[quote="Sparkydelux"]Hi,
I would like to know if it is permissible to wire a radial 20W downlighter circuit via a junction box.
BUT,The junction box is located at the centre of the run therefore my question is, could I wire up the lighting circuit so that it comes out of the JB and goes different ways (still being switched by the switch) or do I have to run it so that I loop around as one continuous radial?
Please could you advise as I have a feeling it may not be allowed due to radial testing. i would really be grateful if you could provide me with personal experince information.

YOU INTEND TO FROM THAT JUNCTION BOX EXTEND A LIGHTING CABLE TO FEED A DOWN LIGHTER.
YOU WOULD BE ALTERING THE CIRCUIT TO A CERTAIN DEGREE , AND
AT THE POSTION OF YOUR NEW LIGHT , TEST READINGS LIKE EARTH LOOP IMPEADANCE WILL BE A NEW QUANTITY AT THIS NEW POSTION.
LOOP IMPEADANCE READINDS DEFINE IF PROTECTIVE DEVICE WILL OPERATE ( YOUR LIGHTING CIRCUIT MCB / FUSE ) UNDER FAULT CONDITIONS .
IT IS FOR THIS REASON WHY IT WOULD BE ADVISABLE TO GET IN YOUR
LOCAL REGISTERED ELECTRCIAN TO TEST INSPECT AND CERTIFY.
