Hi all I passed my 2391 about 6months ago and thought I was flying, I know test procedures & how to carry out the tests like the back of my hand and I fully understand any results I get and how to rectify or diagnose any faults in a electrical system.....but then again I have only tested ddomestic installations.
We have recently been doing some wiring on a site, 55 flats & 3 shops below, we're would you even start on this!? (I am not testing it by the way before anyone jumps on me) it's been tested a few weeks back but was so busy on there I couldn't get to put my eyes over what they did.
The apartments had a 10mm swa from the plant to each flat, so I understand Would have to take a ZDB for the swa ze + (r1+r2) of swa
the apartments are a doddle
were would the Zdb reading be noted? Would the supply cable be noted on the schedule of results for the appropriate apartment but marked as a supply cable instead of a final?
Or would it be marked down on the test sheet for the plant room, again what tests would be carried out in the plant room with all the kwh meters, the 125mm armour coming in would they take a Ze from this? How would the pfc work, would you go from all three phases and record highest?
I really don't have the knowledge or experience I thought from the 2391 and this was certainly not covered!
Cheers guys
