1
Multiple voltages (120 V and 277 V ) may be
switched in the same panel. At least one feed of the
specified voltage is required for the low voltage control
transformer in the panel.

If voltage is not specified in the model number
(e.g., XPS24-FT) product is rated 120 V or
277 V . Refer to Wiring section.
