@ian.settle1 , That YouTube clip took me on a right ‘rabbit down the hole’ trip - YouTube is fascinating and so time wasting!

Do quite like JW though...

Of course, if you have multiple cables, as long as you don't put them through a single hole...just don't put them through any hole at all...and everything will be fine...so my wife tells me...

I watched the video and a 110Amp current through a 25mm conductor gave a temperature rise of 2 degrees celsius above ambient. I guess over several years this might add a few quid to the electricity bill but it's not going to be any kind of significant fire hazard or safety issue.
