75 °C
2 or 3-Wire Cable, 60 Hz (Service Entrance to Motor - Maximum Length In Feet)
Lengths in BOLD only meet the US National Electrical
Code ampacity requirements for individual conductors
60 °C or 75 °C in free air or water, not in magnetic
enclosures, conduit or direct buried.

Lengths NOT in bold meet the NEC ampacity
requirements for either individual conductors or jacketed
60 °C or 75 °C cable and can be in conduit or direct
buried. Flat molded and web/ribbon cable are considered
jacketed cable.

Cable lengths in tables 11 & 11A allow for a 5% voltage
drop running at maximum nameplate amperes. If 3%
voltage drop is desired, multiply table 11 and 11A lengths
by 0.6 to get maximum cable length.

voltage drop is desired, multiply table 11 and 11A lengths
by 0.6 to get maximum cable length.
The portion of the total cable length, which is between
the supply and single-phase control box with a line
contactor, should not exceed 25% of total maximum
allowable to ensure reliable contactor operation. Single-
phase control boxes without line contactors may be
connected at any point in the total cable length.

Tables 11 & 11A are based on copper wire. If aluminum
wire is used, it must be two sizes larger than copper wire
and oxidation inhibitors must be used on connections.

EXAMPLE: If tables 11 & 11A call for #12 copper wire,
#10 aluminum wire would be required.
