| 11. | These plugs are rarely polarized, so you don't have to worry about the neutral wire.
|
| 12. | This can happen when two worn wires, the hot and neutral wires, contact each other.
|
| 13. | The currents returning from the customers'premises to the supply transformer all share the neutral wire.
|
| 14. | This is why only common trip breakers must be used when neutral wire switching is needed.
|
| 15. | Low-cost power strips often come with only one MOV mounted between the live and neutral wires.
|
| 16. | The overloaded neutral wire can cause excessive heat.
|
| 17. | The context makes it clear that points X and Z are the live and neutral wires.
|
| 18. | The link holds the neutral wire at earth potential, so that only the live wire alternates.
|
| 19. | The neutral wire only carries the net difference.
|
| 20. | Later this design was improved by adding a third wire alongside the hot and neutral wires.
