I am looking for a hot tub that uses 3 wire, 240 electrical supply. That is what my old one uses, and I don't want to run new wires. Will this one work? If not, can you suggest another? Thanks.

Hello Judith and thank you for your inquiry. I believe all hot tubs these days use 240 volt 4-wire connections, as it is a national code. That consists of 2 hot wires, a ground and a neutral.
