WIRE SIZE
Electric Keytrol - Factory Mounted to Top of Pump or Dispenser
When installing a GASBOY Electric Keytrol, wiring of sufficient size is required. When the Keytrol
is mounted directly to the top of a GASBOY pump or dispenser, the Keytrol is pre-wired to the
dispenser at the factory. Field wiring for this configuration may be referenced by the wiring
diagram for your model pump or dispenser.
Electric Keytrol - Remotely Mounted from Pump or Dispenser
When the Electric Keytrol is mounted remotely from the dispenser, use the following Wire Size
table as a guide to determine the required sizes for the AC wiring to the master Electric Keytrol
unit. As shown in the table, the wire size is dependent on the HP rating of the pump motor, the
distance from the circuit breaker to the pump/remote dispenser, and the operating voltage (115 or
230 VAC) of the circuit.
If multiple units are powered from the same breaker through the same wires, you must increase
the gauge of the wires to handle the added load according to the distance from the breaker panel
and the HP rating (if applicable).
AC wiring from a Master Electric Keytrol unit to an Auxiliary Keytrol unit (Hot, Neutral, and
Ground for 115 VAC, or L1, L2, and Ground for 230 VAC) must be 14 AWG minimum, and sized
according to the breaker feeding the Keytrol. Positions 4 through 7 on an Auxiliary Keytrol unit
(marked A, B, C, and D on the terminal block) handle DC current and should be connected to the
Master Keytrol, or other Auxiliary Keytrol Units, with 18 AWG wiring.
The DC wire size for the Pulser lines must be 18 AWG minimum.
