Replacing light fitting

[leanneb]

Looking to replace currect standard light fitting to new crome one. Remove the celing rose to find 3 browns, 3 blues and two earths.
New light fitting has chocolate box with 1 blue, 1 brown, 1 earth. Which wires to i connect to this and how.

Have you taken down the old fitting yet? If not make a detailed note of what wire went where. If you have taken it down do any of the blue cores have a brown sleeve/tape? If so, this connects to the brown in the choc block. if not you will need a multimeter to find the switch wire.

After you have determined the switch wire, you need to connect all the reds together in a separate terminal block. All the earth conductors to the earth terminal and the 2 remaining blue conductors to the N terminal.

Haven't taken it down, best not too just yet! I know which one is the switch wire, so I shall connect this to the brown on the new fitting.
When you say connect all the reds together in a terminal block, these won't actually be used then? I just push these up into the fitting? And I'm sure my wires were brown, although they may well be red - was a bit dark!
Thanks for your help.

Yes sorry, I meant brown, not red.

The browns are the permanent lives, and the 3 cores are the input live, the live to the switch, and a live to the next fitting. These need to be connected together but are not actually used for the light fitting.

Substitute red for brown, and black for blue
