You would have a zs on a sub main, and you would calculate it or measure it as normal.
 
Zs is carried out at the end of a cct

Ze is carried out at the board

Zdb is carried out at dis boards

HTH and no need to shout lol :D
 
Agreed, but it is generally called Zdb, you'd call it Zs on the test results for the board that is feeding the sub main.

Yep, agreed too as a submain is not a final circuit.

Seems we all agree, all Im saying is that a sub main has a Zs and not a Ze in reply to Wallyanker's post.
You can call it Zdb or Zebedee if you want, but it's still Zs.
