1. This measures the difference between current flowing through the neutral conductor . 2. The center tap is not distributed to the equipment and no neutral conductor is used. 3. This system is used with 110 V equipment and therefore no neutral conductor is needed. 4. In normal operation, all the current down the live conductor returns up the neutral conductor . 5. Switching a neutral conductor can create a shock hazard. 6. Neutral conductors are usually insulated for the same voltage as the line conductors, with interesting exceptions.7. Lamps with screw bases will connect the shell of the lamp socket to the neutral conductor . 8. Harmonics can cause neutral conductor current levels to exceed that of one or all phase conductors. 9. Each of the hot leads should carry the full load current, and there is no neutral conductor . 10. This is particularly the case for the third harmonic, which causes a sharp increase in the neutral conductor .
