I have had this hot tub for about 6 years. It has a history of blowing an internal 20 amp fuze. But, lately it runs a little while and then trips the circuit breaker. Any ideas?

First up, is this a plug-in 120vac tub contained installation or a custom tub that is a 240V power connected up from a GFCI breaker box disconnect near the installation? Does the water circulation pump run by itself without tripping or blowing safety devices?
