Arc fault breaker and GFCI outlet in bathroom?
>>> do not connect this way.
Do not install 2 fault protections on same circuit.
Install the arc fault circuit breaker, and then remove bathroom GFCI, and replace with ordinary outlet, or switch-outlet.
How many outlets can be connected to a bathroom GFCI?
It depends on total boxes on circuit.
Count the boxes. Max 12 boxes per circuit breaker.

connect the neutral from the circuit to the afci breaker, and run the neutral that came on the afci breaker to the neutral bar in the panel. Make sure that the neutral that you connect from the circuit to the afci breaker is the one that belongs to the circuit that you're protecting or the afci wont work.
