I wired a house a few months ago,and the plans and the builder told me to wire for a 120v jacuzzi in the master bathroom. Now when I get there to trim out the house it is a 240v 20 amp jacuzzi. I only have 12/2 with ground ran to it, and there is no way to pull 12/3 with ground to it because it is a 2 story house. The jacuzzi j-box only has 2 hots and a gound coming out of it. So if I install a 2 pole GFI breaker I have no neutral for the breaker. Will it work with out the neutral tied in to the breaker, and only the neutral pigtail tied into the neutral bar???
