Not always readily available in my experience and I have a keen interest in open PEN faults.Here is a statistic I got last night in a newsletter from my regulatory body which may be of interest.Electrical fatalies have steadily decreased since 2000.There have been no fatalities in last 3 years. This same period corresponds with the implementation of TNC-S nationwide.Are there any statistics with regard to the occurance of open PEN faults
Open PEN faults did,nt exist in the early 1990,s because we were TT.Now we are no longer allowed to use TT.Surprised by these statistics? I was. It does undermine my "crusade" against TNC-S but I,m happy to be proved wrong if the stats show that I,m wrong
A valid point.But as pc1966 says ,it's a less serious situation than an open PEN and in reality the loss of the suppliers earth or indeed the loss of a circuit CPC will usually manifest itself either in a telltale "tittle" at bonded or exposed metalwork as soon as an appliance with intentional leakage built in is plugged in to a socketAs a aside it begs the question why we don't have devices to check for the loss of the suppliers earth on TN-S supplies which I have found more often than an open PEN
