2.5.6 AC Wiring Confi gurations
The following table provides the different wiring confi gurations for installing and connecting the
AC conductors to and from the inverter (refer to Figures 2-9 to 2-11 for installation drawings
showing these confi gurations).

Note – AC source is from either the utility/grid power (i.e., shorepower) or an AC generator.

Note – If two legs @120 VAC are used, they must be from the same source (i.e., common
2
neutral) and not in phase with each other. You can use a neutral and two legs from either a split-
phase (120/240 VAC) source or from a three-phase (120/208 VAC) source.
Note – The 'Maximum Input Breaker Required' is used to protect the inverter's internal AC input
3
circuit, which is rated for 50 amps for each input.
Note – The 'Minimum Wire Size (AWG)' is based on the 'Maximum Input Breaker Required' size
4
and the 'Maximum Output Capacity (Standby Mode)' current. If the wire size is reduced, then an
appropriately sized over-current protection device (i.e. fuse/circuit-breaker) would need to be
installed to prevent damage to the reduced sized wire.
