Recommended AC output power cable types
The power cable types that can be used for the inverter AC output are represented below.
Note: An equal number of each phase must be in one conduit to prevent conduit
heating due to eddy currents.
Not allowed AC output power cable types
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. The shield must meet the requirements of IEC 61439-1.
Check with local / state / country electrical codes for allowance.
Symmetrical shielded cable with three phase conductors and a concentric PE
conductor as shield. A separate PE conductor is required if the shield does not
meet the requirements of IEC 61439-1.
Symmetrical shielded cable with three phase conductors and symmetrically
constructed PE conductor, and a shield. The PE conductor must meet the
requirements of IEC 61439-1.
A four-conductor system (three phase conductors and a protective conductor on a
cable tray).
WARNING! Ground all conductive cable supports, cable clamps and
individual conductive items close to cables, such as cable trays.
Symmetrical shielded cable with individual shields for each phase conductor is
not allowed on any cable size for AC output cabling.
