3.6.1 AC POWER SOURCE TYPES
AC Input power to the IC Series can be supplied from a split-phase or dual-input single phase AC source. These sources typically
include utility power or a generator.
•
Split Phase: This source has 4 lines: 2 Hot Lines, one neutral and one ground. The 2 hot lines are 120VAC
and are 180 degrees out of phase with each other, so that the 2 voltages equal 240VAC. The voltage between
each hot line and neutral is 120VAC and the voltage between the neutral and ground is approximately zero.
Because the 2 lines are out of phase, the currents from each line subtract in the neutral, and the neutral current
will be approximately zero if the loads on each line are equal. For example, if Hot 1 is supplying 20A and Hot 2
is supplying 15A, the current in the neutral will be 5A.
•
Dual Input: This source has 4 lines: 2 Hot lines, one neutral and one ground. The 2 Hot Lines are 120VAC and are
in phase and must come from the same source. The voltage between the 2 hot lines is zero. The voltage between
each hot line and the neutral is 120VAC and the voltage between the neutral and the ground is approximately
zero. Because the 2 lines are in phase, the currents from each line add together in the neutral. For example, if
Hot 1 is supplying 20A and Hot 2 is supplying 15A, the current in the neutral will be 35A.
3.6.2 AC WIRE SIZE AND OVERCURRENT PROTECTION
The wires used for the Input AC and Output AC must be sized to meet local electrical safety requirements. The AC wiring must
be protected from short circuits and overloads by an overcurrent protection device. These requirements are usually met using a
main panel and sub panel (with suitable circuit breakers/fuses installed) located before and after the Inverter/Charger as shown
on pages 30-33.
CAUTION: The IC Series inverters’ internal transfer contacts are rated for 50 amps, The pass-through current
for relay contact must be no greater than 50 amps or damage to this relay may occur.
