hot tub gfi breaker tripping
 
my hot tub 50 amp square d gfi breaker will not reset. I moved it to my range 50 amp breaker and it still trips. Is it faulty?

Sounds like something shorted to ground, may take some searching to find. You'll have to get a meter and start unhooking each component at a time and test it. I had to do this on ours and it turned out to be the heater, which is actually a pretty common part to cause this problem.
I guess start with the heater first.

Now that I've re read your post, are you saying that you tested the GFI to your range, or did your wire the hot tub to the range breaker temporarily? Your gonna have to repost something more clear, I may have jumped the gun on my reply.

Pump or heater are the two first places I would be looking at.

I removed the 50amp breaker for my range, which is a standard breaker, and inserted the 50 amp GFI hot tub breaker in the space of the range breraker.

To test the breaker on the range circuit, you would need to remove the neutral of the range circuit from the neutral bar and install it on the breaker. Then run the neutral pigtail from the GFI breaker to the neutral bar.

Keep it simple
 
Let's start with: What is the make and model of hot tub?

Reinstall the GFCI breaker and wire it to the hot tub. Make certain the LOAD NEUTRAL (usually the white wire) from the hot tub is connected to the breaker (Some 220V tubs only have 3 wires so there may not be a neutral wire).

Try to engage the breaker. If it trips, unplug or otherwise disconnect components one at a time until the breaker stays on. Start with the ozonator (if you have one) then the blower (if you have one) then the pump(s).

If you have all the components unplugged and the breaker still trips, disconnect the heater. If the breaker stays on you have a bad heater. Leave the heater disconnected.

TURN THE POWER OFF and reconnect all the other components.

Turn the power back on. If everything else works you have a bad heater which is the most common cause of GFCI tripping in hot tubs.

Thanks K Buz for that info. I did what you said and the breaker does turn on the range with out tripping.
When the breaker was on the hot tub circuit, (the hot tub has a separate panel box at a different location), the neutral from the hot tub circuit was on the neutral bar, not on the breaker. I have had the hot tub for over seven years and has worked fine all this time.

That would be correct because your hot tub is only 240 volts and has no neutral for 120 volt loads. In this screnario a neutral is ran to the spa box from the main/sub panel and is connected to the neutral bar ... not to the breaker. The curly pigtail from the gfci breaker is then connected to the neutral bar of the spa box. It should look like this ....
