Finishing off a refurb today and had one of those unexpected results (well for me that is)
All circuits have nice low R1+R2, IR's are all high as you would expect
Check Ze and get 0.11ohms
First RCBO 16A R1+R2 was 0.18ohms and Zs of 0.28ohms so as expected
Next RCBO 6A R1+R2 was 1.07ohms with Zs of 1.15ohms (did not check both 2way position yet)
Get to the first RCD circuit bank, Ring 32A R2+R1 0.21ohms, and Zs of 1.56ohms - er ?:|
so pick a circuit on the 2nd RCD bank Ring 32A R1+R2 0.23ohms and Zs of 1.68ohms -
So picked another at random, and similar result X(
As it was getting late and the house is unoccupied, decided not to headbang but retest each circuit tomorrow
Am I correct that a Zs reading from meters are calculated?, I know that I can add Ze to R1+R2 to get Zs, but can't say I've ever had this before, am I being daft, what have I overlooked?
The board is a contactum, have one here at home without issue, so this has thrown me a bit
