Welcome to our forum.
I recently bought a Tiger River spa and my friend helped me hook it up and do all the wiring. He also is an Electrician. Before I read the manual he hooked it up to a 50 amp breaker in a sub panel. But also to a 50 amp breaker at the Shut off.My problem is that the heater won’t totally heat the tub and I can’t seem to get water in the tubs. The manual said to hook up a 20 amp breaker for the jets and a 30 amp breaker for the heater. Is that why it is not heating enough. Because it’s hooked upTo a 50 amp breaker instead ofthe separate 20 and 30 am breaker?
