Refitting bathroom on a late 50's property that I have recently moved into. I understand the need to have an RCD protected lighting circuit, however my current install which has a modern CU seems to have retained the old metal conduit for the lighting circuit up and downstairs, and is currently wired to the main switch side of the CU and therefore not RCD protected.
Difficult to see whether all the wiring was replaced when the CU was fitted, but it probably wasn't! All light fittings still have the circular steel mounting boxes sunk into the walls. The ring main is T&E but sheathed in the old solid green not green/yellow.
As I am laying a new tiled bathroom floor I will not be taking it up in the future if a re-wire is necessary. I was thinking I could lay the wire in preparation for connection at a later date, and placing any junction boxes outside of the bathroom (i.e. under the landing floorboards or the adjacent bedroom). The rest of the house is to be decorated anyway so I can put new switch boxes in place /run next to existing ones.
There are two spare slots on the 30mA RCD part of the CU which I can use for lights up and lights down.
Until the new wiring is in place and connected is it acceptable to move the current lighting from the Main side of the CU to the RCD side whilst maintaining the current earthing on the conduit?
Or should I just cross-bond in the bathroom as an interim measure until all the wiring is complete?
