Figure 4: 208V 3-Phase, Wye-Connected
NOTE: With a wye-connected secondary, any two of the
legs can be used to provide 208V to the HCS. For example,
L1 & L2, or L1 & L3, or L2 & L3. Leave the unused leg
open. Do not connect it to a Neutral bar, or to Ground. Be
sure the center point is grounded to Earth somewhere in the
system.
