"Be careful if you buy this product as it comes with no busbar or neutral link. BG stockists although not Screwfix will sell you a cable kit part code CUA05 but the cables are too large for the neutral terminal bar in this enclosure! You will have to source your own busbar and create your own neutral link using the neutral core of 10mm twin and earth cable as this is the largest cross section of cable the neutral bar or earth bar will accept. Ensure you are not going to exceed the current carrying capacity of the 10mm neutral link. Don't try 16 or 25 mm meter tails as they won't fit. BG were unaware of this problem until today so hopefully they will look into and rectify the problem with the neutral and earth bars"
