Cutler Hammer Classic disconnect with two pole 30 A, & single pole 20 A, both GFCI breakers with neutral pigtails to neutral bus. THHN/THWN stranded: # 10 hots, # 10 neutral, # 8 ground, # 12 hot & # 12 neutral to the tub location. Tub installer did the final hookup. Only the # 10 neutral was used by the tub installer.
How can both GFCI protected loads share the # 10 neutral ? Thank You
