So, to recap: I've got some Very Important Stuff presently operating under conditions that it should never, ever be subjected to. There's not a darned thing I can do about it, either, other than make adjustments to the thing that powers said Very Important Stuff, and which will have a negative effect on my employer's product. They will, however, not have as much effect as what will happen if the Very Important Stuff breaks.
To add to the fun, the stuff that's not working is powered by transformers that run on three-phase electricity. The markings on the old ones may not be especially readable. The new ones must be connected exactly the same as the old ones. The new and old ones are not physically identical.
So what am I doing about it right now? What I can: nothing. I'm going to go take a writing class. Perhaps I should think of the class as Plan B.
