Rated 5 out of 5 by from Good replacement for fuse wire Changing a fuse box is usually the best option rather than upgrading one that is old enough to need these. But for a cheaper option and to remove the need for fuse wire, these are great, 2 minutes to change over and fits perfectly

Rated 5 out of 5 by from So simple upgrade. Most impressed with Wylex upgrade from fuses to mcbs idea . So simple and old fuse cover knockout panel easy to remove and clean up with a flat file. Screwfix half the price of some suppliers on line. Say no more.

Can you change one Fuse at a time or do you need to chaneg the whole set in one go?

Asked by: Anonymous
Hi, Yes the fuses can be changed one at a time. They do not all need to be replaced at the same time. Thanks for your interest in Wylex products.

Will this fit any make of board, I have an "old" MEM Memera 3 and teh 5am circuit breaker has disingreated in my hand

Asked by: Dexter2102
Hi, Wiring regulations state that circuit protection products different manufacturers should not be mixed in the same installation therefore the Wylex Plug-in MCB should not be used in this case. We recommend contacting a qualified electrician for advice. Thanks for your interest in Wylex products.

Backplate screw

Hi, I understand that I will have to change the backplate on my old consumer unit. My backplate is held in place by a single screw in the centre, but the picture of the backplate for this mcb shows a single screw on the right hand side. Brian
Asked by: Corrigan
Hi, The position of the screw does not make any difference to fitting the base. If you are unsure on any aspect, you should contact a qualified electrician for the correct guidance and advice relevant to your particular installation.

socket into board

i think i need to get one of these to replace my 5amp wired fuse which when it trips goes with a bang. question is the socket that plugs into the board can i leave the old one in there and use the existing socket into the new ? just a bit wary of turning of the power then tampering with the board

You will need to speak to a qualified electrician.

I have just bought some of these but the pins do not line up with my original fuses. The originals are wider apart. Are they adjustable? Or is there something else I need to make them fit?

Asked by: Korgikeys
It is necessary to change the coloured base in the consumer unit for the white base that comes with this MCB’s. The MCB will then fit. All work must be carried out by a qualified competent person, in accordance with BS7671 2008 17th Edition of the IEE Wiring Regulations and all other regulations, e.g. Building Regulations
