WYLEX 40A SP Type B Curve MCB Excellent device, easy to install and intrinsically safe for user. Excellent value and customer delighted worth it. No more fuse wire! Would recommend this to anyone either in the trade or a DIY person 15 Dec 2014
Fuse upgrade Installation of new shower meant the old 30 amp fuse was inadequate. It was good to still be able to get the 40A MCB to fit the old WILEX "consumer unit" 29 Dec 2013
Fuse Wire replacement This is an excellent product to replace an old fuse wire , which is quick and easy - not to mention safe, for a housewife who does not "do" tools - to reset. An excellent way to keep an old fusebox ticking over, before a new consumer unit can be justified. 9 Sep 2011
