I just installed a hot tub in my garage. The service panel has a 30amp and a 20 amp gfci breaker that run the heater and jets. The service panel is fed by the garage panel. There is a 50 amp breaker that feeds the service panel and two 20 amp breakers that feed the lights and outlets in the garage. When I turn on the jets the breaker at the main panel in the house trips. The garage is fed by two 30 amp breakers. Is the problem that I have 90 amps worth of breakers in the garage panel being fed by 60 amps in the main panel?
The wire that feeds the garage is AIM 10 3 WG UF.
