Hi all I wondered if someone could please help
Doing some new builds with a substation about 30 yards from these two houses I'm currently on.
Initial testing I had a normal PFC, I don't know why but now the readings have changed (they have connected in a lot more houses on the site since ).
My ze is now around 0.03 and PFC around 8ka which is above my rcbo ka value of 6ka.
Not really come across this before, am I still ok where it has a 16ka 1361 protecting the house or is there something else I need to do ?
Thank you
