I think a 3 phase I think a 3phase RCD would be necessary if the load were a 3phase load e.g. a 3 phase motor. However, supplying a household with a 3 phase supply is just to have sufficient power from the 3 phases to supply more (actually single phase) loads. In this case I think either type...

Or maybe the RCDs are not working at all since they are old from the original home installation ?:unsure:. I have to check them. In order to check the RCD I intend to connect a 5w bulb between phase and ground (third pin of the receptacle). That will allow some current to flow from phase through...

in addition when the grid is available it seems that the inverter, beside charging the batteries from the grid, it also switches the output directly to the input which implies connecting the grid neutral to the output neutral anyway.

thanks timselectric for your response. actually yesterday few hours after posting my question, I connected the inverter output neutral to the grid neutral and of course the AC input of the inverter has also its neutral connected to the same grid neutral. I was scared but it worked without...

Hello, I have a 3 phase grid supply and a neutral (4 wires coming from the transformer). Phase to Neutral is 220VAC/50 Hz. I have s single phase Hybrid inverter type Noor Power Plus Model 2SSP3119C 5KVA with two wires for AC input and two wires for AC output. Of course it also has an input for...
