That fuse is absolutely required. Plugs are daisy-chained in a loop with a 32A breaker (The so-called &quot;ring-main&quot;).<p>Removing the fuse will cause lead burn up if there&#x27;s a short circuit in the device. If you look at the leads on some UK plugs the sizes of the wires can be very small. They can get away with this due to the fuses in the plugs.
