[QUOTE="ElectekAir, post: 15614, member: 937"] Recently changed a consumer unit on a TT system, old RCD black with yellow test button (you guys know the one) installed a new earth rod and a new 17th consumer unit. Everything ok, INS resistance ok, Ra good. RCD tripping at first both of them, removed 1 RCD to make it easier everything removed from system and re-tested only low ins resistance reading is immersion 2578 ohms now if you plug anything in and turn it on i.e. fridge, kettle ect it trips RCD removed as it is an occupied property and they need power. Any suggestions? [/QUOTE]
