    Ideally, individual checking and re-forming is good. But it is WAY too "invasive" for standard use.

    Using the bus terminals that are provided for an external brake unit should be fine.

    The tag has been altered from 3 phase, to 1 phase by overstamping the 3 with a 1.

    Hard to know what was done, exactly. It may be as implied, that the 3 phase motor was just re-wired to start up...

    The supply type is mostly irrelevant if you are installing a transformer to get your desired output.

    The secondary of a transformer is a "separately derived system" with no inherent relation to...

    What does a generator provide? What is a "high load"? How long is a string.....?

    Voltage and frequency control is what a generator DOES. "Load" is current flow.

    So they may not be too bad,...

    Lights that fail rapidly are a clue to possible neutral problems.

    Very possible with the wiring type that has two hots and one neutral (known as a "multi-wire" circuit). Something that shares...

    Some third harmonic will not bother rectified supplies, as long as the peak is high enough.

    But if the genset does not like to be overloaded at all, it may not be the best for a rectified supply. ...

    It sounds like a variety of induction generator. Has to have a magnet in it somewhere to get it going. The reference to capacitor excitation is a clue.

    Yes they "work". Used lots of places....

    When I do that, and I have always "mapped" houses I have lived in, I use a LAMP, with a 60 watt bulb.

    Voltmeters will fool you. Even analog ones can fool you, although they are generally more...

    VFDs and computers etc rectify the AC as the first operation. They really do not need super clean AC, despite "urban legends" to the contrary.

    They look like overloads, and would act to open the contactor, normally by opening the control power to the contactor.. That could have something to do with your problem.

    The cutouts can develop a bad connection, or even be damaged when installed. After that, the high resistance of a bad connection will often cause them to open after some undetermined time. ...

    Power should go to the "L" terminals, and motor to the "T" terminals.

    We had a low volume product that we used a Mean Well supply in. That model, at least, kept failing for no particular reason. We put the same rating from a different company in...

    Anything connected to the bus voltage could have fried. Since the controls work, the "housekeeping" supply is good, and the capacitors (replaced) are good.

    Nothing is shorting across the bus. ...

    They usually ARE coated. The silverish look is often from tin, which is resistant to many common corrosive materials, and is plated on the srands to resist corrosion.

    There are folks who run an entire shop off of one VFD. It's a big one, in general, and essentially acts like a Phase Perfect, the frequency does not get changed.
