I have just discovered that my house has no earth connection provided by the
electricity supply company. It has in effect an old sub mains pair of red
and black cotton/resin covered tails coming straight through the wall in the
cupboard under my stairs from next door in metal conduit. The main supply
head must be is located next door (the house next door is empty and I am
trying to trace the owner at present to gain access) which presumably has a
properly bonded earth connection point. The old red/black incoming supply
tails have a fairly modern grey main company fuse head on them but the
normal earth outlet (next to the neutral connection) has not been connected
and remains in its factory sealed/unopened state.
The electricity supply company has not provided me with an earth connection.
An electrician suggested I got access next door and ran a large earth wire
from their main earth connection through to mine. I will check what has
been done inside my consumer unit as I suspect the earth and neutral bus
bars may have been linked to provide protection.
What should I do as I intend to replace the old Wylex consumer units with a
modern 17th Edition RCD/MCB split box. I have no official earth point so
wonder what can of worms I may end up with. Is it OK to link Earth/Neutral
in my own consumer unit?
If the owner lets me in next door I can get their earth connection brought
through which is probably best. I understand that installing my own local
earth rod is not the best way forward.
