Mains cable


As you may have seen in other posts I am adding a spur socket to one of my existing ones.
I have one more question.
Is there a minimum depth that the cable needs to be traced into the wall?
TIA

Providing it goes vertically from the socket, no.

Either 50mm, or not at all.
Not at all only applies if the run is in a specially prescribed zone, which includes at the end of a wall, at the top of a wall (not bottom), or vertically from a visible electrical fitting. You can also run horizontally from one, but this is usually discouraged.
If you install at any other location, you need 50mm depth or mechanical protection.

If you look more closely at the regs this rule only applies if the cable is concealed in the wall and not being terminated in an outlet. ie. if there is no way of knowing that the cable is there. With an outlet present you know there is a cable running vertically or horizontally.(Or, you should be able to assume so). Again, if it runs diagonally it has to be 50mm or mechanically protected.
