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 breaking capacity of the Wylex plug in MCBs were rated at 1.5kA and 3kA which may not be strong enough to withstand the possible fault currents relying on the service fuse to absorb the enrgy let through.

    That really shouldn't be a worry in domestics - since the CU will likely have a overall 16kA conditional rating anyway.
