Still no guarantee the RCD would trip.

Best option not to put nails through the cable then. 
Indeed, but the theory (hope) is that it would 'if it needed to' - i.e. if there were a path to earth through the person which resuted in at least 30mA flowing!
Kind Regards, John
That's because he didn't do enough studying in advance.

I agree with BAS on this occasion - you should be sure of how to do what you are doing before you start. If you are unsure once you have started you should stop, go and find out the information you need, then commence work in a safe way.
The OP says he didn't energise the circuit before asking for advice here, but only after the error of his ways was pointed out.
People often seem to treat electricity in a different way to other types of work - very few would consider removing a chimney without advice before proceeding, or repairing a gas boiler. But with electricity there is a worrying trend of trying it out, and if it works it must be fine.

It was not I who wrote this:
So your objections to being reproached should be directed at phatboy, surely?
So saying that I'd prefer it if people learned about things beforehand, and acquired a full and genuine understanding of how it worked and exactly what to do before they picked up a screwdriver was exerting my superiority and denigrating you, was it?It seems while a lot of decent folk are on this forum who are willing to assist and help, a certain few are more interested in using it as a platform to exert their superiority over a subject and denigrate others.
Out of curiosity, why don't many of the appliances that we plug in at 13A sockets not contain an earth in their leads?
Because the appliances are double-insulated so they don't need one and
the flex is not 'fixed wiring' as are the cables being discussed in the thread to which the regulations apply.
It would be 'safer' if they did especially for outdoor equipment and tools.
I suspect big business economics may be involved. Safety is one thing but ...

Okay. So next one
Why don't many 240v downlighters contain a terminal for terminating an earth? They will always be part of a fixed wiring set up - it's the lack of terminal that led me to believe that one should not run an earth to them.

Cheapness.
All the ones I have fitted had an earth terminal..... are you using cheap Chinese imports similar?
Aurora are a decent brand!
The reason that fitting doesn't need an earth is that its' Class II, the instructions and presumably the actual fitting, have a terminal to terminate the cpc, even though it's not required by the fitting.
If it was a truly cheap & nasty fitting it would just have two terminals and you'd have to decide what to do with the earth yourself.

Oops. Confess I was mixing up the 240v & 12v downlighters. The 240v do have earths (and are wired 3 core flex) & it's the 12v that don't and are wired with 2 core flex.
from the transformer to the fitting, yes, as the secondary side of the transformer is SELV and doesn't require an earth, no matter what the fitting
