All wiring must conform to applicable guidelines in accordance with all federal, state,
and local codes. Failure to comply with all applicable guidelines could result in an
unsafe installation. Use the following table for maximum wire length to wire gauge
ratios for submersible wiring:
Measure from the bottom of the tank to the top of tank mounting threads. Subtract
the distance for clearance between the PMA and the bottom of the tank (6" [152
mm] recommended). This is the length to which the pump should be extracted,
measured from the bottom of the riser threads to the bottom of the motor end bell.
SETTING
EXAMPLE:
WIRE SIZE
MAXIMUM RUN
10 gauge / 5.26 mm2
650 ft / 198 m
12 gauge / 3.31 mm2
400 ft / 121 m
14 gauge / 2.08 mm2
250 ft / 76 m
Tank + thread measurement
96" (2,438 mm)
Distance from bottom (5" [127 mm]) + riser thread engagement (1" [25 mm])
-6" (-152 mm)
= Length (bottom of riser to end bell)
90" (2,286 mm)

RISER SIZES
Maximum riser size is found by taking the grade to tank mounting thread
measurement and subtracting the manifold height and clearance (6" [152 mm]
clearance recommended).
EXAMPLE:
Grade to tank mounting threads (bury depth)
48" (1,219 mm)
Minus manifold height without leak detector
-11" (-279 mm)
Minus 6" (152 mm) for top clearance (2" [50 mm] minimum)
-6" (-152 mm)
= Maximum riser size
31" (787 mm)
