Power cable types
Preferred power cable types
This section shows the preferred cable types. Make sure that the selected cable type
also complies with local/state/country electrical codes.
Use as motor cabling and as
brake resistor cabling
Use as input power cablingCable type
YesYes
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and concentric PE
conductor as shield (or armor)
YesYes
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and symmetrically
constructed PE conductor and a
shield (or armor)
YesYes
Symmetrical shielded (or ar-
mored) cable with three phase
conductors and a shield (or ar-
mor), and separate PE conduct-
or/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 types
Use as motor cabling and as
brake resistor cabling
Use as input power cablingCable type
Yes with phase conductor smaller
than 10 mm
2
(8 AWG) Cu, or mo-
tors up to 30 kW (40 hp)
Yes
Four-conductor armored cable
(three phase conductors and PE)
