Motor is supplied with a copper ground wire.
Splice this ground wire to a copper conductor
that matches motor wire size specified in
Table V. See Pages 16 and 17 for cable splicing
instructions.
Permanently ground pump, motor and control
box before connecting power cable to power
supply. Connect ground wire to approved
ground first and then connect to equipment
being installed.
Do not ground to a gas supply line.
Fire and electrical shock hazard. If
using a drop cable larger than No. 10 (5.5mm
(for example, No. 8 (8.4mm
pump and control box, run cable to a separate
junction box. Connect junction box to control
box with a No. 10 (5.5mm
(depending on amp rating of pump – see Table II,
III, or IV).
For more information, contact your local code
officials.

WIRING CONNECTIONS:

Installation must meet United States National
Electrical Code, Canadian Electrical Code and
local codes for all wiring (as applicable).
Use only copper wire when making connections
to pump and control box.
To avoid over-heating wire and excessive voltage
drop at motor, be sure that wire size is at least as
large as size listed in Table V for your
horsepower pump and length of wire run.
NOTICE: See Pages 11 through 15 for typical
wiring hookups and control box identification.
NOTICE: When built-in overheating protection
is not provided, install an approved overload
equipped motor control that matches motor
input in full load amps. Select or adjust overload
element(s) in accordance with control
instructions. When built-in overheating
protection is provided, use an approved motor
control that matches motor input in full load
amperes.

SURGE ARRESTERS IN CONTROL BOX
Grounding: When the box has a surge arrester,
the surge arrester MUST be grounded, metal to
metal, all the way to the water strata for the
arrester to be effective. Grounding the arrester
to a driven ground rod provides little or no
protection for the motor.
NOTICE: Surge arresters DO NOT protect
against direct lightning strikes.
Install grounded surge arresters to protect pump
from high voltage surges. Install arrester on the
incoming power line to control box or pressure
switch, as close to pump motor as possible. See
Figures 1 and 2 for installation wiring diagrams
for arresters.
NOTICE: Ground the arrester with a No. 10 or
larger bare wire. Ground according to local
code requirements.
NOTICE: If surge arresters wired into the control
box are against local electrical code, contact
power company for correct wiring information.
