ECN Forum Forums General Topics of the Trade General Discussion Area 200 amp Service 3 Phase

I need some clarification on 120/208Y 3Ø 4W vs. 120/240 3Ø 4W Delta.

The scenario is that I will have a 200 amp 3Ø service coming into the main distribution panel.

1. For 120/208Y 3Ø 4W, I would be able to get 200 amps/leg at 120V and since this is a Wye, I should be able to get 200 amps at 208V too because of how a Wye is configured.

2. For 120/240 3Ø 4W Delta, amperage wise this should be the same as 120/240V 1Ø where you get 200 amps at 120V and 100 amps at 240V due to how the Delta is configured.

Am I right or wrong in my understanding of the difference between these two types of 3Ø power as far as the amperage is concerned?
