1.5mm² is not harder to use.1.5 mm is oversized, harder to use, costs more, and is a waste of the planets valuable supplies of copper.
Of course it is. It is thicker and stiffer.1.5mm² is not harder to use.
If a DIYer wants to keep some cable "in stock" it may be less of a waste of resources to have only 1.5mm² and not both.
Agreed. However, as eric has said, it can be more difficult to get 1.5mm² conductors into the diddy terminals of some light fittings/accessories, particularly if/when there is a need for more than one conductor in a terminal.you can bend 1.5mm with your fingers so it is nonsense to speak of it being hard to use due to stiffness.
So have I, but it's not that easy to break them, provided one has a modicum of 'skill' in knowing how tightly to tighten terminal screws.I've heard some clumsy people are more prone to breaking 1mm
True, one could easily 'manage' without 1.5mm² - but it is 'overkill' for immersion circuits, fused spurs etc. (and, as per this thread, even for unfused spurs supplying one single socket).Why does a DIYer ever need 1.5mm cable? He needs 1.00 mm for lighting, 2.5mm for sockets and immersiom, 4mm for cooker, and 6mm for shower. Could dispense with 4mm and use 6mm for cooker.
Not for all installation methods - 1mm² is inadequate for circuits like that in more instances than 1.5mm².True, one could easily 'manage' without 1.5mm² - but it is 'overkill' for immersion circuits, fused spurs etc.
Yes, I should have added a "some", or "most".Not for all installation methods - 1mm² is inadequate for circuits like that in more instances than 1.5mm².
