Living light fitted - Now bedroom light doesn't work

[Roy O]

Hi, I've just installed a new light in the living room. The make is a Nud light.

It has no earth so put the earth in a choc bloc.

There are 2 black wires and 1 red. I wired 1 black (neutral) wire to the fitting, and 1 to the choc bloc.

The light works, but the bedroom light no longer does.

Please could you advise on what to do? Do I need to pigtail the blacks and use a wire nut?

Very very new to this so any advice appreciated greatly

Cheers

Roy

How were they connected together before?

Sounds like you need to connect both blacks together into the light fitting, but I can't say that for certain.

You have connected a (non used) building Earth wire to an isolated terminal on a "choc bloc".
You have also connected a previously used building Black (Neutral) wire to another isolated terminal on a "choc bloc".

It is probable that the now isolated Black (Neutral) wire is the Neutral wire for the bedroom light. Connect it to the other Black wire.

Plan B, of course, is to accept that trying to work with lethal voltages by trial-and-error, connecting things together in different ways, hoping to luck onto the combination which works, is pretty high on the scale of 1 to stupid.

Roy - now that you have decided not to replicate the way the wires were connected in the old light, you need to get a proper 2-pole voltage tester or multimeter, and positively identify them so that you can put them in the right places in the new light.

I wired 1 black (neutral) wire to the fitting,

How do you know that it's a neutral?

Do I need to pigtail the blacks and use a wire nut?

Were the two black connected together in the old light?

Do I need to pigtail the blacks and use a wire nut?

That terminology is not used in the UK. Neither are wire nuts.

 

[ban-all-sheds]

Well you can buy wire nuts here....

 

[securespark]

Bits of yankie rubbish.

 

[ban-all-sheds]

Well, yeah but...

I removed a wirenut recently. Can’t for the life that of me remember where but it was still doing it’s job long after the guy that put it in will have been. Still, ‘orrible things

Can't understand why the new fitting can't accept two neutrals.
Can't understand how you selected which neutral to go to the light fitting, and which one to put in a 'choc bloc'.
Can't understand why you are talking about 'wire nuts' when it seems you have 'choc blocs', one of which could be used again, only correctly.

Singles, line looped at the switch, neutrals looped at the rose.
Normally with manky old slip conduit and rubber insulated wires from half a century ago.
Although not impossible that it's a more recent installation, or is proper conduit, or both.

 

[333rocky333]

ah singles thanks.
I did wonder why BAS was later refering to the blacks as Neutrals

 

[ban-all-sheds]

You know, try as I may, I really can't see how this:

I wired 1 black (neutral) wire to the fitting

How do you know that it's a neutral?

qualifies as "referring to the blacks as Neutrals".....
