[QUOTE="Phoenix, post: 547276, member: 8133"] I think sometimes its closed through a contactor and may just need some settings change, chances are it was run sync'ed with others and you'd only want one N-E bond in the system. Has this before on an event, got hold of the chaps doing the generators and got very quickly sorted. Can't remember if it had anything to do with it being set wrong, but the enc client was a bit paranoid about loosing supply and was originally down for two sync'ed sets where each one could easily handle the loading. I eneded up convincing them that they'd be fine with them set up with a non running backup on auto start/failover, as even if it took a couple of minutes for the backup to come online, the EPOS systems would be held up by the UPSes and the refrigeration equipment would be fine with that sort of gap. The cause of the paranoia was a previous issue whih had nothing to do with genearators stopping, but the previous gnerator company providing a distro that was really a TPN DB on a frame, full of single pole RCBOs downstream of the generators earth leakage really, and then someone managed (unknowingly) to magale the flex on a piece of equipment [/QUOTE]
