J-300 Series6.0 Power RequirementsJacuzzi® spas are designed to provide optimum performance and flexibilityof use when connected to the maximum electrical service listed below. Minorcircuit board modifications can be performed to allow your new spa to accept anelectrical service other than the factory operation setting. Note: Refer to pages37-40 for circuit board configuration details or contact your authorized Jacuzzidealer.North American J-335, J-345, J-355, J-365 & J-375 Models (60Hz)240V/40A* 240V/50A** 240V/60A***Circuit Breaker (2-Pole): 40A 50A 60ANumber of Wires: 3 3 3Frequency: 60Hz 60Hz 60HzCurrent Draw: 26A 36A 45A* In 40A configuration, the heater will not operate while either jets pumpis running in high speed. Note: pump 2 runs only in high speed.** In 50A configuration, the heater will not operate while both jets pumpsare running in high speed. This is the factory setting. Note: pump 2 runsonly in high speed.*** In 60A configuration the heater will operate while both jets pumps arerunning in high speed.North American J-315 & J-325 Convertible Models (60Hz)120V/15A† 240V/30A† 240V/40A‡Circuit Breaker: 15A, 1-Pole 30A, 2-Pole 40A, 2-PoleNumber of Wires: 3 (15A GFCICord US Only*)4 (Hard WireOnly)4 (Hard WireOnly)Frequency: 60Hz 60Hz 60HzCurrent Draw: 12A 21A 30A* All Canadian spas must be hard wired per CSA Canadian standards. (page 22)† In 15A/30A configuration, the heater will not operate while the jets pumpis running in high speed. The factory setting is 120V/15A.‡ In 40A configuration, remove jumper JP1-2 on the board, to allow the heaterto operate while the jets pump is running in high speed.‡ Caution (For 4-wire 240VAC Heater Operation): Move the red wireon the main terminal strip (TB1) from position #1 to position #3. Makecertain wires are connected exactly as shown in Figure-D (Page 14)before applyng power. Failure to do so will result in damage to thecircuit board and /or related components and void the manufactures’swarranty.10
