Recently there was a posting from Dean Filgate about 600 amp v 850 amp line
breakers, I can't find the actually posting at the moment; might have
deleted it.

Anyway a very recent discussion with a retired engineman and spark driver
of many years, brought the comment that he had no knowledge of the 850 amp
line breakers, neither did a spark driver friend of his, so we are all
wondering just where that information comes from.
