OWNER'S MANUAL
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your Carolina Spas™ models has gone through numerous tests to verify that all of the spa
functions operate . Beyond the tests, your Carolina Spas™ models has been designed to provide
the maximum safety against electrical shock . Read and follow the electrical installation
requirements and instructions completely . The next few pages will assist you in properly
connecting the electrical input . Follow the electrical instructions for your specific spa model .
Serious risks or injuries may occur if the spa is improperly wired .
220 Volt Permanently Connected Models:
• Caswell* • Winston* • Holden • Savannah •Charleston • Asheville • Southport
*This model is convertible to 110V—See page 10 for installation instructions .
Carolina Spas™ must be wired in accordance with all applicable local electrical codes .
Use NEC 250-122(table) and local codes for more information . All electrical work
should be done by an experienced, licensed Electrician . We recommend the use of
appropriate electrical conduit, fittings and wire for all circuits .
220 Volt installations require a 60Hz, single phase, three-wire electrical service plus
ground (Line 1, Line 2, Neutral and Ground) and must be connected using a minimum
supply conductor ampacity of 50 AMPs and a minimum circuit breaker size of 50 AMPs .
Note: Use copper wire only (3 wire with ground; 8 gauge under 50', 6 gauge over 50')
220 Volt model spas must be connected to a “dedicated” 220 volt 50 Amp grounded
circuit . The term “dedicated” means the electrical circuit is not being used for any other
electrical items (lights, appliances, etc .) . If the spa is connected to a non-dedicated
circuit, overloading will occur and nuisance tripping of the GFCI breaker switch at the
house breaker panel will occur .
A ground lug connector is provided on the exterior surface of the spa pack (operations
center) inside the equipment compartment . This is to permit the connection of a
bonding wire between this point and any metal equipment, enclosures, pipe or conduit
within five feet (1 .5m) of the spa . This bonding wire must be at least 8AWG solid
copper wire .
Due to the risk of equipment damage or fire, use only approved pressure-type wire
splicing lugs or connectors suitable for the size and type of wiring used .
