Posted By Topic: 2 core cables

Oct 08 2019 20:57

An old house with rewire-able porcelain fuse sw-board, 2C (without E wire) cables for lighting and 2c+ barred Earth TPS cables for power points.
The owner wants to upgrade to the standard current sw-board and upgrading all lights to LED down lights (which are class2 type without earth connection). Presuming all cables pass the IR test, please advise whether I have to rewire these lights with 2C+E new TPS cables or just pull an earth wire to each luminaire that required the earth.

Yes that's fine. You don't have to provide an earth at an existing lighting circuit if it is not required for the fitting.

Sleeving any bare earths at any fittings you work on as well.
