Neutral :
Neutral is the normal ” return ” wire.
In systems where the load is supplied from only one Hot (or “Live”) wire, the Neutral completes the circuit and carries current back from the load to the power station.
Neutral is a conductor that carries current in normal operation.
Neutral represents a reference point within an electrical distribution system.
Earth :
Earth or Ground wire is a safety protective wire for the human body and electrical equipment from fault conditions.
Earth is a conductor that carries no current in normal operation.
Earth is a conductor that carries current under fault conditions such as insulation breakdown that occurs within electrical equipment.

so if you have solar panels and a 240v inverter on your caravan or cabin (off grid), do you need an earth?
ReplyDeleteYes . because you need to protect human being and electrical equipments from fault condition
DeleteUnfortunately very Stupid explanation of differences.
ReplyDeleteAlso The Schematic diagram is Awufull.
This article states that: "the neutral completes the circuit and carries current back from the load to the power station".
ReplyDeleteHowever, the power station sends power out to the grid using three phase configuration and does not even use a neutral.
So this statement must be incorrect.
I would suggest that a neutral is only used in a single phase circuit configuration and is the center tap in a single phase transformer. Also, the neutral seems to always be bonded to ground. Added: the neutral is not even used if a 220 volt device is used such as an arc welder or 220v hot water heater when powered from a single phase transformer.
Sorry to bother remember you get different supply types from your transformer neutral and earth comes from common point at the transformer regardless of single or 3 phase it has nothing to do with 3 or 1 phase
