   Jon;

   Reading your post from the 7th. I wired a Sundance just a couple of mos ago. I can't see why you need two GFI's in a row. I think you're seeing the options on which amps you can use. Many tubs will run on lower amps but will not allow you to use blower and heat at the same time. A typical install will use 6/3 via conduit off a dbl pole breaker 40amp into a sub with a GFI, then 6/3 to outdoor weatherproof disconnect. Then 4 individual wires thru sealtite into the tub to the control panel ...
   The GFI nuetral is tricky though and I had to call the manuf. There is a neutral pigtail off the GFI that must be wired correctly or the GFI will trip when you power the unit up.

   I have purchased a new hot tub that I am installing. I am comfortable doing residential electrical but there is one thing that I don't understand about the directions. There is a separate sub-panel with a 30 amp double pole GFCI breaker and another 20 amp double pole GFCI breaker, both of which the tub apparantly needs. The instructions say that the "neutral wire from the main service panal should connect to the 20 amp breaker neutral terminal, NOT the neutral bus bar". The illustration seems to show the neutral connected to the bus bar like in any other panal. What's the deal? Please no lectures about how I am going to electrocute myself and my family though.

   *Gee, guy, I'd call the manufacturer on that one, if there's an apparent disagreement between a picture and written text.Jeff

   *Don't GFCI breakers have a neutral wire that goes to the neutral bus bar? Maybe if you attach the main panel neutral to the neutral bus bar, if there is a fault that's not between this breaker and the motor (or whatever it's running) it would miss the fault.But with the supply neutral feeding into the breaker, any fault, anywhere will be sensed by this breaker. Does this breaker act as a main breaker and feed the other one?I've never heard of this and it really doesn't make sense to me either.

   *Ditto on calling the manufacturer. Normally GFCI breakers are wired with the line neutral connected to a designated terminal on the breaker. Better to get clarification from the source before proceeding here.

   *If you do not wire the neutral through the GFCI the GFCI cannot detect the total current flow through the hot and neutral wires and therefore cannot determine if there is current flowing throgh another path, such as your body. The neutral must be wired through any GFCI breaker. If not, it will always trip when current flows.Frank
