Caution
Use of wire size smaller than listed will void warranty.
Notes:
• If aluminum conductors are used, multiply lengths by 0.5. Maximum allowable length of aluminum
is considerably shorter than copper wire of the same size.
The portion of the total cable which is between the service entrance and a ∅3 motor starter 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.
• Cables #14 to #0000 are AWG sizes, and 250 to 300 are MCM sizes.
