Inground pool subpanel 70amps. The pump, heat pump, and pool light are powered by it. Pump is on a gfci breaker. I put a 20 amp breaker in the subpanel to control a ceiling fan with a light in our new sunroom. Randomly the pool pump gfci breaker will trip when operating the switch for the ceiling fan. The light will not trip the pump's gfci. The motor for the fan is the only thing that randomly trips the pump. What gives?
