CONNECTING THE POWER SUPPLY
CAUTION: DO NOT ENERGIZE THE MAIN CONTROL CENTER UNTIL ALL
ELECTRICAL CONNECTIONS HAVE BEEN MADE.
TO CONNECT THE BASIC 20-50A MAX SYSTEM USING A 20-50A 3 WIRE PLUS GROUND
GFCI CIRCUIT BREAKER (SEE CHART ON PAGE 10 FOR WIRE SIZE OPTIONS)
1. There should be 4- #6 AWG conductor (assuming 100' or less in length) exiting the 1” conduit in the high
voltage compartment of the Main Control Center. Additional #12 AWG conductors (also assuming 100 or
less in length) may be exiting as well if Expander Circuit Board power supply wires were run inside the
conduit. The #6 conductors should be red, black, white and green in color.
2. Cut the wires to length and strip 1/2" of insulation from each wire and connect to the line terminals marked
red, black and white. Connect the green wire to the terminal marked “GROUND.” Tighten all terminals
securely.
TO CONNECT THE EXPANDER CIRCUIT BOARD USING TWO 20A MAX 2 WIRE PLUS
GROUND GFCI CIRCUIT BREAKERS
1. If both loads on the Expander Circuit Board are 120 vac, there should be 6- #12 AWG conductors (assuming
100' or less in length) entering the high voltage compartment. They should be black, white and green in color (2
each color).
If both loads on the Expander Circuit Board are 240 vac, there should be 6- #12 AWG conductors (assuming
100' or less in length) entering the high voltage compartment. They should be red, black and green in color (2
each color).
If the loads on the Expander Circuit Board are 120 vac and 240 vac, there should be 3- #12 AWG conductors,
black, white, and green and 3- #12 AWG conductors, black, red, and green (assuming 100' or less in length)
entering the high voltage compartment.
2. Cut the wires to length and strip 1/8" of insulation from each wire and connect to the line terminals on the
Expander Circuit Board marked “AUX 5”, red, black or white and “SPA AUX BUTTON”, red, black or white as
required. Connect the green wire to the terminal marked “GROUND.”
“ALWAYS HOT” CIRCUITS
The Main Control Center does not provide for the connection of “Always Hot” Circuits. The power supply for
these circuits should originate in the Main Power panel and be protected by appropriate branch circuit GFCI
breakers. These circuits may be routed into and out of the Main Control Center, but must not be electrically
connected in any way to the Main Control Center or to the Main Control Center power supply.
