Is it okay to use one dedicated circuit to wire both a dishwasher and a
garbage disposal?

P.S. Even though I will be using 12/2 NM wire, my plan is to use a
15-amp circuit breaker for that circuit. I do know that with 12/2 wire,
I could use a 20-am circuit breaker, but I have a personal preference
for using 15 amp circuit breakers on 12/2 wiring except when the circuit
is required to have a 20 amp circuit breaker.



It is recommended to put the GD and dishwasher on it's own 15 amp
circuit or use a 20 amp circuit if you want to put them both together.

The average DW can pull 10 amps and the GD can be between 4 and 8 amps.
If running the DW and turning the GD on, you will most likely trip the
breaker at 15 amps since both will have a spike amp at start up.
