So, how then would one know that ALL member states have implemented these directives? Would it be officially announced (OJ?) or are the 2016 dates the drop dead dates for the member states? And, will ETSI finish it's revision process of it's RED standards by then? Just curious on this

The 'star' washer should be gas-tight seal. If a serrated-headed screw is even less of seal, than higher risk-level indicated. Faulty logic? Anyone else observe failure modes of ground-bond hardware? The CSA Design Manuals (not all standards have a respective D.M.) have drawings and

I had an application where the tab used for bonding the sheet metal cover was spot welded to the cover. Inside were conductors protected at 125A. I was wondering how many spot welds might be needed to ensure that a ground fault wouldn't simply blow the spots off before tripping the breaker.
