4293 elcb coding __________

[Judd]

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?

C3 but only for the fact that it's an up front RCD, so if it trips everything goes.

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

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.
