I thought this little tip might be useful.
I have been installing two-way switching to the upstairs passage lights.
I needed a junction box that would accommodate these eight cables:-
Earth
Live in
Neutral in
Live out to next light
Neutral out to next light
Switched live out to passage light 1
Neutral out to passage light 1
Switched live out to passage light 2
Neutral out to passage light 2
Brown to intermediate switch
Blue to intermediate switch
Brown from intermediate switch
Blue from intermediate switch
Red to two way switch 1
Yellow from two way switch 1
Blue from two way switch 1
Red from two way switch 2
Yellow to two way switch 22
Blue to two way switch 2
i.e. seven different terminals.
So I rummaged around and found an old plastic surface-mounting box, and into this I put a 7-bar "chocolate block" connector. The knock-outs were easy enough to do, and then a new blank cover plate finished the job off neatly.
The only extra cost was the cover plate. Sorted!
And I did the same when I wanted to extend a ring main. I cut the ring main, and then installed a 5-way connector into another (deeper) old plastic surface-mounting box :-
1 Earth
2 Existing Live In
New Live Out
3 Existing Neutral In
New Neutral Out
4 New Live In
Existing Live Out
5 New Neutral In
Existing Neutral Out
Just one point, though - is it acceptable to have just the one earth connector? Or should there be two, to maintain the "ring effect"?
