For Hot Spring & Tiger River spas
This Cutler Hammer sub panel comes complete with two GFCI breakers, one 20amp 115volt (single pole single throw) and one 30amp 230volt (double pole double throw). This sub panel is used to convert a 115volt/230volt convertible Hot Spring or Tiger River to 230volts (also referred to as 220). All Hot Spring and Tiger River spas, manufactured after 1996 have an IQ control box and can be converted to 230 volts. Those models were shipped from factory with a 120volt plug in style power cord. If you’re converting your spa to a 230 volt installation, then the power cord is removed and the spa is hard wired. The wiring diagram for your spa model is on the backside of the IQ Control Box front cover. Converting your spa to a 220 volt installation should be done by a qualified electrician and done to code paying special attention to the manufacturers specs, even if you don’t pull a permit. A 230volt powered Hot Spring or Tiger River spa will heat about 8 degrees an hour (versus 2 degrees an hour) and the heater will stay on during the operation of the jet pump. Because all Hot Springs and Tiger River spas are so well insulated, typically there is not a need to convert them to 230volts. If your spa is used for entertaining, with the jet pump running hours at a time, or your spa is located in a freezing and windy climate, then a 230 volt installation may be preferred.
Warning: Some electricians will recommend just using a 50amp GFCI breaker and a four wire supply (instead of the needed 6 wires) to your spa. This is dangerous. It will cause both circuits inside the spa to only trip if a component pulls 50amps instead of 20amps or 30amps before the breaker cuts power to the spa. This in effect could catch a failing component on fire as well as the entire spa. Don’t do it!
