Installing Your Spa
Connecting the Equipment Pack to Your Power Source (cont.)
NOTE: All spas and associated electrical components must be protected by Ground Fault Circuit
Interrupters (G.F.C.I.) in accordance with the National Electrical Code, Article 680-42, January 1, 1994.
1. Have a licensed electrician run the required power line from the residential circuit breaker box
to the G.F.C.I. disconnect. Wiring should follow national and local codes. The following wiring
diagram shows an example of a G.F.C.I. hook-up (see figure 8 ).
NOTE: Always route wires through a proper electrical conduit to and from the G.F.C.I.
Figure 8: G.F.C.I. disconnect hook-up diagram
Notice in the diagram that all wires except the ground wire (green) must be routed through the
G.F.C.I. including the neutral wire (white).
NOTE: Never bypass the neutral wire. If it is not included in the G.F.C.I. hook-up, then the current will
be unbalanced and cause the G.F.C.I. to trip.
2. Run the wires from the G.F.C.I. to the equipment pack.
3. Connect wires to the spa electronics/control module.
DANGER! Do not turn on electrical power until all electrical work has been inspected.
