just been told that installing a ringmain to the 17th that at the db/cu the cpc's have to go in seperate terminals on the earth bar?also if you ran two radials along two walls it would be good practice to link the last two outlets with a conduit containing a earth wire connecting to the earth on each radial.
the first item i've done before on rings for IT rooms but the second ???
