was supposedly some subject matter expert who worked on nuclear plants. Class was full of electrical engineers and electronic technicians. People designing circuits and tracing signals as their day to day. Course was just a check in the box type deal but we were all looking forward to have some of the strange current behaviors explained. Hell, the whole charade turned into who could ask why the most basic shit happened and he couldn't explain the why of anything. "We just do this and it works" was his go to answer whenever someone asked the why and how of things. Grounding loops were completely baffling to him but he knew they were bad and to be avoided.
Grounding is stupid important for my job, ridiculously over the top, but whatever. My last cert we used an engineering firm that audited primarily as a consultant and taught on the side. Pretty nice to have a real SME on it.
It’s like federal law though, no way you keep within compliance. I know enough I could walk into most systems and it’s not hard to find 100 minor infractions. Honestly even major ones are pretty easy to find.
Shit, today alone I probably broke at least 5 cardinal rules but at the end of the day I was inside a giant fucking concrete bunker in the city. Going to take a giant colossal potential difference where I was at to cause a problem or worry about any type of AC surge.
Have one data center where every fucking conductive data cable has to be shielded. I could probably pull any random cable and decertify 25% for testing as open. I had less trouble in big military facilities to be honest.
