In the base bid note 2, it calls for a 240V disconnect.
Which is single phase. Note 2,b, calls for a 50A 2-pole 240V breaker to feed the 240V disconnect. The power that is available is 120/208V 3-phase. Is this feed supposed to be 208V single phase?
Contractor should expect to provide transformer to feed the required 240V disconnect.

In bid option #2, It calls out to feed a new 200A panel from an existing 75kva transformer. During the walk through this transformer was already feeding another 200A panel. There is not enough power to feed another 200A panel from this transformer. Where is another option to feed this panel?
