Just tested an RCD that passes x0.5 (no trip), x1 (23.5ms) 0 degrees x5 (4.4ms) but fails 180 degrees x 5 (Touch voltage >50v - error 4).
Zs at the socket where I measured is 0.39ohms.
Meter is Fluke 1651 - but using the plug and not the dreaded croc clips! Passes the other RCD in the 17th edition board.
Any ideas? Can't think how an RCD could be so selective on what it fails!
Will replace RCD soon!
