■ Power cable typesPreferred power cable typesThis section presents the preferred cable types. Check with local/state/country electricalcodes for allowance.Use as motor cablingUse as input power cablingCable typeYesYesPESymmetrical shielded (or armored)cable with three phase conductorsand concentric PE conductor asshield (or armor)YesYesPESymmetrical shielded (or armored)cable with three phase conductorsand symmetrically constructed PEconductor and a shield (or armor)YesYesPESymmetrical shielded (or armored)cable with three phase conductorsand a shield (or armor), and separ-ate PE conductor/cable 1)1) A separate PE conductor is required if the conductivity of the shield (or armor) is not sufficient for the PE use.Alternate power cable typesUse as motor cablingUse as input power cablingCable typeYes with phase conductor smallerthan 10 mm2 (8 AWG), or motors upto 30 kW (40 hp).Yes with phase conductor smallerthan 10 mm2 (8 AWG).PVCNote: Shielded or armored cable, orcabling in metal conduit is alwaysrecommended to minimize radio fre-quency interference.Four-conductor cabling in PVC con-duit or jacket (three phase conduct-ors and PE)Yes with phase conductor smallerthan 10 mm2 (8 AWG) or motors upto 30 kW (40 hp)YesEMTFour-conductor cabling in metalconduit (three phase conductors andPE), eg, EMT, or four-conductor ar-mored cableGuidelines for planning the electrical installation 7111
