Gfci breaker for spa

Melisa, Breaker/GFI may be going bad. You may have to get an electrician to check for short or faulty motor/heater, etc. Check the attached links,instruction and guides, Good luck

Troubleshooting tripping hot tub GFCI breaker
Hot tub GFI keeps tripping
Spa Circuit Breaker Mysteriously Tripping Any Clues Portable Hot Tubs amp...

Sounds like wet or bad wiring somewhere but u should do a visual inspection of all the wires & connections first then through process of elimination. Turn off breaker disconnect all wires and connect one wire then turn breaker on & if it dosent pop the. Turn it off and connect one more wire and turn the breaker on & continue until you get the breaker to pop and the last wire or board u just connected is your problem & go from there.

Still would go with Miswired.
if this is an auxiliary GFCI Spa Disconnect,
240 VAC, 50 Amp, then...
All of the following needs to be this way:

• 4 wires from MAIN Circuit panel, into GFCI disconnect box, 2 hots, 1 Neutral, 1 ground
  • 2 hots go onto the disconnects Power Bus Bar for breaker
  • 1 white Nuetral goes to Isolated nuetral bus bar
  • 1 green Ground goes to ground lug directly on the box
• 1 GFCI in the auxiliary disconnect box
  • The White Pigtail of the GFCI Breaker goes onto the Isolated Nuetral bus bar. There are now two wires there.
• 4 wires come into box from Spa. (Unless the spa is Specifically a 3 Wire Connection Spa!)
  • 2 Hot/Line wires will go into the L1 & L2 lugs of the breaker respectively.
  • 1 White Nuetral Wire will go into breaker as well at the "Load Nuetral lug, usually marked as 'LN'.
  • It will NOT go on the Isolated Nuetral bus bar.
  • Green Ground wire will be connected to ground lug, 2 wires are now connected there.
• Connections at spa will be respectively connected: the 2 hots on line 1 and line 2. White wire goes to Nuetralnd green ground will go to a Ground Lug, most likely to metal control box.

If it's not wired in this manner, it is wired WRONG.

Because it is a GFCI. Try making sure that the grounds are all good. Maybe go the extra step of putting in grounding rods into the ground and grounding to the unit. These are just guesses.

This is happening when you first activate the GFCI then either the circuit board is installed incorrectly or it is bad.

Leaking heat element.
2 GFCI on same circuit.
Rat-chewed wire. Inspect wiring.
Nail through wire.
Melted wire nut in junction box.
Undersized wire and breaker has been overheating breaker, and breaker has gone bad.
Shorted breaker. Move wires to different same-size breaker.

Question is not fully clear.

2-pole 240Volt gfci circuit breaker requires the white wire be connected to neutral busbar.

Easy solution for 240Volt spa that comes with gfci:
Replace spa gfci with regular non-gfci breaker.
Install 2-pole GFCI breaker in main panel, and connect wire to spa breaker.

Having 2 breakers is not a problem.
Having 2 GFCI on same circuit is a problem.

#1. DO NOT GET INTO TUB FULL OF WATER WITH A GROUND FAULT.
2. There is a short. You need to get multimeter and start checking each part for current running to ground wire.
3) Power is ON. Connect power without GFCI.
4) Tape tester leads to wood sticks to keep hands away from power.
5) Do not touch anything directly or you will become the ground rod.
6) Ground wire must be present, and bonded back to main panel box.
7) Do not sit or touch directly on cement or bare ground. Do not touch or lean into anything made of metal.
8) Body and parts must be on sheet of plywood, or similar non-conductive dry surface.
9) Test each part with spa, but also test electric line coming from main box.
10) GFCI will also trip with any fault detected on line. So the wire coming to spa may have the fault.
11) Add a new dedicated line from main box to spa.

Your hot tub needs GFI protection because it is electrical, and people sit inside water that could be exposed to electric current.
You have a fault to ground that needs to be fixed.

Size 8 wire for 50Amp breaker.
Size 6 if tub is 50-100' feet away

Check for a water leak in the electrical areas of your spa... specifically look closely around the heater terminals, look for wet and corroded connections... If this spa is wired to a plug-in outlet, look at the GFCI plug assembly as well... You can also try disconnecting the blower, pump, heater, etc, from the control pack (one at a time) to determine which item is causing the tripping.
