Some basic rules for the installation of cables to protect them from damage
Cables in a wall or partition
A cable concealed in a wall or partition must
a) be at least 50mm from the surface [note 1]
b) have earthed armouring or an earthed metal sheath (eg SWA, a BS 8436 cable or MICC cable)
c) be enclosed in earthed steel conduit or trunking
d) be provided with mechanical protection (3mm steel is deemed sufficient to meet this requirement)
OR
e) be installed in a safe zone and have 30mA RCD protection.
Note 1 - If the wall or partition is made from or partially made from metal than the cable will require RCD protection
