Hmmm How long is long ?
When you trip out a generator farm in the middle of rural Bosnia and the army get twitchy as there are some not nice individuals outside. Kitchen main board tripped - this was our main load so the gen sets thought Yep time to cool off awhile - so the all shut down apart from the lead set. Little knowledge comes along sees the tripped breaker and resets it. Chaos as the gen set tried to supply the load, the others wake up and start but they have no hope in syncing up with dancing one which eventually trips. So a few momnets of dancing lights and then darkness and then a hell of a lot of scared squaddies.
Our huts were at the opposite end of the camp but we had the torches and we were running. Lead set blew a few fuses and took out a control card so we'd to re config another set as lead get her started and onto bus, then we had to get lights on. talking a good 15 minutes or so. The topbrass with floating about except for the one that flicked the breaker back on. If only he had shut it down again wed have managed to scape through. It was a brown toruser that one, but we were treated to a few beers once we'd got the lights back up.
Next thing wed a few notices put round on our switchgear indicating that on no account should it be touched and in the akward areas there were a few padlocked covers attached.
We spent a good few months after the incident putting up emergency fittings and a few distributed back up ligthing towers that would start if the power went down.
