Wiring Checks
WIRING CHECK PRECAUTIONS
When working in a system box always be aware that it may
UÊ
contain high voltage.
Always keep your fingers and hand tools away from any
UÊ
wiring or circuit board when the power is on. Touching any-
thing in these areas can result in serious injury.
All service calls, no matter how minor, should include a
UÊ
complete wiring check, beginning with the house breaker.
CHECK FOR LOOSE CONNECTIONS OR DAMAGED
WIRES
Make sure the power is off before you touch any wiring.
UÊ
Once the power is off, carefully examine all wires for cuts or
UÊ
defects.
SYSTEM BOX WIRE GAUGE CHECK
When inspecting the wiring for any control system, note that
connections for the incoming wires are clearly labeled at the
main terminal block.
30A service – minimum ten gauge copper wire.
UÊ
40A service – minimum eight gauge copper wire.
UÊ
50A service – minimum six gauge copper wire.
UÊ
These wires must connect the house breaker box, through the
local disconnect, to the main terminal block. The wiring diagram
inside the system box shows the main terminal block as TB1.
IMPORTANT
Using non-copper wire can be dangerous, and also can be the
cause of a spa’s malfunction. If non-copper wire is used at any
point, we do not recommend servicing the spa until an electri-
cian replaces it with the proper gauge copper wire.
IMPORTANT
This service must be single phase. Any abnormal voltage read-
ing requires an electrician. Do not attempt to fix these types of
problems yourself. High voltage can seriously injure or kill.
