Note:
No asterisk indicates both jacketed cable and single-conductor
cables.
•
The table is based on copper wire. If aluminum wire is used,
multiply lengths by 0.5. The maximum permissible length of
aluminum is considerably shorter than the same copper wire
size.
•
Make sure that the portion of the total cable, which is between
the service entrance and a motor starter/controller, does not
exceed 25 % of the total maximum length to ensure reliable
starter operation. Single-phase control boxes may be connected
at any point of the total cable length.
•
The table is based on maintaining motor terminal voltage at 95
% of service entrance voltage, running at the maximum value
stated on the nameplate.. In general, a voltage drop must be
maintained at 3 V/ 100 ft or less.

1 foot = 0.305 meter (1 meter = 3.28 feet).
