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?

    The actual fuse wire is held pretty snugly in its carrier in an old Wylex consumer unit. If it blows it is unlikely to send molten particles out into space.

    I'm not so sure. When I were a lad it wasn't that uncommon to see scorch marks on the front cover of a wylex CU. If you look carefully at the shields (the colour coded covers that screw down over the terminals) I think you'll see a notch at on the top and bottom edges - which allows the arc products to escape.


    I would agree that the heat seemed to dissipate quite quickly so, and by its nature it's a rather short lived event (unlike say dropping from an arc lamp), so I'd tend to agree it's unlikely to set anything on fire several feet away.
