Webbreaks the circuit and disconnects the appliance. For example, if the fuse rating is 3 amps, then a current greater than 3 amps will blow the fuse. We must look at the heating effect of current to understand how a fuse works in more detail. Which Fuse is Correct for an Appliance? If we know the voltage and the power of an appliance WebAC Residual current circuit breakers work by comparing: the current entering the appliance via the live wire with the current leaving the appliance through the neutral wire. The live wire and the neutral wire are wound around iron cores in opposite directions.
