Motor Cable Types Acceptable for
200-600 Volt Installations
General
A variety of cable types are acceptable for drive installations. For
many installations, unshielded cable is adequate provided it can be
separated from sensitive circuits. As an approximate guide, allow a
spacing of 0.3 meters (1 foot) for every 10 meters (32.8 feet) of
length. In all cases, long parallel runs must be avoided. Do not use
cable with an insulation thickness less than 15 mils (0.4 mm/0.015
in). Do not route more than three sets of motor leads in a single
conduit to minimize “cross talk”. If more than three drive/motor
connections per conduit are required, shielded cable must be used.
•
UL installations in 50°C ambient must use 600V, 75°C or 90°C
wire.
•
For UL installations in 40°C ambient, 600V, 75°C or 90°C wire is
recommended.
•
Use copper wire only. Wire gauge requirements and
recommendations are based on 75°
C. Do not reduce wire gauge
when using higher temperature wire.
Unshielded
THHN, THWN or similar wire is acceptable for drive installation in
dry environments provided adequate free air space and/or conduit
fill rates limits are provided. Do not use THHN or similarly coated
wire in wet areas. Any wire chosen must have a minimum
insulation thickness of 15 mil and should not have large variations in
insulation concentricity.
Shielded
Refer to table 5.5 for acceptable shielded motor cable types.
