We then take the total amperage and multiply it by a safety factor of 25% (10A x 1.25) giving us the fuse rating of 12.5A or 15A if we round up to the nearest available fuse size. 240-46 If the bayonet fuse will not be used in series with a current-limiting fuse, an isolation link is required. The fuse's highly efficient currentlimiting section reduces the effects of high fault current stresses on upstream and downstream apparatus because it limits energy letthrough during high current fault clearing.
