A breaker box can be bought from many offline retailers such as Home Depot and Walmart and general hardware stores. Online retailers such as Amazon or eBay will also supply them. A breaker box protects your electricity circuits from overloading and will trip out, temporarily breaking the circuit to avoid damage.

the problem is between these two breakers or you have a faulty or oversized breaker closest to the spa.
A circuit breaker will trip if it is faulty or if the connected circuit has a short circuit or a connected device is trying to draw more current than the breaker rating. If you disconnect the output wire from the breaker and it still trips, it is a faulty breaker. If the breaker is tripping immediately when it is turned on then start disconnecting elements of the circuit to see what might be causing the problem. If everything was working and now isn't, it is likely that the wire from the breaker is nicked where it exits the box and is shorting to the feedthru connector.
