Rated 5 out of 5 by Wylex 40A MCB Shower upgrade, installed this MCB in less than 20 seconds, worked first time as you'd expect from Wylex. These babies are life savers!!! Customer was over the moon not having to pay labour and costs of a more expensive consumer unit upgrade. 27 Feb 2016
Rated 5 out of 5 by Wylex plug in MCB Up grading a domestic panel that customer didn't want a new consumer unit at this moment. After the fuse wire blowing for ring main and them sitting all day with no power and they didn't know how to replace the wire I recommended these MCB's as a solution. Only minutes to fit each one and now they can reset them in seconds should one ever trip, no more sitting with no lecky till I can attend. Wylex reliability and good price what more can I say. 13 Feb 2016
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

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.
