I have a ccu with a Ze of 0.09 and it's supplying another ccu which that board supplies multiple other CCUs I was wondering how I would work out my zs and ze on the other boards?

Does it not become Zs at DB? from board to board, I hear what you're saying, but does my statement not hold water in this case?Ze is only at the origin, the rest are Zs.
Measure/calculate the R1+R2 for each distribution circuit and add the Ze. (Zs=Ze+(R1+R2))

Each board would have its own Zs, sometimes referred to a Zdb. I think we're saying the same thing.Does it not become Zs at DB? from board to board, I hear what you're saying, but does my statement not hold water in this case?
Yes exactly nice one MateEach board would have its own Zs, sometimes referred to a Zdb. I think we're saying the same thing.
But, 'Zs at DB1, 2, 3', whatever, is a statement...nothing wrong with the terminology, whatsoever.Yes it does become the Zs at the DB, but obviously that is also the Zs of the distribution circuit because they are one and the same thing.
Strictly speaking 'Zs at DB' or 'Zdb' are not correct terminology, much like 'ring main' instead of 'ring final circuit', everyone knows what is meant by it, it's commonly used, but it's not correct terminology.
