Hot Tub wiring questions with PICS
The image shows a 240 volt 1A circuit that your calling a port. To do a similar arrangement in your new spa for 120 volts you would connect to the center terminal (neutral) (white) and use either of the two hot terminals. Ground doesn't change. So one hot, one neutral, one ground wire for 120 volts.I suspect there may be a fuse or mini breaker involved in the process. I'd call the manufacturer to make sure this won't be considered a warranty nullifying modification.
What are you wanting to operate as there are many codes involved ?
