What size wire and hole? You can get pin crimp lugs for larger cables.

It's about 2.5mm hole and 6mm cable.
thanks

Didn’t realise you only needed small ones. You can get those from any wholesalers. RS do tend to offer an overnight service.

I have found I am needing to use ferules more and more to downsize cables to ensure the fit in fittings. Unless its a PDL 32A hob switch, others struggle to get two 4mm into the screw holes. Most domestic light fittings have choco blocks which only take a 1.5mm cable, trying to jam two 1.5mm for looping is a nightmare.

Not to mention all the double insulated fittings with no provision for an earth or room to fit a loop terminal, or downlights without room to terminate the sheath inside them.

OP: I havent come across that situation before (except for perhaps on old 1940s neutral bar). You could add another bar to it with a bolt and double nut connection.

A nicely stripped 6 mm wire (not twisted) will surprisingly fit into a lot of tight holes.
