Evening gents, just seeking a little advice. Recently bought a new place, it has mostly been rewired, its on a TN-CS system. The garage which is approx a 40m run from the house is supplied by a 2.5mm cable believe it or not, it is donkeys years old. This supplies a 2 way rcd board in the garage, the wiring in the garage is all new T&E, which supplies a few lights and socket outlet.
Going to run a new 10mm SWA 3core armoured from the board, some of which will be clipped to a fence and some burried. Going to put this on a 40amp RCBO. With regards to the earthing arrangement in the garage, would it be sufficient to use the earth from the MET, or do you think it would be better to have it off an earth rod. Just thinking distance wise, might be better off with the second option. Thanks in advance. I am a qualified electrician, just have a been out the game for a couple of years.
