208V 3-phase "Y"

[rustydud]

Hello everyone,

I have a control panel.
Power source is 208V, 3-phase, wye power.
From the same power source, I need to power twelve 208V, 3-phase blowers (~7 Full Load Amps each).
From the same power source, I need to power six 120V, 1-phase pumps (~9 Full Load Amps each).

What is the CORRECT way for these loads to be connected to the power source?
Should my loads be connected exactly like this?

Thanks.

And if the answer to my question is "yes",
The neutral in 208Y, 3-phase is grounded.
I need to run line, neutral, plus a ground for my 120V, 1-phase load.
Does this mean that I need to run?

• Line
• Neutral (which is grounded already)
• Ground

...so essentially two grounds?

Rusty are you doing this work yourself or is there an electrician on site.
