Hi Sparkwright, thanks for that. At least there's someone on here who has common sense! A few questions:
Why must the ceiling wiring be re-routed to a new position?
When I run the TE to the first junction box, can you tell me exactly what junction box I need? I assume the TE goes in one end of the box and terminates in a bloc inside the junction box, but the TE 'continues' to the next junction box via another length of TE?
Meanwhile, the fly leads from the lamp also connect into the same junction box? Do the fly leads need to be any way around? Is one live and one neutral?
