This SD200 genset was installed at a school over 2 years ago(not by me) and it is set at 208Y/120. Only problem that no one seems to notice is it needs to be 408/277. This was only discovered during a power outage which started the generator but neither of the 3 transfer switches would transfer to the emergency load because the voltage was below threshold of course. So I'm wondering can I re-strap the unit to output 480 voltages? Lot more to this story but that would be information overload, unless required.
Model# SD200GG178.7D18HPSY3 Serial# 3000755715 Alternator# 0000121513
