Good Good!

So on EIC..

I put in the "External Earth Fault Loop Impedance Ze" = 0.20
& For my "Prospective Fault Current" from my readings what would you put in the "kA" Box ???

Yep and the PFC box you put your highest value of PEFC or PSCC which is 1.01.

Odd though as normally on a TNCS they are near enough the same, but dont worry about that for now!

So from my readings you'd put in "1 kA"

and the maximum this can be is 16.5kA, Is this correct?... and this will be written in the "Short Circuit Capacity" Box on the EIC?

Ok Nature of Supply etc.

External EFLI Ze is the max so for TNCS its .35 There is then a box underneath for Measured Ze

PFC Single phase is what you measure so 1.01kA

Short Circuit Capacity is normaly 33kA for BS 1361 Type II 100A fuse.
