My mains sockets are wired through a 1.5kw (continous)charger/inverter/UPS so that whether or not connected to EHU I always have mains available.
While connected to EHU, even if there is a power cut, there is still an earth on the 3 pin sockets, however when not connected and supply is totally from inverter the sockets will show an earth fault. This is not surprising of course as there is no connection to earth in this case.
Does the panel see any virtue in connecting the mains wiring earth to an earth spike so that appliances will stil be earthed even when there is no connection through EHU?
I have also found some site electric connections abroad do not have the earth connected, even if there is in theory an earth pin.
