I have a 277/480V supply to the building. All my lights are designed at 277V, however, all of the devices are 120V.
I have a 277V/480V MDP, then a 150KVA transformer, and then a 120/208V panel for my devices (receptacles, fire alarm panel, etc.).
I have the transformer's Secondary Distribution System set to 120/208V, but I can't figure out how to connect my 120/208V panel to the transformer which in turn is connected to the MDP.
The ultimate goal is to have the 120/208V loads show up in the MDP through the transformer (if you open the Schedule for the MDP you'll see the transfomer and not the 120/208V panel).
Any help would be greatly appreciated.
