PE
Symmetrical shielded (or armored)
cable with three phase conductors
and 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 types

PVC
Note: Shielded or armored cable, or
cabling in metal conduit is always
recommended 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 smaller

(8 AWG) Cu, or motors
up to 30 kW (40 hp)
Yes
EMT
Four-conductor cabling in metal
conduit (three phase conductors and
PE), eg, EMT, or four-conductor ar-
mored cable
Yes with motors up to 100 kW
(135 hp). A potential equalization
between the frames of motor and
driven equipment is required. Yes
