Hi Guys
Any advice/ pointers would be appreciated
Have âpretty bigâ new build house weâre wiring from scratch.
New supply in from DNO is PME, but we have Ze of 0.51
Are DNO obliged to keep this under 0.35?
Wouldnât be that much of an issue normally if regular size house and meter was attached to house.
Before we came along on the scene Client had separate garage block built, meter permanently sited in here.
Weâve run a SWA sub-main across to house DB 25metres away, but struggling on suitable overcurrent protection. Even at 80amps BS 88âŚ. Max EFLI 0.40!
Donât really want to be putting new build on TT system, if it comes to it.
Thank you
Sy
