A staright foreward upgrade A nice easy upgrade from older wired fuses. I used the one I purchased to install a fresh circuit for a 9.5Kw shower. Literally a 10 minute task (I have limited mobility). Power off. Two screws to remove the front of the fuse box. One screw to remove the redundant (and unused 15amp fuse holder). Six screws (two per cable) to secure the cables for the new circuit. One screw to install the new MCB holder. A quick re-check and circuit safety check.Two screws to replace the fuse box cover & then slip in the MCB and it was all done. 23 Jul 2015

Make your fusebox safer These are a brilliant piece of kit. Switch off the mains, pull out the old type fuse holders, remove the cover over the fuse holder, replace with the new cover supplied (different colours for different ratings) then plug in the MCB. Switch on and job done! Just ensure that the correct rated MCB replaces each fuse. No more fiddling about replacing fuse wire in the holder. The only drawback, if you can call it one, is that if a bulb blows the MCB MAY trip out, but we can live with that for the additional safety. 12 Mar 2015
