I have a hot tub that I'm getting set up and it can be wired with 110 or 220 volts. I want to weigh the options and need to understand the benefits of each option. At this point I know that wire and breaker for 110 will be quite a bit cheaper. The amperage rating at 110 is only 20amps and a single pole GFCI breaker and the thinner guage wire will be significantly cheaper than the double pole 50amp breaker and the heavier wire that I would need for the 220 option. This is about all I understand about the differences. I have this vague notion that the 220 will be cheaper for me in the long run but I'm not certain why. Could someone help broaden my understanding of the two? Thanks ahead of time, E
