EICR - Old Rewireable Fuse boards are these acceptable?

Former Community Member

Hi, 


I need verification that it is ok to keep old style Wylex rewireable fuse boards to pass the EICR. Initially the electrician said this was ok providing they have a cover for the fuses. However he has now changed his mind and saying they need to be replaced with a new consumer unit. Some of the homes do not have a cover on the fuse board and others have had the cover taken off so plug in mcb's can be accomodated. Is this still ok?

    There's nothing in principle wrong with BS 3036 fuses - they're still specifically listed as acceptable in today's regulations (along with the diameter of tinned copper fuse wire to use).


    On their own however they're likely to be lacking modern facilities - such as 30mA RCDs or perhaps SPDs. These however could be added as in separate enclosures if required.


    Lack of 30mA RCD additional protection is likely to be a C3 in most cases - but can be a C2 for things like sockets likely to feed equipment outdoors or for bathroom circuits together with a lack of supplementary bonding for instance.


    The lack of a cover over the fuse carries isn't ideal - they are after all only semi-enclosed and so arc products can be ejected from them if a fuse blows (hence the warning to switch off before handling fuses embossed into most of them) - but even then I probably wouldn't go for a C2 unless it was in a particularly flammable area. Where the fuse wire carriers have been replaced by plug-in MCBs I think it's less of an issue.
