This is a question further to my other thread "Help to check quote".
The house I may be going to rewire is ex-council.
The main board is at the bottom of the stair in the hall.
It is a metal cabinet about 250mm wide x 600mm high and 150mm deep built into the wall with a metal door and contains the meter, the Cut out fuse, Neutral block and a metal consumer unit fixed to the inside of the cabinet.
There is no earth terminal.
As far as I can see (without stripping anything down) the mains comes in in conduit and earthing is achieved by the conduit being connected by to the metal cabinet by a lock nut and gland and the consumer unit screwed to the
metal cabinet.
I thought the best way to earth it was to use an earth clamp onto the conduit just below the gland and connect to an earth block inside the unit.
Would there be any problems with this?
