Stefek,

Thanks for the reply.

Remember to leave the JB nominally "accessible"...

Though I know this is recommended (and I will do it) I do wonder exactly
why. Apart from a total rewiring job, the only reason I can think of for
ever needing to get to the junction box again would be if the terminals
needed to be re-tightened. Is this likely? And in any case, how would I
know that it needed to be done? Are there recognisable symptoms?
