There is nothing inherently wrong with using edison-base fuses.

Where there is no evidence of tampering or over-fusing, one is still allowed to use the 'original' style plug fuse on existing installations.

Moreover, there do exist circuit breakers that you can place in the fuse holder.

In many circumstances, fuses of any sort are arguably a superior form of protection than circuit breakers, because even the 'time delay' types react much faster than breakers. A lot of the 'selective co-ordination' issues you hear about do not arise when fuses are used.

Customer tampering? There's a reason the box stores sell so many breakers .... and it's not because electrical contractors are taking their business there!
