Symmetrical shielded cable with three phase conductors and a
concentric PE conductor as shield. The shield must meet the
requirements of IEC 61800-5-1, refer to page
48 . Check with local / state
/ country electrical codes for allowance.
Symmetrical shielded cable with three phase conductors and a
concentric PE conductor as the shield. A separate PE conductor is
required if the shield does not meet the requirements of IEC 61800-5-1,
refer to page
48 .
Symmetrical shielded cable with three phase conductors and
symmetrically constructed PE conductor, and a shield. The PE conductor
must meet the requirements of IEC 61800-5-1, refer to page
48 .
A four-conductor system (three phase conductors and a protective
conductor on a cable tray) is
not permitted for motor cabling (it is
permitted for input cabling).
A four-conductor system (three phase conductors and a PE conductor in
a PVC conduit) is
permitted for input cabling with a phase conductor
cross-section less than 10 mm
2
(8 AWG) or for motors < 30 kW
(40 hp) . Not permitted in the USA.
Corrugated or EMT cable with three phase conductors and a protective
conductor is permitted for motor cabling with a phase conductor cross
section less than 10 mm
2
(8 AWG) or for motors < 30 kW (40 hp).
Symmetrical shielded cable with individual shields for each phase
conductor is not permitted in any cable size for input or motor cabling.
