Hi @Nic Holmes,
Did you sort your issue out?
I have the same/similar issue on my Kodak 5.48 OG plus. Every time the utility power returns my Main DB ELD trips.
I didn’t do the install so I need to look in there and trace wiring. I wanted to avoid this for insurance and COC purposes but the installers I used are no longer responding to my communications.
I have a DB for my Solar an AC DB with change over switch and basically I need to figure out how it is connected up.
Any leads will be appreciated.
