Ac Wire Size And Overcurrent Protection; Ac Input And Output Wiring Connections - Apollo Solar 3224 User Manual

4.3.2.1 AC Wire Size and Overcurrent Protection

AC input and output wiring must be sized per NEC (ANSI/NFPA 70) and local electrical safety code
requirements to ensure the wires ability to safely handle the inverter's maximum load current.
Overcurrent protection devices are required to protect the inverter's input and output wiring. Since
overcurrent protection is not included in the inverter, it must be added at the time of installation.

4.3.2.2 AC Input and Output Wiring Connections

Refer to Table 4.1 for proper AC input and output wiring gauge. Connect the wires from the AC
terminal block (refer to Figure 4.3) to the AC circuit breakers. Please observe the proper torque rating
on the terminal block. To avoid confusion (and to conform to code), use white for neutral (N), and
black and red for line (L1, L2) connections. Connect Green wires from the ground (GND) terminals to
the earth ground bus bar.
WARNING
Be sure to bond AC neutral to Ground.
