RCD on a TT system

[salem2000]

As i said earlier, my system was a TT supply, splitload CU, 30mA RCD to all except heating & lighting, main isolator was 80A 100mA RCD.

This was later changed to PME Supply as earth rod missing/damaged, 100mA RCD still in place and have had no problems. Total cost to convert to PME £0 (EDF Energy)

When replacing the main switch on the CU with a Main RCD, you should put the original main switch into a two slot din-rail box, between the meter and the main CU, that way you won't need to pull the service fuse in the future, if the need arises to work on the CU etc.

Very good point Kai.
