Rated 5 out of 5 by great value need to replace old fuse for shower unit this fitted perfectly simply removed old stlye fuse and replaced with this job done 29 Dec 2015
Rated 4 out of 5 by Replacement fuse Used to protect a shower circuit. Easy to fit, took only a few minutes to swap over. One problem was that the fuse board cover wouldn't fit back over the new fuse because it is bigger than the old one, so I had to doctor the cover to make it fit. Other than that, no problems at all. 28 Sep 2015
Rated 4 out of 5 by easy upgrade so easy to install .Updated my parents fuse box as they are getting older and harder to do things themselves like replace fuse wire in the middle of the night. makes their life so much easier 3 Sep 2015
Rated 5 out of 5 by 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

Answer: 
Hi,
There are a number of factors that affect the maximum shower rating including the size/type of cable used, length of cable run etc. A qualified electrician should be contacted for an accurate assessment of all these elements.
