AC OUTPUT
Figure 3-31 External Ground Point Location of wirebox
When the output of the inverter is connected to the grid, an external AC
circuit breaker is required to be installed to safely disconnect the inverter
from the grid should an over current event occur.
The Grid connection type should be a 4-wire Wye, grounded neutral, the
inverter may connect to the grid via 3 or 4-wires. The neutral conductor
from the inverter to point of interconnection (POI) is optional. A floating
delta is allowed, but ground fault protection must be provided external to
inverter.
Either 3-pole or 4-pole AC circuit breaker (OCPD) may be selected as per
the following table. Selecting a breaker of another size may either result in
nuisance tripping or rejection from the AHJ.
NOTICE:
Always connect the Ground conductor (EGC) before terminating any
of the AC conductors.
