1.0mm against 1.5mm T&E lighting circuit

[Aggravated]

Hi, to one and all, my first posting, as the title suggests, what do people think about the differences between the cables, I know that the circuits should be carefully designed and considered, insulation in lofts/walls, length of runs etc, but to my mind it should be 1.5mm. The cable manufacturers don't make single 1.0mm

Wonder how many will admit to being cheapskates.

You can apply a similar argument for always installing 25mm tails at the CU!! More often than not, 25mm is just not needed, and won't be needed for the foreseeable future and beyond.

No, but I'll happily admit to being lazy. I can't be bothered with buying/stocking two sizes for lighting, so all I stock/use is 1.5mm. It's not to say there's any issue with using 1.0mm, or that I wouldn't use it, simply that I don't.

I don't have an issue with terminating 1.5mm as some have said, if anything I find the slightly stiffer cable easier to work with as it 'sits' better.

Unfortunately I'm only doing domestic at the moment so have no reason to stock 1.5

1mm will more than easily take the load of each floor of lights (few years time I wouldn't expect a entire house's lighting load to be more than 100w), might even drop down to 3amp MCBs....just because :lol:

I use 1.5 for high load lighting ie 8- 10 down lights, other than that standard ceiling roses, stick to 1.0
