Default Does retrofitting mcbs into an older wylex "fuse wire" consumerunit need notification?

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


Depends on how many GU10 mains halogens there are... they can often take
out a 5A wylex BS3036 re-wireable on failure.

The Wylex BS 3036 rewirable fuses don't provide sufficient
protection for most ring circuits, when you've applied the
derating factor to the cable for using them.


Certainly true for rings wired in old T&E with a 1.0mm^2 earth if there
are any spurs on the ring.
