[QUOTE="kakrakas, post: 554287, member: 37872"] [USER=490]@binky[/USER], regarding low voltage instances here in Greece it depends. In mainland Greece and in all of the major city centers it is rare. However, on the islands it is more frequent particularly during high load periods during the summer. This is particular worse for houses located far from the transformer. The loss of neutral situation is not something that happens often, but considering the expensive damage it can cause to equipment it is something that makes sense to have as an additional protection. Occasionally, some well informed customers actually ask us about voltage monitoring relays. ;) [USER=1497]@poni[/USER]. Yes the relay should be rated at least the same rating as the main switch of the consumer unit (40A in my case). The reset switch is not needed as the voltage monitor has automatic reset once the fault condition is not present. Though, there are relays with auxiliary bypass switches. [/QUOTE]
