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.
• Two 16A service - minimum twelve guage copper wire per line (each).
• 30A service – minimum ten gauge copper wire.
• 40A service – minimum eight gauge copper wire.
• 50A service – minimum six gauge copper wire.
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 mal-
function. If non-copper wire is used at any point, we do not recommend servicing
the spa until an electrician replaces it with the proper gauge copper wire.
Important
This service must be single phase. Any abnormal voltage reading requires an elec-
trician. Do not attempt to fix these types of problems yourself. High voltage can
seriously injure or kill.
R.C.D. Wiring Check
If a Residual Current Device has recently been installed, a majority of tripping prob-
lems can be attributed to incorrect wiring of the R.C.D. A clear understanding of the
correct configuration is essential. Please refer to the figure on page 15 as needed.
Wiring Check for R.C.D./Service Disconnect
Precautions
In most areas, R.C.D.’s are required for spa installations. In other areas, R.C.D.’s are
recommended for spa installations, but are not mandatory.
If the spa you are servicing was not installed with a R.C.D.,
strongly urge your customer to improve safety and comply
with current standards by installing one.
Note: A suitable R.C.D. may be acquired through your local dis-
tributor.
Important: Remember, high voltage is still
accessible in the house breaker box even
though you have turned off the spa breaker.
R.C.D. Line-in Wiring Check
• Locate the proper circuit breaker and turn it off.
• Remove the cover from the house breaker box. Check the main service
amperage rating to the breaker box. Note: Typically, a house circuit will
require at least a 100 Amp service when a spa is installed.
• From the circuit breaker, locate the brown load wire and the blue neutral wire.
• From the R.C.D. neutral bar, locate the blue load neutral, and the green
ground wire.
• Be sure there are no other appliances on the spa circuit. If there are, service
must be re-wired to supply the spa only.
