⑤ Reduce lengths by 13% for 200 V systems. ⑥ Lengths in bold require 90ºC wire. Shading indicates 40º C maximum ambient. * Wire does not meet the N.E.C. ampacity requirement.

The lengths in each of the Wire Sizing tables represent 100% of the allowable voltage drop when motor is running at full load.
When sizing wire, the voltage drop of each wire segment must be included. The total must not exceed 100% of the allow-
able drop. Take for example a 1.5 HP motor with a distance from Service Entrance to Controller of 100' and 500' between the
Controller and Motor.
• Service Entrance to Controller = 100' of 10 AWG (100/455) = 22 % (455' is from the S.E. to Controller chart)
• Controller to Motor
= 500' of 12 AWG (500/709) = 71 % (709' is from the Controller to Motor chart)
Total Drop (must be ≤ 100%) 93 %
If the distance from the Controller to Motor was 600' (600/709) = 85% + 22% = 107%, we would need to use #10 wire for that
segment, ex. 600/1126 = 53% + 22% (for 100' of #10) = 75% which is acceptable. It is also acceptable to use different wire
sizes for the Buried and Well sections of wire.

➀ Supply voltage must be 196 VAC – 265
VAC.
➁ Shaded areas indicate which controller
models can be used with which motors.
Lighter shading indicates combina-
tions where controller will limit peak
performance to 85% of catalog value for
pump/motor.
➂ Circuit Breaker or Dual Element Time Delay
Fuse Size (Amps) protecting branch circuit
supplying controller.
➃ Minimum size of single phase 240 V
generator required.
