PREFACE
1.0.1 Electrical Requirements
All Spa electrical wiring should be performed by a licensed electrician and must comply
with all NEC (National Electrical Code) and state and local code requirements.
The electrical loads for connections to this system MUST NOT exceed the rating
specified in this manual. Failure to comply with these specifications and/or improper
wiring may cause hazardous operating conditions and/or damage to the controller.
1.0.1.1 Ground fault Circuit Interrupter (GFCI)
Since January 1994, a Ground Fault Circuit Interrupter is required by all electrical Spa
installations. The National Electrical Code (NEC) also states that a service disconnects
should be located near the Spa but no closer than 5 feet. A GFCI could be used for this
purpose.
All 120 Vac Spa require a dedicated 20 Amps GFCI service connection, all 240 Spa
require a dedicated 50 Amps GFCI service connection with a 6/3 AWG (four wire) all
copper conductors. In order to conserve electricity we recommend using 240 Vac
connections in all 240 Vac capable Spa.
It should also be verified that a dedicated service is used with no other circuits
connected to it.
1.0.1.1.1
GFCI In- line wiring
•
Black and Red wires feeding the GFCI are connected to a properly sized circuit
breaker.
•
White wire should be connected to the neutral bar and the Green is connected
to the ground bar.
1.0.1.1.2 GFCI 240Vac 3 wire circuit
A 240 Vac 3 wire service could be used if it does not operate any 120 Vac devices.
•
Black and Red wires feeding the GFCI are connected to a properly sized circuit
breaker.
•
White wire is not required and the Green is connected to the ground bar.
