Does anyone know anything about the old ELCB (or is it ELCD??) units, they were the fore runners to RCD's i believe.
I'm about to replace a consumer unit which is running on a TT earthing system (which at present doesn't have any earth!) and i wondered if i could use the existing ELCB in place of a 100A 100ma RCD as the main isolater?
My plan was to use a 100A 100mA isolater feeding the CU then use a split load board with a 30mA to protect the sockets etc. I'm a little reluctant to use a 30mA as the main incomer as it'll be a nightmare for nuisance trips.
Thanks
