the National Electrical Code (NEC), or

the Canadian Electrical Code, as well as all local, state and

provincial codes.

Install an all leg disconnect switch where

required by code.
The electrical supply voltage and phase

All splices must be waterproof. If using

splice kits follow manufacturer’s

instructions.

Select the correct type and NEMA grade

Failure to permanently ground the pump,

motor and controls before connecting to

power can cause shock, burns or death.

All three phase (3Ø) controls for sub-

mersible pumps must provide Class 10,

quick-trip, overload protection.

4" motors ≥ 2 HP require a minimum

flow rate of .25 ft/sec. or 7.62 cm/sec.

past the motor for proper motor cooling. The following are

the minimum flows in GPM per well diameter required for

cooling: 1.2 GPM/4", 7 GPM/5", 13 GPM/6", 20 GPM/7",

30 GPM/8" or 50 GPM in a 10" well.

Pumps ≥ 2 HP installed in large tanks

should be installed in a flow inducer

sleeve to create the needed cooling flow or velocity past the

motor.
