CABLE SELECTION
CAUTION: Use of wire size smaller than listed will void warranty.
(*) Meet the U.S. National Electrical Code ampacity only for
individual conductor 60ºC cable. Only the lengths without * meet the code for jacketed 60ºC cable. Local code
requirements may vary.
Maximum lengths shown maintain motor voltage at 95% of service entrance voltage, running at maximum nameplate amperes. If service entrance voltage will be at least motor nameplate
voltage under normal load conditions, 50% additional length is permissible for all sizes.
This table is based on copper wire. If aluminum wire is used it must be two (2) sizes larger. Example: When the table calls for #12 copper wire you would use #10 aluminum wire.
Single phase control boxes may be connected at any point of the total cable length.
Cables #14 to #0000 are AWG sizes.
