With today's consumer units with MCBs & RCDs which trip out at the slightest sign of trouble, why do we still have fused spurs and plugs with fuses in them which depend on fusewires burning through?
I could understand it when main fuseboxes had wire fuses but why do we still need conventional fuses at the distant ends of circuits?
Is it perhaps to provide some protection in case the MCB fails to operate?
