January 30, 20242 yr Hi all After having my change over switch fail on Friday (it only worked on the eskom input - fortunately) and replacing it I realised that my earth leackage after the inverter is wired as follows: PS - I have three phase - so 2 phases are not backed up and one phase is used for the backed up loads. My question is shouldn't the backed up load E/L rather be wired on the OUT of the change-over switch? As it stands now it doesn't look like my backed up loads have any E/L protection when the change over switch is set to eskom/bypass? The plug on the diagram is just an additional surface mount plug I had put in near the inverter. This plug is obviously also not working when in bypass/eskom. ie. should it rather look like this? Also, should I perhaps have another 32A breaker between the inverter AC out and C/O switch? Edited January 30, 20242 yr by Douw G. Gerber
