Hello folks, I'm new on here so bear with me lol. I have recently returned to the electrical contracting industry after a four year break.
On my return I find that I am working to 17th edition rather than 16th which I was used to !.
In 2005 I was involved in so many LHA contracts where I had to upgrade outdated earthing systems and install supplementary bonding in bathrooms. Virtually everything in the bathroom received a supplementary earth !.
Now that has all changed and in most cases, supplementary bonding is not required provided RCD protection is in place and the incoming services are correctly bonded with 10mm MEBC's.
I cannot get it out of my head that RCD's can fail. I have done enough inspection and testing to see that this can happen. Is it right to rely so heavily on RCD's to protect people against electric shock ?. Surely it would be better to have both supplementary bonding AND RCD protection (EEBADS) as protection against electric shock rather than just RCD's (ADS) (given the MEBC's are still fitted).
Do you agree with ADS ? or do you prefer EEBADS ?
Best Regards
Tim
