As suggested in other emails, the start-up current is probably too great for
the supply. The solution is relatively simple. Power the modules in banks -
i.e. ten per switch, and turn them on one after the other.
Our office supply was like this - we'd happilly run on the one circuit
breaker until something overloaded it, then there was no way we could get
that breaker to close again due to all the in-rush currents of the
switchmode PSUs and degausing circuits. EVERYTHING had to be disconnected,
then added one unit at a time after the breaker was closed.
