Wylex plug in MCB fuse replacements, worth upgrading?

Wylex produce a range of miniature circuit breakers (MCBs) that plug into old style household fuse boards. They are sold by a wide range of retailers such as Screwfix as a way of modernising old fuse boxes.


So is it worth investing in these Wylex MCBs and discarding your existing old style fuses?

The first thing that needs to be understood is that just swapping from fuses to MCBs does not create the equivalent of a modern consumer unit, these have built in RCD (residual current device) circuit breakers that add an extra level of life saving safety. If you want to upgrade to the best then getting an electrician to fit one of the latest consumer units is the way to go.

But are MCBs safer than fuses? Well the two basically do the same job in different ways as explained in the video below in which John Ward examines the issue.
