Question:
What is supplementary equipotential Bonding (Supplementary Bonding)?
Wrong Answer:
Supplementary Equipotential Bonding is connecting together conductive parts of an electrical item and non-electrical item such as an electrical shower unit and the copper pipe work of the bath in order to prevent the occurance of a dangerous voltage between them under an earth fault connection.
"conductive parts of an electrical item"? - What,
all of them? Would that be safe?
"non-electrical item such as ...the copper pipe work of the bath". Even if the pipes are not extraneous-conductive-parts? Would that be safe?
Height of sockets, switches & controls
"The building regs require that all switches and socket-outlets be installed so that all persons including those whose reach is limited can easily use them. Sockets-outlets and switches should therefore be installed at a height of between 450mm and 1200mm from the finished floor level."
Wrong.

Go away, you pointless and incompetent waste of space. The OP isn't still waiting for an answer after over 3 years anyway.
