WIRE SIZE
General All wire should be stranded. The AC wire size for power of the system must be
14 AWG or larger. This gauge of wire will be sufficient for runs of up to 300 feet
from the breaker panel to the system. Sites with distances over 300 feet must
use 12 AWG wire or larger.
Suction Pump The AC wire size for a suction pump is dependent upon the HP rating of the pump
motor, the voltage at which the pump will be operated (115/230), and the distance
from the circuit breaker panel to the pump. Use the chart below (Figure 5-6) as a
guide in selecting the proper size wire for your installation requirements. The wire
size for the switch detect from the pump should be 14 AWG.
Dispenser The AC wire size for the control lines of a dispenser should be 12 AWG. These
control lines are used to supply power for the reset mechanism, solenoid valve,
and submersible starter relay (when the submersible pump is not directly powered
by the dispenser). The wire size for the submersible pump power is dependent
upon the HP rating of the pump motor, the voltage at which it will be operated
(115/230), and the distance from the circuit breaker to the pump. The chart below
should be used as a guide in selecting the proper size wire according to the
specific installation requirements. The wire size for the switch detect from the
dispenser should be 14 AWG.
Pulsers All DC pulser wire size should be 18 AWG. This size is more than enough to
handle the current requirements of the pulser and is primarily used for its
strength.
Communication The wire size and type for the communication wiring should be determined
according to the specific application as described in Section 6, Communications.
