[QUOTE="SPECIAL LOCATION, post: 42866, member: 250"] 1667 -vs- 1666 is actually 1666.66667 recurring. (50v / 30ma) I have NEVER been told to do that? ?:| :| passed my 17th 11April 2008! well had my NIC annual inspection 2nd week of Feb... checked two jobs.. Both full rewires... Both full RCD/RCBO 17th ed compliant CU's.. All my EIC certs had the max Z's values from table 41.3 written in them..... no comments were made about either? :| I still tend to er on the side of caution... what if your RCD don't work? be nice to know the MCB has best possible chance of doing the business with a live-earth fault?
