am I wrong or am I right

Gonna make this short and sweet guys

3 phase supply into building each phase feeds a bank of 60 amp 1361 fuses. Each 1361 fuse feeds individual domestic property's, now on the eicr it asks for number and type of live conductors. My opinion is I would put 3 phase 4 wire, but another spark is disagreeing with me, because wer testing the single phase supply in the domestic property which is single phase so he thinks its 1 phase 2 wire

if your testing the single phase then it is 1 phase 2 wire. surely the electrical supplier is responsible for testing their work

 

[Darkwood]

When noting the type of supply etc TNCS, TNS etc you also enter the nature of the supply 3ph...4wire etc because that is the question it asks, you testing and results and other info throughout you report will be clear that only single phase of this supply is been used .... you could always put it as a note.... that its a shared cutout.

i would record the details of the supply at the origin , which is 3ph / 4 wire.
just because its 230v downstream doesnt change the characteristics at source.
so youre right , colleague = plonker ;-)

 

[m1ck_b87]

Totally agree with last two answers

 

[m1ck_b87]

Does that makes evanjjrraves a plonker 2

 

[Guest55]

never heard of him.

 

[evansjrraves]

think I mis-read the question, that makes me a plonker

Never mind Rodney... opinions are better received wit relevant references to support them but best to ensure you read the OP correctly to start with saves the red face

 

[sparkymalarky]

3 Phase 4 Wire. Couldn't be clearer.

What installation RU testing the TPN or SPN asimple really

 

[thomas-1981]

The EICR and schedule of results will be for the DB in the Domestic property. So the supply you note on the EICR is for the Domestic DB not the building as a whole.

 

[m1ck_b87]

Disagree Tom as so one put previous the characteristics at the origin don't change it is a 3 phase incomer

 

[chrish_1977]

Sub main, just done one today, 3 phase incomer and split over 7 flats, switch fuse isolator for each flat in mains cupboard and tails straight to each board, top line on schedule of test results for when the consumer unit is not connected directly to main incomer

Its just been posted and il re-iterate from my earlier post ---CHARACTERISTICS OF THE SUPPLY AT THE ORIGIN...... it couldn't be much clearer... regardless if it a 3ph incomer with 2 phases unused its still noted for what it isregardless of what part of it your board is connected toand as ive already said although its not required you can always right a comment regarding that its a shared supply, or blanked of on 2 phases etc.
