Evening '

I have to joint 6 twin and earth lighting cables in a loft for a kitchen below , switch lives etc .....

The wago boxes I use are not big enough '

I was thinking of using a 4 x 4 plastic adaptable box with stuffing glands '

With all my wages inside

Any body see a problem with this method it will look like a rats nest in box but connect ions will be sound

Thanks

As you say, it will be a mess to look at, but there is nothing wrong with doing it like that.

Dont see a problem with your idea, however it will only look like a rats nest if you leave it like that
Spend a bit of time and dress the conductors, start with the earths and work in a logical manner

What size twin and earths? I reckon you will get them in a wago box unless they're 2.5 or bigger.

Otherwise, nothing wrong with what you suggest, I tend to use the little round whiska boxes.

If it will be accessible in the loft, ie not boarded over it might be better to use connector strip inside your adaptable box. Also I wouldn't bother with the stuffing glands, just drill the box as necessary, screw the box down somewhere and clip the cables where they leave the box, just as you would with a normal JB.
Of course if it won't be accessible then Wago's or Helacons are the answer,

Sounds like a great idea, I will look forward to finding this junction in the future! £££

Cant you use standard 20A click junction box's? Bit more robust I think.

If you do use a plastic JB NAPIT use to tell me the connections could not be floating in the box they had to be fixed. I can't remember what brand, maybe Wiska, do a good 6" plastic JB with good size pre-fixed screw connections in the box and loads of room!

Whats wrong with floating connections in a box

If strain relief used on the cables entering & wagos used ?

Only flexible cables require strain relief, clip the cables just outside whatever box you decide to use.

It's 6 ligting cables - buy a dual socket patress and a dual blank plate

Thro' crimps, chock blocks or wago's to suit

Have you lot never done RB4 style lighting layouts before ?

I don't want to sound dumb, but what are 'RB4' lighting layouts?

It's a type of junction box. All feeds and switch lines terminated there so just one cable at each switch and fitting.

Still the best way to wire on some occasions i thnink with the amount of lights going into some places these days.

OK - have you come across the phrases "two plate and earth" and "three plate and earth" when talking about lighting circuits.

At the luminaire position (traditionally a ceiling rose) you would have either:

A two plate rose consisting of a switched live terminal and a neutral terminal and usually an earth terminal.

A three plate rose consisting of a switched live terminal and a neutral terminal and a permanant live loop-in terminal and usually an earth terminal.

From there, you should see that a 3 plate system wired in T&E has a live and neutral feed in, loop feed out and a switch feed and switchwire dropping to the switch

For the two plate method, either you loop the feeds at the switches (typically as a singles in conduit system) so the rose ony has a switch wire, neutral and earth or (if you are using T&E) then you locate a junction box and wire in T&E from that junction box so you have a switchwire, neutral and earh at the rose, a switch feed and switch wire at the switch and you make the relevant links from live feed to switch feed and connect through the switch wires at the junction box position.

Typically, that junction box was know as an "RB4" - which was the stock number of the manufacturer.

Over time, it got called an RB4 regardless of who made it - go back far enough and it was probably screwits in a 4oz tobacco tin or a version of that designed to accept lead sheathed cables.

It's basically a description of a joint box method used with two plate and earth luminaires

and now I do feel old !!

Try Here

Strip the ends of the cable cores, twist them together and screw one of those on to keep it all in place - they have a tapered internal thread cut in the ceramic to tighten the joint and stop the screwit falling off

I used to do those 'RB4' with 6 terminal JBs. which mean't that you could terminate 2-way lighting.

I prefer the use of an adaptable box with a connector strip. We used to call it 'Octopus wiring' and is very useful for terminating lots of cables at one location for kitchen/utility/outside areas in old cottages.

thanks for that, I can remember some of the older guys talking about "porcelain" type of connectors for low current terminations, would that be correct? I have never seen one.

That's the sort of thing they would have been talking about

You can still but a modern plastic verion with an internal brass thread - the americans still use them on a daily basis

I can't say I ever used them in anger - only during strip out to be honest - but like you, the older guys I was apprenticed to had used them
