An electrical system with a fuse on the neutral conductor and on the energized (hot) conductors, is called a "Fused Neutral System" and: is twice as safe as a system where only the energized (hot) conductors are fused. should have the neutral conductor fuse sized to one half the normal ampacity for the circuit. is over fused up to 50% if used only for lighting. is hazardous and should be corrected
