I was watching Guy's 3-phase Quattro installationvideo on Victron Professional and had a question regarding the Neutrals on ACin and ACout.
Does these two Neutrals have to be separated? I know the Neutrals on ACout has to be linked in a 3-phase setup, but is it possible to link also ACin Neutrals to the same busbar as the Neutrals of ACout?
Forexample in a TN-C grid with a combined PEN, PE and N are linked in the switchboard. So ACin would then have PE and N linked already (at the switchboard).
If there is no RCD on the ACout from the quattros, could the Neutral from ACout on the quattro go to the same busbar as PE and N are linked to in the switchboard?
I know best practice is to install a RCD and have Neutral from ACout go to an isolated Neutral busbar in the switchboard. I was just curiouse on if the quattro NEED to separate ACin Neutral from ACout Neutral or if they can operate together on the same busbar.
Also, what dimension is the chassi ground on Quattro 5K 230V? M6 or M8?
