Gateway 2 multiple non-backup circuits

[olej24]

Hi

I have a UK single phase power supply and a PW2 & Gateway setup with multiple backup circuits and 1 non-backup circuit for my ev charger. I’m planning on getting AC installed which would also go on a non-backup circuit. Is it possible to wire two or more non-backup circuits into the Gateway?

Looking at the diagram on p24 of the installation manual there are 3 live lugs on the non-backup side. Can I just connect additional circuits to the spare ones or are these just used for 3-phase connection?

This is my current wiring

I am not familiar with UK wiring standards, but in North America, you could connect a "distribution board" or "sub-panel" to that Non-Backup lug to power multiple circuits, within the applicable limits.

You also asked about the other terminals on the Non-Backup supply. I would expect that if you don't have a 3 phase supply connected, those other two terminals would be dead.

Great thanks for the help. Now you say it, it seems obvious. I hadn’t even thought of that
