replacing a light fitting

[pistonbroke1957]

Want to replace a light fitting which is wired up as the picture.
The new fitting fits flush to the ceiling so I have to
remove these connections and only has single L,N and E terminals.
I know very little about electrics,so I don't understand why 1 of the
3 black wires,which I assumed were neutrals,is connected to the live side.
Do I connect the 3 red and 1 black to the single live terminal of the new fitting
and the 2 black to the neutral ?
The light has only 1 switch
Thanks

If you wanted your light to stay on constantly that's what you'd do.

Have a look in the Wiki. //www.diynot.com/wiki/Electrics:Lighting-Rose

Even knowing very little about electrics, I don't understand why simple common sense doesn't tell you that if you connect something up differently to how it's connected now, it must then work differently to how it works now...

Thanks for the reply lgiffer.

Looks straightforward enough from the diagram.

Neutral is the name given to the conductor which completes the circuit from the load back to the supply.

It is not a name for black (or blue) wires.

Wires can be anything we want; they do not know what colour they are.

It should really have a sleeve of brown on it indicating that it is the switched live coming back from the light switch plate, you'll want to invest in some earth sleeving while you're at it too...

Why?

It's better to use red, but you know what he means. The switched live should be marked accordingly.

Why?

Why not?

What does a bit of red or brown sleeving on a conductor tell you?

 

[Taylortwocities]

We did this to death some time ago.Did you want to do it again?

From my practical POV it tells you that the conductor is live or may become live. It also helps on forums, like this, where not-so-experienced-as-you people start to wire up their IKEA light fittings and are faced with three black, or blue, conductors to deal with.

Something in 514 says conductors shall be identified by colour in accordance with Table 51. And table 51 says a line conductor shall have the brown colour.

 

[ban-all-sheds]

I don't disagree with any of that.

For some reason I thought that the suggestion was to sleeve a red/brown conductor.

IHNI what that reason was.

 

[Taylortwocities]

Aah. Me neither!

Quick - frame that post!

Ban admitting he was wrong....
