480V Wye Vs Delta Distribution Panels 6

[engineerithink]

Please help. I am a new engineer which explains the simple question. When purchasing a distribution panel to be fed by 480V delta 3 phase 3 wire is it okay to buy one rated for 480V wye 3 phase 4 wire? Are they always interchangeable? What differences would I have to look out for?

Thanks,

Thanks for the sentiment. I have found, after working now for 5 different electrical equipment manufacturers, that most of them hire MEs as salespeople, not EEs, even though they are selling electrical equipment. Mangers tell me it's because they want people who understand how machines work, not how the electrical equipment does. My theory is that they don't want people who can question the decisions often made for marketing reasons, the above being a case in point. I am not a salesman per se, I am the technical backup for our salesmen, and I think I am the only EE in the building!
