CAUTION -- Use of wire size smaller than listed will void warranty.
Maximum lengths shown maintain motor voltage at 95% of service entrance voltage, running at maximum nameplate amperes.
This table is based on copper wire. If aluminum wire is used it must be two sizes larger. Example: When the table calls for #12 copper wire you would use #10 aluminum wire.
Single phase control box may be connected at any point of the total cable length.
