1. Table based on copper wire. If aluminum wire is used, multiply lengths by 0.5.
Maximum allowable length of aluminum is considerably shorter than copper wire of same size.
2. The portion of the total cable which is between the service entrance and a motor starter/controller should not exceed 25 % of the total maximum
length to assure reliable starter operation. Single-phase control boxes may be connected at any point of the total cable length.
3. Table based on a maintaining motor terminal voltage at 95 % of service entrance voltage, running at maximum nameplate amperes. In general,
voltage drop should be maintained at 3 V / 100 ft or less.
4. 1 foot = .305 meter (1 meter = 3.28 feet).
Maximum submersible power cable length (max. cable length in feet - starter to motor)
