Regarding voltage ELCB's BS842 I am currently looking at replacing an old Wylex fuse board with a new C.U with individual rcbo's system is TT. Question is if I remove the earth connections from this device can it be used as the isolator switch for the new CU?

    Then leaving the old ELCB as a main isolator can be considered acceptable, though a tadge scruffy.


    There's things to consider regards earth fault protection between the tails, main switch, busbars and the metal enclosure of the CU, replacing the ELCB with a suitable RCD in a plastic enclosure has a lot of merit or a suitable double pole RCD as the main switch within the consumer unit..
