A.O. Smith Century Pool & Spa Motor - Manual (Page 16)

The task of wiring
your motor is fairly
simple. The wiring
diagrams shown on the following pages are color- c o d e d
for easy reading. The appropriate part number is listed
in each illustration, just in case you need to order the
complete wiring diagram or connection label sticker
for your motor. Make sure the connections are tight
to prevent failure or overheating. If you do find loose
connections, check for excessive vibration.
Without proper gro u n d i n g
of a motor, serious elec-
tric shock is possible. A grounding conductor should
always be connected under the green grounding scre w,
which is located within the terminal compartment of the
m o t o r. National and local electrical codes are import a n t ,
and should be adhered to when working
on a motor.
I n c o rrect voltage at the
motor terminals can cause
the motor to overheat. It’s a good idea to check the
electrical supply wires to confirm that they are suff i c i e n t
to handle the motor load. For example, if you’re using
a 1-
1 ⁄
2
Hp motor at 115 volts over a distance of 150 feet,
use #8 wire. If the motor can be installed to
operate on 230 volts, #12 wire should be sufficient
for a 150 foot distance.
