8 metre meter tails

Hello All,

Scenario is; conversion of basement with a 3P supply to 3 separate flats. TNCS. To get a new CU into the furthest flat I've proposed 25mm singles in Scottish Power red conduit. The conduit would be run in the correct zone in a void about 100mm above a plasterboard ceiling with no insulation at this point. I get the max current to 80A for this method and a fused switch would be installed at the origin after the DNO cut out Have I missed anything here? I'd assume to measure volt drop to the origin and disconnection times to the CU as per.

Thanks for your time,

Pete

Hi Andy,

Yes, I confused the issue with 'meter tails' but it's certainly the (TBC 25mm) line,neutral & CPC between the switched fuse,/8 metres/CU.

I'd anticipated running up in conduit on the outside of the wall in the cupboard into the ceiling void and continuing in conduit the 8 metres run through to the next flat. Staying in conduit on ext. of wall there straight to the new CU.

Scottish Power Red not a regular SI unit I know...its a 5mm wall I think and yes PVC,

Thanks,

Peter
