EFLI ?

[sybergav]

Hi all.
just about EFLI testing.
as3000 table 8.2
As it is titled- EFLI of total circuit
Is it my understanding that if I use the table for testing EFLI for a sub circuit say a 10a circuit I can test and check the reading. Then I can also test the sub main and again use the same chart or would you not test sub main just sub circuit ???

The clue is in the E external

The clue is in the E external

It means Earth Fault Loop Impedance not External.

Depends on why or what you are testing. EFLI is checked for all circuits whether it be sub circuit or sub main. For example the sub main to a dist board would have an EFLI and sub circuits from the board would each have an EFLI. The values are then checked against the relevant Table, that is how we do it in the UK.
