| Reversed
Polarity Switch - Live/Neutral Changeover | |||
|
When hooking up to mains power in foreign marinas it is important to check that the live and neutral wires are in the right order. The two pin plug system can have live and neutral either way round. The Live/Neutral Changeover is wired into the electrical system and monitors the polarity giving a visual indication of the polarity. If it is incorrect an alarm is sounded along with a visual indication you can then switch to correct the polarity before turning on the power to the boat.
23 Reverse Polarity Changeover - article from MMM magazine. First recommended by MMM in 1991, the Live/Neutral Changeover switch is still sold in its hundreds every year at home and abroad. Mounted in a box the size of a domestic, surface-mounted light switch, the device has an LED, which shows green if the live neutral wires incoming from the mains to the 'van are the right way round. If they are reversed, the LED is red and the buzzer sounds continuously. Operating the switch on the box reverses the connection if necessary. The device can draw attention to other faults in the supply, such as absence of an earth connection. The switch is inserted in the mains cable before the RCCD and consumer switches, so that the polarity can be checked before any mains supply is fed round the 'van. The wiring must, of course, be carried out or verified by a qualified electrician. |
