3.3 Electrical connection
Proper operating voltage and other electrical
information can be found on the pump name-
plate attached to the top of the motor.
• The motor is thermally protected on all three
speeds and no additional external
protection is needed.
• See fig. 3 for proper grounding and supply
power connection locations (115V and
208-230V).
• The terminal connections are toggle/lever
push design. Push the lever down and
insert the field wiring. Push the lever down
and pull to remove wires.
• Next, use care when installing the terminal
box cover with speed switch (rough
handling can damage the run light LED on
the printed circuit board (PCB)). Insert the
Phillips head screw through the cover and
tighten to a snug fit.
• An external "Drip Loop" is recommended in
the electrical wiring harness; see fig. 2.
• Where an external "Drip Loop" is not
possible, or if the wiring enters through the
upward facing (top) surface of the box, then
an internal "Drip Loop" is recommended;
see fig. 3.

Warning!
Risk of electrical shock!
The electrical connection and
protection should be carried out in
accordance with the latest edition
of the National Electrical Code,
local codes and regulations by a
qualified electrician.
The safe operation of this pump
requires that it be grounded in
accordance with the National
Electrical Code and any state,
local governing codes and
regulations.
Ground wires should be copper
conductors of at least the size of
the circuit conductor supplying
power to the pump. Connect the
ground wire to the grounding
point in the terminal box and then
to an acceptable ground. Do not
ground to gas or water supply
line.
All wire sizes should be copper
and size-based on the ampacity
(current carrying properties of a
conductor) as required by the
National Electrical Code or local
regulations. Additionally UL
requires the following wire sizes
to be used: 18-12 Solid or 14-12
Stranded.
Both the power and grounding
wires must be suitable for at least
194 °F (90 °C).
