That's even deeper, and is typically about as thick as your arm and a
real pig to make connections to.

Surely a cable to a house is not that thick? The house supply is about
half an inch diameter.

A very small house ?
You're probably looking at at least 16mm^2 SWA which is about 20.4mm
diameter for 2 core; 25mm^2 is about 24.1mm OD. The 100A supply to my
house is about an inch over the armour.
