I've replaced an overhead supply to a shed with a buried SWA cable. The
shed has an earth spike so grounding the SWA at the (PME) head end is
only to protect the cable - where can I find a spec for the size of the
grounding wire that connects the SWA shield to the main earth?

Thanks for all the responses - now sorted.
