Welcome to our forum.
Congrats! Glad your LED lighting is working properly. You will definitely enjoy the spa at night now
That's backwards. Whoever hooked your spa up got the two circuits reversed:The 30 amp breaker is supposed to run only the heater, and the 20 amp breaker is supposed to run everything else from the control system to the pumps. The 20 will keep popping everytime the heater kicks in - get your electrician or installer back and have them swap those wires:The two largest wires go to the hots on the 30 amp breaker, and there is no neutral wire for this breaker.Those two wires should be on the #1 and #3 connectors at the spa end.
