I have a few questions concerning the EICR

[electricshock]

1. What do I put in the cpc size on the test schedule if the steel trunking and conduit is used as cpc?

2. same as above but for swa strands used as cpc?

3. how do I do zs at a 3 phase circuit with no neutral. My meter usually needs neutral to get zs measurment? (Unitest Telaris 0100 plus)

The NIC have a few accepted abbreviations for containment used as cpc..... 1. Trun, 2. Con, 3. SWA & 4. MICC.

Generally these should suffice regardless of what flavour of test form you use.

If you're sure your meter cant directly measure Zs, you can calculate if from Ze+(R1+R2).

I've never used the meter but can't you do a PSCC (Ri for that meter I think?) but connect L to Line and N to cpc?
The instrument shouldn't care that it is measuring Line to earth loop instead of the expected Line to neutral.

Like I say, I don't know your instrument so take this with a pinch of salt..........

RCDs will not like it of course if you have them!

Amtech does mine for me drop down has trunking then a wee box asking size hey presto actual size in the cert
same for SWA,conduit altho not light gauge/heavy gauge conduit
