220V - 50Amp GFCI Breaker

2 Questions: #1- I recently purchased a heat pump to heat my inground pool. The pump requires a 220V 50Amp power supply. I have run that source from my main panel to a disconnect that contains a 50Amp GFCI Breaker in it. This is commonly used for Jacuzzi's. My question is did I need to a neutral feed along with my 2 hots and ground in order for the GFCI Breaker in the disconnect to work properly? The unit I am wiring does not need the neutral so I did not run it. Now I am wondering if I should have for the GFCI Breaker???
#2 - I need to bond this new piece of equipment and was going to bond onto the bonding lug of existing pool pump. This already has 1 piece of #10 solid copper wire in it from the frame of the pool. My plan was to put another #10 solid copper wire in the lug and then the other end in the bonding lug of the heat pump. Is this be a sufficient and safe bond?
Any thoughts and comments would be appreciated.

#1 No yo do not need a neutral for the double GFCI to work properly.

#2 not sure. I let some one else answer this one.

anything within 5' of that pool must have the bonding grid. You need only #8 bare which is what you may have there now(appears larg). This is seperate from all current carrying wires of pool and grounded conductor. You should be OK. Do you have a insulated green leading to pump, this is required. NOT just covered as in UF cable? Hang in for WG final say in this as pools are a very touchy subject with codes. Check out pool Y & G box atop for pool wiring.( I was unable to open maybr you'll have better luck).

Yes I ran all strander #6 wire from the panel. 1-Red, 1-Black, & 1-Green in pipe buried 12"-18" (where I could). This goes to directly to the 50 Amp GFCI Breaker disconnect near the heat pump. The Heat pump itself is about 10' from the pool.
