20A 6-Terminal Heavy Duty Junction Box 3 5 4 4
20A 6-Terminal Heavy Duty Junc This item fails mainly on its description, it is not a 20A junction box, you could not get 2.5mm conductors under the terminals. If you want a 10A junction box to use with 1.0 mm cable this will do provided that you don't have more than 3 conductors under a screw. I ordered 10 and took 9 back, the 10th one broke when being used. 11 Nov 2013
Expected better! Theses boxes have decent sized terminals, but if you over-tighten them they spread the terminal rendering the post useless. They look the ticket, but don't be fooled by the large brass grub screws, they are soft metal, how do we know, well they are magnetic!! The box is decent in size but are let down severely by the poor quality terminals. I have been a fully qualified electrician for over 50 years now and although I am retiring very soon, consider these boxes are a poor show. If you are considering purchasing these just beware not to over-tighten the grub screws too much, although you must tighten them down to form a positive bonding between connection. Screwfix should really do more research when taking on large stocks of inferior quality products on board. Change your manufacturer, that will wake some of these dosey manufacturers up when they realise their products are not all their made out to be. 17 Apr 2013
Good junction box This box was a joy to use- there is plenty of space to work in, and the terminals perform well when tightening them up. 17 Mar 2013
