Ok...... I had an older spa pump that went out. I also replaced the spa pack. The old spa pack had a GFCI breaker in it and the new one does not. So now I have to add gfci protection to the spa via a gfci breaker. The older main panel (square D) does not make gfci breakers for that style of panel (1980's). So I elminated the hot tub from the main and moved it into an under utilized already existing sub panel.
Here is where I am now lost..... the sub has only one bus bar, all wired attached are grounds, there is NO floating neutral bus bar. I know I can NOT run the breaker (which has a built in "coiled" neutral wire to the ground bus bar or I create a parallel circuit which will feed back current and will not trip the gfci.
So....... Question 1: Can I ground the hot tub in the subpanel and run the neutral into the main panel and attach it there ? Will that create a parallel circuit? Will that prevent the gfci breaker from tripping?
Question 2: If that will not work....... OPTION A: is there a way to ground the subpanel, (grounding rod) and mount a new bus bar to ground box and use the other bus bar as a neutral bar. OR OPTION B: how do I create a neutral bus bar in the subpanel...... (if this is the option I need details) I know it needs to float, but where would it connect to in the main panel ? What gauge wire would be needed?
More info..... the main panel does not have a Main disconnect breaker, the sub panel is being fed from a 60 AMP breaker in the main panel that has two wires from the breaker to the subpanel lugs, a ground and a neutral in the main panel. The current subpanel (also Square D) bus is a ground bus running to the main panel bus.
Thank you for any and all information, I am NO electrician so any help is greatly appreciated.
