Electrical Requirements 230V spas
Please refer to your spa's owner's manual for complete details and instructions.
DO NOT POWER THE SPA WITHOUT FIRST FILLING WITH WATER!
DANGER – RISK OF ELECTRIC SHOCK
Installations that do not conform to the following procedures and requirements may expose users to electric
shock. Nonconforming installations will not be covered under warranty.
If installed in the United States, the electrical wiring of this spa must meet the requirements of the
National Electric Code (NEC) and any applicable state or local codes. The electrical circuit must be
installed by an electrical contractor and approved by a local building electrical inspection authority.
1. Installations within 5 feet of any metal surfaces must ground the metal surfaces to the spa. Use an 8
AWG solid copper wire and attach it to the grounding lug on the power pack, located in the equipment
compartment. Only a licensed electrician may install power to the spa.
2. Power supply installation must include a suitably rated ground fault interrupter (GFCI) as required by
NEC Article 680-42. The circuit breaker must be dedicated and should not be shared with any other
appliances. It must be labeled and easily accessible to users.
3. The electrical supply for the spa must include a suitable rated switch or circuit breaker to open all
ungrounded supply conductors to comply with Section 422-20 of the National Electric Code, ANSI/NFPA
70. The disconnecting means must be readily accessible to the spa’s occupant but installed at least 5 feet
from the spa water.
4. Power supply lines must be hard wired into the power pack. DO NOT use extension or plug type cords of
any kind. The use of a shut-off box near the hot tub is also recommended. This box provides a quick and
convenient method to shut off power to the hot tub for emergencies and maintenance.
5. Supply lines must be properly sized as per the NEC (National Electric Code). A ground line must be
provided that is as large as the largest current carrying conductor, but no less than 8 AWG. Use copper
wiring only.
6. Please open the front cover of the control box, and follow the instructions and wiring diagram printed on
the backside.
7. CAUTION, 230V POWERED SPAS – These spas must be hard wired to your household electrical
service box only. Do not use an extension cord or any other disconnect-able
power cord. The use of an
extension cord or a disconnect-able power cord is highly dangerous and will void all warranties!
• Wire size must be appropriate per NEC and/or local codes.
• Wire size is determined by length of run from breaker box to spa and maximum current draw.
• THHN copper core wire is recommended.
• All wiring must be copper to ensure adequate connections. Do not use aluminium wire.
CIRCUIT BREAKER REQUIREMENTS:
A new GFCI circuit breaker must be used for your spa installation. Do not use an existing breaker,
as its condition is unknown.
BREAKER 230V
Capacity 40 amps
# of wires 4
On 230V systems always use a 4 wire system. ON all systems, the spa must be connected to a
dedicated GFCI circuit breaker that is not shared with any other equipment. Do not use extension
or plug type cords of any kind.
