Earth continuity

I thought his reading was based on the end-to-end resistances, which wouldn't be affected by the socket contacts. Presumably the actual terminal screws are tight in the socket outlet.

End to end resistances wouldn't be affected by the socket contacts, am I missing something?

Ah right I've got you now, you mean the actual contacts and not the terminal screws, will pay more attention next time!

If the building has block work and the sockets have a fly lead it is possible that you are getting parallel path via the building?
