Default Replacing Fuses with MCBs

wrote:

Currenly we have a traditional fusebox (fuses with fuse wire in ceramic
cylinder) installed and I wonder if it is possible to replace these
hoders with the circuit breaker type where a button pops out? Obviously
these things would have to be the same size and have the same fiitings.
Has anyone done this successfully or would I need a new fuse box?


If you have the traditional Wylex type rewireable fuses:

Then you can get plug in MCBs to replace these:

Note that they are all "B" type MCBs. These are the "normal" type of MCB
that has a quite fast response to fault conditions. Hence they will trip
as often (in fact probably more often) in response to bulbs blowing than
the rewireable fuses you currently have. Saves replacing fuse wire but
still a PITA!

If you replaced the consumer unit with a more modern one then you could
use type C MCBs for the lighting circuits. This may reduce the number of
times you get spurious trips.
