In LV Systems the he neutral of the supply is earthed at the distributor’s transformer. Hence, in systems operating in island mode, the distributor’s neutral-earth link cannot be relied upon, as this is switched out when the live conductors are disconnected. What is then required for an installation in an Island Mode?
Can a polyphase isolator disconnect before a line conductor?
In polyphase systems, the neutral contact of the island mode isolator should not disconnect before those of the line conductors, and should not reconnect after those of the line conductors. As mentioned above a consumer earth electrode is required for island mode operation.
