Welcome to our forum.
Model is a Beachcomber 730. As I haven't gotten the pre-delivery instructions yet, I don't know whether there are any breakers in the spa or not, but my assumption is no.
Per my discussions with Brewman, I connected the spa wires to a 60 amp, non-fused pull box that I installed on the side of the house about 8 feet from the spa. The lines from this go directly to the main circuit breaker panel.
