Note:
* Indicates single conductor only (not jacketed).
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 allowable length of aluminum
is considerably shorter than copper wire of
same 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 maximum nameplate
amperes. 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).
