Been called to a job for a second opinion,
Previous spark said current db set up would warrant a code 2 and therefore need a board change.
Granted the elcb set up isn't great for discrimination but cant see this warranting more than a C3.
But what about the elcb itself?
It Tests out fine.
Any written confirmation that elcbs aren't compliant?

Yes it is actually an rcd just realised, first spark must be after a Payday.

came across a couple of these MEM RCDs. they totally ballsed up Zs readings. one was even to the extent of adding 349 ohms to the value.
