Does retrofitting mcbs into an older wylex "fuse wire" consumer
unit need notification?

The plug in ones don't have the same breaking capacity as te fuse wire
so you may need to check they are OK.

The plug in MCBs (if that's what you are using) can't cope with as much
fault current as the more common MCBs or fuse wire.



Erm eh?

But why bother? I haven't had a fuse wire go in 30 years so fitting MCBs
would be a waste of time IMO.

Elderly (tight) rellies can't fit occasional fusewires into old
carriers.


If they are having fuses blow then maybe the circuits need fixing rather
than making them easier to reset without fixing them. I can't see why
they would blow for decades.
